Vaccination with JYNNEOS vaccine (Modified Vaccinia Ankara vaccine, Bavarian Nordic) to prevent monkeypox commenced shortly after confirmation of the first monkeypox case in the current outbreak in the United States on May 17, 2022 (1). To date, more than 27,000 cases have been reported across all 50 states, the District of Columbia (DC), and Puerto Rico.* JYNNEOS vaccine is licensed by the Food and Drug Administration (FDA) as a 0.5-mL 2-dose series administered subcutaneously 28 days apart to prevent smallpox and monkeypox infections (2) and has been found to provide protection against monkeypox infection during the current outbreak (3). The U.S. Department of Health and Human Services (HHS) allocated 1.1 million vials of JYNNEOS vaccine from the Strategic National Stockpile, with doses allocated to jurisdictions based on case counts and estimated size of population at risk (4). However, initial vaccine supplies were severely constrained relative to vaccine demand during the expanding outbreak. Some jurisdictions with highest incidence responded by prioritizing first dose administration during May-July (5,6). The FDA emergency use authorization (EUA) of 0.1 mL dosing for intradermal administration of JYNNEOS for persons aged ≥18 years on August 9, 2022, substantially expanded available vaccine supply

IntroductionFocusing on subpopulations that express the intention to receive a COVID-19 vaccination but are unvaccinated may improve the yield of COVID-19 vaccination efforts.MethodsA nationally representative sample of 789,658 U.S. adults aged ≥18 years participated in the National Immunization Survey Adult COVID Module from May 2021 to April 2022. The survey assessed respondents' COVID-19 vaccination status and intent by demographic characteristics (age, urbanicity, educational attainment, region, insurance, income, and race/ethnicity). This study compared composition and within-group estimates of those who responded that they definitely or probably will get vaccinated or are unsure (moveable middle) from the first and last month of data collection.ResultsBecause vaccination uptake increased over the study period, the moveable middle declined among persons aged ≥18 years. Adults aged 18-39 years and suburban residents comprised most of the moveable middle in April 2022. Groups with the largest moveable middles in April 2022 included persons with no insurance (10%), those aged 18-29 years (8%), and those with incomes below poverty (8%), followed by non-Hispanic Native Hawaiian or other Pacific Islander (7%), non-Hispanic multiple or other race (6%), non-Hispanic American Indian or Alaska Native persons (6%), non-Hispanic Black or African American persons (6%), those with below high school education (6%), those with high school education (5%), and those aged 30-39 years (5%).ConclusionsA sizable percentage of adults open to receiving COVID-19 vaccination remain in several demographic groups. Emphasizing engagement of persons who are unvaccinated in some racial/ethnic groups, aged 18-39 years, without health insurance, or with lower income may reach more persons open to vaccination.

Coronavirus disease has disproportionately affected persons in congregate settings and high-density workplaces. To determine more about the transmission patterns of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in these settings, we performed whole-genome sequencing and phylogenetic analysis on 319 (14.4%) samples from 2,222 SARS-CoV-2–positive persons associated with 8 outbreaks in Minnesota, USA, during March–June 2020. Sequencing indicated that virus spread in 3 long-term care facilities and 2 correctional facilities was associated with a single genetic sequence and that in a fourth long-term care facility, outbreak cases were associated with 2 distinct sequences. In contrast, cases associated with outbreaks in 2 meat-processing plants were associated with multiple SARS-CoV-2 sequences. These results suggest that a single introduction of SARS-CoV-2 into a facility can result in a widespread outbreak. Early identification and cohorting (segregating) of virus-positive persons in these settings, along with continued vigilance with infection prevention and control measures, is imperative.

The 2020 Sturgis motorcycle rally resulted in widespread transmission of severe acute respiratory syndrome coronavirus 2 across the United States. At least 649 coronavirus disease 2019 cases were identified, including secondary and tertiary spread to close contacts. To limit transmission, persons attending events should be vaccinated or wear masks and practice physical distancing if unvaccinated. Persons with a known exposure should be managed according to their coronavirus disease 2019 vaccination or prior infection status and may include quarantine and coronavirus disease 2019 testing.

The aim of the study was to assess barriers to Vaccines for Children (VFC) provider practices participating in the COVID-19 Vaccination Program and intentions to offer COVID-19 vaccination to children aged

Little is known about how the drivers of COVID-19 vaccination vary across the U.S. To inform vaccination outreach efforts, this study explores geographic variation in correlates of COVID-19 nonvaccination among adults.Participants were a nationally representative sample of U.S. adults identified through random-digit dialing for the National Immunization Survey-Adult COVID Module. Analyses examined the geographic and temporal landscape of constructs in the Behavioral and Social Drivers of Vaccination Framework among unvaccinated respondents from May 2021 to December 2021 (n=531,798) and sociodemographic and geographic disparities and Behavioral and Social Drivers of Vaccination predictors of COVID-19 nonvaccination from October 2021 to December 2021 (n=187,756).National coverage with at least 1 dose of COVID-19 vaccine was 79.3% by December 2021, with substantial geographic heterogeneity. Regions with the largest proportion of unvaccinated persons who would probably get a COVID-19 vaccine or were unsure resided in the Southeast and Midwest (Health and Human Services Regions 4 and 5). Both regions had similar temporal trends regarding concerns about COVID-19 and confidence in vaccine importance, although the Southeast had especially low confidence in vaccine safety in December 2021, lowest in Florida (5.5%) and highest in North Carolina (18.0%). The strongest Behavioral and Social Drivers of Vaccination correlate of not receiving a COVID-19 vaccination was lower confidence in COVID-19 vaccine importance (adjusted prevalence ratio=5.19, 95% CI=4.93, 5.47; strongest in the Northeast, Southwest, and Mountain West and weakest in the Southeast and Midwest). Other Behavioral and Social Drivers of Vaccination correlates also varied by region.Contributors to nonvaccination showed substantial geographic heterogeneity. Strategies to improve COVID-19 vaccination uptake may need to be tailored regionally.

Little information exists regarding Ebola vaccine rVSVΔGZEBOV-GP and pregnancy. The Sierra Leone Trial to Introduce a Vaccine against Ebola (STRIVE) randomized participants without blinding to immediate or deferred (18-24 weeks postenrollment) vaccination. Pregnancy was an exclusion criterion, but 84 women were inadvertently vaccinated in early pregnancy or became pregnant 15 days after vaccination) (45% [10/22]). No congenital anomalies were detected among 44 live-born infants examined. These data highlight the need for Ebola vaccination decisions to balance the possible risk for an adverse pregnancy outcome with the risk for Ebola exposure.

IntroductionEmployer vaccination requirements have been used to increase vaccination uptake among healthcare personnel (HCP). In summer 2021, HCP were the group most likely to have employer requirements for COVID-19 vaccinations as healthcare facilities led the implementation of such requirements. This study examined the association between employer requirements and HCP’s COVID-19 vaccination status and attitudes about the vaccine.MethodsParticipants were a national representative sample of United States (US) adults who completed the National Immunization Survey Adult COVID Module (NIS-ACM) during August–September 2021. Respondents were asked about COVID-19 vaccination and intent, requirements for vaccination, place of work, attitudes surrounding vaccinations, and sociodemographic variables. This analysis focused on HCP respondents. We first calculated the weighted proportion reporting COVID-19 vaccination for HCP by sociodemographic variables. Then we computed unadjusted and adjusted prevalence ratios for vaccination coverage and key indicators on vaccine attitudes, comparing HCP based on individual self-report of vaccination requirements.ResultsOf 12,875 HCP respondents, 41.5% reported COVID-19 vaccination employer requirements. Among HCP with vaccination requirements, 90.5% had been vaccinated against COVID-19, as compared to 73.3% of HCP without vaccination requirements—a pattern consistent across sociodemographic groups. Notably, the greatest differences in uptake between HCP with and without employee requirements were seen in sociodemographic subgroups with the lowest vaccination uptake, e.g., HCP aged 18–29 years, HCP with high school or less education, HCP living below poverty, and uninsured HCP. In every sociodemographic subgroup examined, vaccine uptake was more equitable among HCP with vaccination requirements than in HCP without. Finally, HCP with vaccination requirements were also more likely to express confidence in the vaccine’s safety (68.3% vs. 60.1%) and importance (89.6% vs 79.6%).ConclusionIn a large national US sample, employer requirements were associated with higher and more equitable HCP vaccination uptake across all sociodemographic groups examined. Our findings suggest that employer requirements can contribute to improving COVID-19 vaccination coverage, similar to patterns seen for other vaccines.

BACKGROUND: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) spreads rapidly amongst residents of skilled nursing facilities (SNFs). The rapid transmission dynamics and high morbidity and mortality that occur in SNFs emphasize the need for early detection of cases. We hypothesized that residents of SNFs infected with SARS-CoV-2 would demonstrate an acute change in either temperature or oxygen saturation (SpO2 ) prior to symptom onset. The Minnesota Department of Health (MDH) conducted a retrospective analysis of both temperature and SpO2 at two separate SNFs to assess the utility of these quantitative markers to identify SARS-CoV-2 infection prior to the development of symptoms. METHODS: A retrospective analysis was conducted of 165 individuals positive for SARS-CoV-2 who were residents of SNFs that experienced coronavirus disease 2019 (COVID-19) outbreaks during April-June 2020 in a metropolitan area of Minnesota. Age, sex, symptomology, temperature and SpO2 values, date of symptom onset, and date of positive SARS-CoV-2 test were analyzed. Temperature and SpO2 values for the period 14 days before and after the date of initial positive test were included. Descriptive analyses evaluated changes in temperature and SpO2 , defined as either exceeding a set threshold or demonstrating an acute change between consecutive measurements. RESULTS: Two (1%) residents had a temperature value ≥100°F, and 30 (18%) had at least one value ≥99°F within 14 days before symptom development. One hundred and sixteen residents (70%) had at least one SpO2 value ≤94%, while 131 (80%) had an acute decrease in SpO2 of ≥3% between consecutive values in the 14 days prior to symptom onset. CONCLUSIONS: Our results suggest that acute change in SpO2 might be useful in the identification of SARS-CoV-2 infection prior to the development of symptoms among residents living in SNFs. Facilities may consider adding SpO2 to daily temperature and symptom screening checklists to improve early detection of residents of SNFs infected with SARS-CoV-2.

During the 2018-2020 Ebola virus disease (EVD) outbreak in the Democratic Republic of the Congo, risk communication and community engagement (RCCE) were prioritized in geographic areas in Uganda considered at high risk of introduction of EVD. To inform EVD preparedness in Uganda, we evaluated community perceptions and prevention practices related to EVD in 6 districts in Uganda.In March 2020, we conducted a population-based survey in 6 purposively selected districts in Uganda using multistage cluster sampling. We examined differences between districts classified as high- versus low risk for EVD in terms of their message exposure from RCCE; risk perception; and EVD knowledge, attitudes, and prevention practices.A total of 3,485 respondents were interviewed (91% response rate). EVD message exposure was more common in the high- versus low-risk districts. EVD risk perceptions were low overall but greater in the high- versus low-risk districts. Comprehensive knowledge was significantly greater in the high- versus low-risk districts (adjusted prevalence ratio [aPR] 1.61, 95% confidence interval [CI]=1.35, 1.93). Respondents' engagement in all 3 EVD prevention practices (frequent handwashing with soap, avoiding physical contact with suspected Ebola patients, and avoiding burials involving contact with a corpse) was very low (4%). However, respondents with comprehensive knowledge were more likely to engage in all 3 EVD prevention practices compared to respondents without comprehensive knowledge (aPR 1.87, 95% CI=1.08, 3.25).Our findings suggest that while RCCE efforts as part of EVD outbreak preparedness may have contributed to higher EVD knowledge in the targeted high-risk districts, uptake of prevention behaviors was similarly low across districts. In a non-outbreak setting, implementing targeted RCCE strategies may not be sufficient to motivate people to adopt protective behaviors in the absence of a high threshold of perceived threat such as in an active outbreak.

Congregate settings and high-density workplaces have endured a disproportionate impact from COVID-19. In order to provide further understanding of the transmission patterns of SARS-CoV-2 in these settings, whole genome sequencing (WGS) was performed on samples obtained from 8 selected outbreaks in Minnesota from March – June, 2020. WGS and phylogenetic analysis was conducted on 319 samples, constituting 14.4% of the 2,222 total SARS-CoV-2-positive individuals associated with these outbreaks. Among the sequenced specimens, three LTCFs and both correctional facilities had spread associated with a single genetic sequence. A fourth LTCF had outbreak cases associated with two distinct sequences. In contrast, cases associated with outbreaks in the two meat processing plants represented multiple SARS-CoV-2 sequences. These results suggest that a single introduction of SARS-CoV-2 into a facility can result in a widespread outbreak, and early identification and cohorting of cases, along with continued vigilance with infection prevention and control measures is imperative.

Background Since the declaration of the 10th Ebola Virus Disease (EVD) outbreak in DRC on 1st Aug 2018, several neighboring countries have been developing and implementing preparedness efforts to prevent EVD cross-border transmission to enable timely detection, investigation, and response in the event of a confirmed EVD outbreak in the country. We describe Uganda’s experience in EVD preparedness. Results On 4 August 2018, the Uganda Ministry of Health (MoH) activated the Public Health Emergency Operations Centre (PHEOC) and the National Task Force (NTF) for public health emergencies to plan, guide, and coordinate EVD preparedness in the country. The NTF selected an Incident Management Team (IMT), constituting a National Rapid Response Team (NRRT) that supported activation of the District Task Forces (DTFs) and District Rapid Response Teams (DRRTs) that jointly assessed levels of preparedness in 30 designated high-risk districts representing category 1 (20 districts) and category 2 (10 districts). The MoH, with technical guidance from the World Health Organisation (WHO), led EVD preparedness activities and worked together with other ministries and partner organisations to enhance community-based surveillance systems, develop and disseminate risk communication messages, engage communities, reinforce EVD screening and infection prevention measures at Points of Entry (PoEs) and in high-risk health facilities, construct and equip EVD isolation and treatment units, and establish coordination and procurement mechanisms. Conclusion As of 31 May 2019, there was no confirmed case of EVD as Uganda has continued to make significant and verifiable progress in EVD preparedness. There is a need to sustain these efforts, not only in EVD preparedness but also across the entire spectrum of a multi-hazard framework. These efforts strengthen country capacity and compel the country to avail resources for preparedness and management of incidents at the source while effectively cutting costs of using a “fire-fighting” approach during public health emergencies.

The Sierra Leone Trial to Introduce a Vaccine against Ebola (STRIVE), a phase 2/3 trial of investigational rVSV∆G-ZEBOV-GP vaccine, was conducted during an unprecedented Ebola epidemic. More than 8600 eligible healthcare and frontline response workers were individually randomized to immediate (within 7 days) or deferred (within 18–24 weeks) vaccination and followed for 6 months after vaccination for serious adverse events and Ebola virus infection. Key challenges included limited infrastructure to support trial activities, unreliable electricity, and staff with limited clinical trial experience. Study staff made substantial infrastructure investments, including renovation of enrollment sites, laboratories, and government cold chain facilities, and imported equipment to store and transport vaccine at ≤−60oC. STRIVE built capacity by providing didactic and practical research training to >350 staff, which was reinforced with daily review and feedback meetings. The operational challenges of safety follow-up were addressed by issuing mobile telephones to participants, making home visits, and establishing a nurse triage hotline. Before the Ebola outbreak, Sierra Leone had limited infrastructure and staff to conduct clinical trials. Without interfering with the outbreak response, STRIVE responded to an urgent need and helped build this capacity. Clinical Trials Registration.

The West Africa Ebola epidemic stimulated rapid implementation of Ebola vaccine trials in the 3 highly affected countries. In Sierra Leone, we studied the recombinant vesicular stomatitis virus Ebola vaccine (rVSV∆G-ZEBOV-GP) safety and efficacy. The Sierra Leone Trial to Introduce a Vaccine against Ebola (STRIVE) was a randomized, unblinded Phase 2/3 trial with phased vaccine introduction, no placebo, and concurrent evaluation of vaccine safety and efficacy. Healthcare and frontline response workers in 5 districts were randomized to immediate or deferred (18–24 weeks later) vaccination and followed for 6 months postvaccination. We enrolled 8651 participants from April through August 2015; 7998 were vaccinated. No participants developed Ebola virus disease so an efficacy assessment was not possible. Overall, 132 (1.5%) participants experienced serious adverse events (SAEs); none were vaccine-related. In a detailed safety substudy (N = 436), vaccinated participants reported significantly more systemic adverse events (AEs) within 7 days than unvaccinated participants including fever higher than 38°C (20.5% vs 3.9%), headache (71.2% vs 22.1%), fatigue (50.7% vs 10.4%), and joint pain (31.7% vs 6.5%); most AEs were mild to moderate severity and resolved within 5 days. During days 5-28, vaccinated participants more commonly reported joint pain (17.0% vs 4.8%) and rash (7.8% vs 1.7%) (P

The Sierra Leone Trial to Introduce a Vaccine against Ebola (STRIVE) was the first investigational vaccine trial conducted in Sierra Leone. STRIVE enrolled and vaccinated about 8000 healthcare and frontline workers and followed them for 6 months post-vaccination. Few in-country healthcare workers had previous experience with clinical trials. Retired nurses, veteran nurses, and recently graduated nurses were hired to fill critical study roles including study site management, screening participants for enrollment, vaccine administration, post-vaccination follow-up, and providing clinical nursing care and advice. In addition to role-specific training, nurses received general training on the study protocol and implementation, Good Clinical Practices, and documentation for clinical trials. Training in documentation and supervision was especially challenging; ongoing refresher training should be built into standard operating procedures for future similar clinical studies. Using local nurses to conduct study activities had both short- and long-term positive impacts for the study, the nurses themselves, the community, and the country’s health system.

The Sierra Leone Trial to Introduce a Vaccine Against Ebola (STRIVE), an Ebola vaccine trial conducted during the 2014–2016 Ebola epidemic, coordinated with the Sierra Leone national response to identify Ebola cases among trial participants. The early symptoms of Ebola are similar to common vaccine reactions, so it was important to differentiate these to avoid unnecessary referral to an Ebola facility and an increased risk of Ebola exposure. STRIVE developed a modified version of the national case definition and case management algorithm to distinguish between symptoms associated with both Ebola and vaccination with the candidate Ebola vaccine (rVSV∆G-ZEBOV-GP) from those typically associated only with Ebola. For participants who presented ≤48 hours after vaccination, we used the more stringent modified case definition to trigger referral for Ebola evaluation. Participants whose symptoms did not meet case definitions could also be referred to an Ebola facility, based on clinical judgment. No Ebola cases were diagnosed among the 8651 STRIVE participants. Fifty participants were evaluated for Ebola, of whom 34 (68%) were tested after vaccination; 22 deceased participants, all of whom underwent postmortem Ebola testing, as required during the Ebola epidemic, and had negative test results, were excluded from analysis. Seven of 34 participants (21%) had symptom onset ≤48 hours after vaccination, of whom 3 met the modified case definition. The most common diagnosis among those evaluated for Ebola was malaria. STRIVE demonstrates the feasibility of conducting Ebola surveillance among persons vaccinated with rVSV-ZEBOV during an Ebola epidemic and introduces a modified case definition and case management algorithm to distinguish vaccine reactions from early symptoms of Ebola that may be useful for reducing unnecessary Ebola evaluations among persons vaccinated during Ebola outbreaks.

Vaccination against Ebola virus disease is a tool that may limit disease transmission and deaths in future outbreaks, integrated within traditional Ebola outbreak prevention and control measures. Although a licensed Ebolavirus vaccine (EV) is not yet available, the 2014–2016 West African Ebola outbreak has accelerated EV clinical trials and given public health authorities in Guinea, Liberia, and Sierra Leone experience with implementation of emergency ring vaccination. As evidence supporting the use of EV during an outbreak response has become available, public health authorities in at-risk countries are considering how to integrate EV into future emergency Ebola responses and for prevention in high-risk groups, such as healthcare workers and frontline workers (HCW/FLWs), even before an EV is licensed. This review provides an overview of Ebola epidemiology, immunology, and evidence to inform regional and country-level decisions regarding EV delivery during an emergency response and to at-risk populations before a licensed vaccine is available and beyond. Countries or regions planning to use EV will need to assess factors such as the likelihood of a future Ebolavirus outbreak, the most likely species to cause an out-break, the availability of a safe and effective EV (unlicensed or licensed) for the affected population, capacity to implement Ebola vaccination in conjunction with standard Ebola outbreak control measures, and availability of minimum essential resources and regulatory requirements to implement emergency Ebola vaccination. Potential emergency vaccination strategies for consideration include ring or geographically targeted community vaccination, HCW/FLW vaccination, and mass vaccination. The development of guidelines and protocols for Ebola vaccination will help ensure that activities are standardized, evidence-based, and well-coordinated with overall Ebola outbreak response efforts in the future.

BACKGROUND In resource-limited settings, decentralization of HIV care and treatment is a cornerstone of universal care and rapid scale-up. We compared trends in pediatric enrollment and outcomes at primary (PHFs) vs secondary/tertiary health facilities (SHFs). METHODS Using aggregate program data reported quarterly from 274 public facilities in Kenya, Lesotho, Mozambique, Rwanda, and Tanzania from January 2008 to March 2010, we examined trends in number of children younger than 15 years of age initiating antiretroviral treatment (ART) by facility type. We compared clinic-level lost to follow-up (LTFU) and mortality per 100 person-years (PYs) on ART during the period by facility type. RESULTS During the 2-year period, 17,155 children enrolled in HIV care and 8475 initiated ART in 182 (66%) PHFs and 92(34%) SHFs. PHFs increased from 56 to 182, whereas SHFs increased from 72 to 92 sites. SHFs accounted for 71% of children initiating ART; however, the proportion of children initiating ART each quarter at PHFs increased from 17% (129) to 44% (463) in conjunction with an increase in PHFs during observation period. The average LTFU and mortality rates for children on ART were 9.8/100 PYs and 5.2/100 PYs, respectively, at PHFs and 20.2/100 PYs and 6.0/100 PYs, respectively, at SHFs. Adjusted models show PHFs associated with lower LTFU (adjusted rate ratio = 0.55; P = 0.022) and lower mortality (adjusted rate ratio = 0.66; P = 0.028). CONCLUSIONS The expansion of pediatric services to PHFs has resulted in increased numbers of children on ART. Early findings suggest lower rates of LTFU and mortality at PHFs. Successful scale-up will require further expansion of pediatric services within PHFs.

BACKGROUND Retention of children in HIV care is essential for prevention of disease progression and mortality. METHODS Retrospective cohort of children (aged 0 to

Objective: HIV-infected women need access to safe and effective contraception. Recent animal and human data suggest that hormonal contraception may accelerate HIV disease progression. Methods: We compared the incidence of HIV disease progression among antiretroviral therapy-naive women with and without exposure to hormonal contraception at 13 sites in Africa and Asia. Disease progression was defined as becoming eligible for antiretroviral therapy or death. Results: Between 1 August 2002 and 31 December 2007, the MTCT-Plus programs enrolled 7846 women. In total, 4109 (52%) women met eligibility criteria for this analysis and contributed 5911 person-years of follow-up (median follow-up, 379 days; interquartile range, 121–833). At baseline, 3064 (75%) women reported using either no contraception or a nonhormonal method, whereas 823 (20%) reported using implants/injectables and 222 (5%) reported using oral contraceptive pills. The disease progression outcome was met by 944 (29%) women (rate, 18.3/100 woman-years). Neither implants/injectables (adjusted hazard ratio 1.0, 95% confidence interval 0.8–1.1) nor oral contraceptive pills (adjusted hazard ratio 0.8, 95% confidence interval 0.6–1.1) were associated with disease progression. Treating contraceptive method as a time-varying exposure did not change this negative finding. Conclusion: This multicountry cohort analysis provides some reassurance that hormonal contraception is not associated with HIV disease progression. Further research is needed to address the contraceptive needs of HIV-infected women.

The objective of the study was to evaluate the feasibility, acceptability, and accuracy of rapid human immunodeficiency virus (HIV) testing during labor. The Mother-Infant Rapid Intervention at Delivery (MIRIAD) study was a prospective, multicenter study that offered voluntary, rapid HIV testing to women with undocumented HIV status at 17 hospitals in 6 cities. Of 12,481 eligible women, 74% were approached for participation and 85.5% of those approached accepted rapid HIV testing. Among 7753 women tested, MIRIAD identified 52 (0.7%) HIV-infected women. The time between obtaining the blood sample for the rapid test and reporting the results to the health care provider was shorter for hospitals utilizing point-of-care testing than in hospitals utilizing laboratory-based testing (30 minutes vs 68 minutes; P < .0001), and point-of-care testing strategies were 14 times more likely to have a short turnaround as laboratory testing strategies. Routine rapid testing during labor provides a feasible, acceptable, and accurate way to identify HIV-infected women before delivery.

Summary Freedman D, Koenig LJ, Wiener J, Abrams EJ, Carter RJ, Tepper V, Palumbo P, Nesheim S, Bulterys M. Challenges to re-enrolling perinatally HIV-infected and HIV-exposed but uninfected children into a prospective cohort study: strategies for locating and recruiting hard-to-reach families. Paediatric and Perinatal Epidemiology 2006; 20: 338–347. Children infected with the human immunodeficiency virus (HIV) are living longer. Studies aimed at understanding the health and well-being of these children as they age into adolescence are enhanced by research designs that include appropriate comparison groups. HIV-exposed but uninfected children are one such comparison group; however, recruitment of this comparison group is challenging because uninfected children may no longer be followed at tertiary care centres, and some may be in foster care or no longer living with their biological parents. This paper describes the recruitment methods, sampling plan, and factors associated with enrolling perinatally HIVinfected children and a comparison group of HIV-exposed but uninfected children into the HIV Follow-up Of Perinatally Exposed Children (PACTS-HOPE) prospective cohort study. The source population consists of HIV-infected and uninfected children originally enrolled in the Perinatal AIDS Collaborative Transmission Study (PACTS). Recruitment took place at paediatric HIV clinics in four US locations between March 2001 and March 2003. A total of 182 HIV-infected and 180 uninfected children were enrolled. Enrolment of uninfected children was much harder than that of infected children because the former often could not be located. After adjusting for site and birth-year category, uninfected children born to white mothers were significantly less likely to be enrolled ( P < 0.01). There was a trend for infected and uninfected children of mothers with a history of injection drug use to enrol at lower rates. Although recruitment of the uninfected comparison group was challenging, it was nevertheless facilitated by hierarchical recruitment techniques, involvement of family networks, and continuity of study staff. The PACTS-HOPE cohort will provide opportunities for future research aimed at understanding the unique effects of HIV on the well-being of HIV-infected children.

Background: Although there is widespread interest in understanding how models of care for delivering antiretroviral therapy (ART) may influence patient outcomes, family-focused approaches have received little attention. In particular, there have been few investigations of whether the co-enrollment of HIV-infected family members may improve adult ART outcomes over time. Methods: We examined the association between co-enrollment of HIV-infected family members into care and outcomes of women initiating ART in 12 HIV care and treatment programs across sub-Saharan Africa. Using data from the mother-to-child transmission-(MTCT) Plus Initiative, women starting ART were categorized according to the co-enrollment of an HIV-infected partner and/or HIV-infected child within the same program. Mortality and loss to follow-up were assessed for up to 5 years after women's ART initiation. Results: Of the 2877 women initiating ART included in the analysis, 31% (n = 880) had at least 1 HIV-infected family member enrolled into care at the same program, including 24% (n = 689) who had an HIV-infected male partner, and 10% (n = 295) who had an HIV-infected child co-enrolled. There was no significant difference in the risk of death of women by family co-enrollment status (P = 0.286). However, the risk of loss to follow-up was greatest among women who did not have an HIV-infected family member co-enrolled (19% after 36 months on ART) compared with women who had an HIV-infected family member co-enrolled (3%–8% after 36 months on ART) (P < 0.001). These associations persisted after adjustment for demographic and clinical covariates and were consistent across countries and care programs. Discussion: These data provide novel evidence for the association between adult outcomes on ART and co-enrollment of HIV-infected family members into care at the same program. Interventions that build on women's family contexts warrant further consideration in both research and policies to promote retention in ART services across sub-Saharan Africa.

To assess the risk of perinatal human immunodeficiency virus (HIV) transmission in HIV-infected women clinically diagnosed with genital herpes simplex virus (HSV) infection during pregnancy.This retrospective analysis included 402 HIV-infected pregnant women who enrolled from 1994-1999 in a multicenter prospective cohort study in New York City, who delivered a liveborn singleton infant with known HIV infection status, and who had information on diagnosis of genital HSV infection during pregnancy. Study participants were determined to have genital HSV infection during pregnancy by documentation of clinical diagnosis.Forty-six (11.4%) of the study participants delivered HIV-infected infants. Twenty-one (5.2%) had clinical diagnosis of genital HSV infection in pregnancy. Six (28.6%) of the 21 HIV-infected women with a clinical diagnosis of genital HSV infection delivered an HIV-infected infant. In univariate analyses, HIV-infected pregnant women with clinical diagnosis of genital HSV infection during pregnancy had a significantly increased risk of perinatal HIV transmission (odds ratio 3.4, 95% confidence interval 1.3-9.3; P = .02). When other factors associated with perinatal HIV transmission were included in a logistic regression model (lack of zidovudine therapy during pregnancy or delivery, prolonged rupture of membranes, and preterm delivery), clinical diagnosis of genital HSV infection during pregnancy remained a significant independent predictor of perinatal HIV transmission (adjusted odds ratio 4.8, 95% confidence interval 1.3-17.0; P = .02).Clinical diagnosis of genital HSV infection during pregnancy in HIV-infected women may be a risk factor for perinatal HIV transmission. If future studies confirm this association, therapy to suppress genital HSV reactivation during pregnancy may be a strategy to reduce perinatal HIV transmission.

Objectives:To characterize risk factors associated with pneumococcal disease and asymptomatic colonization during an outbreak of multidrug-resistantStreptococcus pneumoniae(MDRSP) among AIDS patients in a long-term–care facility (LTCF), evaluate the efficacy of antimicrobial prophylaxis in eliminating MDRSP colonization, and describe the emergence of fluoroquinolone resistance in the MDRSP outbreak strain.Design:Epidemiologic investigation based on chart review and characterization of SP strains by antimicrobial susceptibility testing and PFGE and prospective MDRSP surveillance.Setting:An 80-bed AIDS-care unit in an LTCF.Participants:Staff and residents on the unit.Results:From April 1995 through January 1996, 7 cases of MDRSP occurred. A nasopharyngeal (NP) swab survey of all residents (n = 65) and staff (n = 70) detected asymptomatic colonization among 6 residents (9%), but no staff. Isolates were sensitive only to rifampin, ofloxacin, and vancomycin. A 7-day course of rifampin and ofloxacin was given to eliminate colonization among residents: NP swab surveys at 1, 4, and 10 weeks after prophylaxis identified 1 or more colonized residents at each follow-up with isolates showing resistance to one or both treatment drugs. Between 1996 and 1999, an additional 6 patients were diagnosed with fluoroquinolone-resistant (FQ-R) MDRSP infection, with PFGE results demonstrating that the outbreak strain had persisted 3 years after the initial outbreak was recognized.Conclusions:Chemoprophylaxis likely contributed to the development of a FQ-R outbreak strain that continued to be transmitted in the facility through 1999. Long-term control of future MDRSP outbreaks should rely primarily on vaccination and strict infection control measures.

Objective To determine the effect of infant feeding practices on postpartum weight change among HIV-infected and -uninfected women in South Africa. Methods In a non-randomised intervention cohort study of antiretroviral therapy-naïve women in South Africa, infants were classified as exclusive (EBF), mixed (MF) or non-breastfed (NBF) at each visit. We analysed infant feeding cumulatively from birth to 5 months using 24-hour feeding history (collected weekly for each of the preceding 7 days). Using generalised estimating equation mixed models, allowing for repeated measures, we compared postpartum weight change (kg) from the first maternal postpartum weight within the first 6 weeks (baseline weight) to each subsequent visit through 24 months among 2340 HIV-infected and -uninfected women with live births and at least two postpartum weight measurements. Results HIV-infected (−0.2 kg CI: −1.7 to 1.3 kg; P = 0.81) and -uninfected women (−0.5 kg; 95% CI: −2.1 to 1.2 kg; P = 0.58) had marginal non-significant weight loss from baseline to 24 months postpartum. Adjusting for HIV status, socio-demographic, pregnancy-related and infant factors, 5-month feeding modality was not significantly associated with postpartum weight change: weight change by 24 months postpartum, compared to the change in the reference EBF group, was 0.03 kg in NBF (95% CI: −2.5 to +2.5 kg; P = 0.90) and 0.1 kg in MF (95% CI: −3.0 to +3.2 kg; P = 0.78). Conclusion HIV-infected and -uninfected women experienced similar weight loss over 24 months. Weight change postpartum was not associated with 5-month breastfeeding modality among HIV-infected and -uninfected women.

Pre-existing kidney disease in HIV-infected patients may necessitate dose modification of antiretroviral therapy (ART). Despite increasing ART availability, there are few prevalence studies of chronic kidney disease in HIV-infected individuals across multiple African countries.Routine laboratory data obtained before ART initiation were used to evaluate prevalence and predictors of decreased creatinine clearance (CrCl) in participants of the MTCT-Plus Initiative from 7 sub-Saharan countries. Cockcroft-Gault equation was used to estimate CrCl and logistic regression modeling to identify factors associated with CrCl50 mL/min.Of 2495 individuals evaluated, median age was 30 years (interquartile range: 27-35); 70% were women. Median CD4+ cell count was 295 (interquartile range: 173-450); 78% were World Health Organization stage 1/2. Median CrCl was 95 mL/min. Overall, 3.4% [95% confidence interval (CI): 2.7 to 4.1] of patients had a CrCl50 mL/min. Age30 years (odds ratio = 2.06; 95% CI: 1.23 to 3.45) and CD4+ count50 cells per cubic millimeter (odds ratio = 5.4 for CD4+50, 95% CI: 2.5 to 11.9) were associated with CrCl50 mL/min.The prevalence of clinically significant kidney disease was low in this relatively healthy population of HIV-infected adults, and few participants would have required ART dose reductions. These findings support recent World Health Organization guidelines to initiate ART without routine laboratory screening. Our findings suggest that available laboratory resources could be targeted to older persons and those with very low CD4+ cell count.

Background Mother-to-child transmission (MTCT) of HIV has been eliminated from the developed world with the introduction of multi-drug antiretroviral (md-ARV) regimens for the prevention of MTCT (PMTCT); but remains the major cause of HIV infection among sub-Saharan African children. This study compares two service delivery models of PMTCT interventions and documents the lessons learned and the challenges encountered during the transition from single-dose nevirapine (sd-nvp) to md-ARV regimens in a resource-limited setting. Methods Program data collected from 32 clinical sites was used to describe trends and compare the performance (uptake of HIV testing, CD4 screening and ARV regimens initiated during pregnancy) of sites providing PMTCT as a stand-alone service (stand-alone site) versus sites providing PMTCT as well as antiretroviral therapy (ART) (full package site). CD4 cell count screening, enrolment into ART services and the initiation of md-ARV regimens during pregnancy, including dual (zidovudine [AZT] +sd-nvp) prophylaxis and highly active antiretroviral therapy (HAART) were analysed. Results From July 2006 to December 2008, 1,622 pregnant women tested HIV positive (HIV+) during antenatal care (ANC). CD4 cell count screening during pregnancy increased from 60% to 70%, and the initiation of md-ARV regimens increased from 35.5% to 97% during this period. In 2008, women attending ANC at full package sites were 30% more likely to undergo CD4 cell count assessment during pregnancy than women attending stand-alone sites (relative risk (RR) = 1.3; 95% confidence interval (CI): 1.1-1.4). Enrolment of HIV+ pregnant women in ART services was almost twice as likely at full package sites than at stand-alone sites (RR = 1.9; 95% CI: 1.5-2.3). However, no significant differences were detected between the two models of care in providing md-ARV (RR = 0.9; 95% CI: 0.9-1.0). Conclusions All sites successfully transitioned from sd-nvp to md-ARV regimens for PMTCT. Full package sites offer the most efficient model for providing immunological assessment and enrolment into care and treatment of HIV+ pregnant women. Strengthening the capacity of stand-alone PMTCT sites to achieve the same objectives is paramount.

A multicountry cohort study in sub-Saharan Africa by Landon Myer and colleagues reveals higher pregnancy rates in HIV-infected women on antiretroviral therapy (ART)., Background With the rapid expansion of antiretroviral therapy (ART) services in sub-Saharan Africa there is growing recognition of the importance of fertility and childbearing among HIV-infected women. However there are few data on whether ART initiation influences pregnancy rates. Methods and Findings We analyzed data from the Mother-to-Child Transmission-Plus (MTCT-Plus) Initiative, a multicountry HIV care and treatment program for women, children, and families. From 11 programs in seven African countries, women were enrolled into care regardless of HIV disease stage and followed at regular intervals; ART was initiated according to national guidelines on the basis of immunological and/or clinical criteria. Standardized forms were used to collect sociodemographic and clinical data, including incident pregnancies. Overall 589 incident pregnancies were observed among the 4,531 women included in this analysis (pregnancy incidence, 7.8/100 person-years [PY]). The rate of new pregnancies was significantly higher among women receiving ART (9.0/100 PY) compared to women not on ART (6.5/100 PY) (adjusted hazard ratio, 1.74; 95% confidence interval, 1.19–2.54). Other factors independently associated with increased risk of incident pregnancy included younger age, lower educational attainment, being married or cohabiting, having a male partner enrolled into the program, failure to use nonbarrier contraception, and higher CD4 cell counts. Conclusions ART use is associated with significantly higher pregnancy rates among HIV-infected women in sub-Saharan Africa. While the possible behavioral or biomedical mechanisms that may underlie this association require further investigation, these data highlight the importance of pregnancy planning and management as a critical but neglected component of HIV care and treatment services. Please see later in the article for the Editors' Summary, Editors' Summary Background Human immunodeficiency virus (HIV) causes Acquired Immunodeficiency Syndrome (AIDS), which is a major global cause of disease and death. More than 33 million people around the world are infected with HIV, with nearly 5,500 dying daily from HIV and AIDS-related complications. HIV/AIDS is especially problematic in sub-Saharan Africa, where it is the leading cause of death. There is no cure for HIV/AIDS, but medicines known as “antiretroviral therapy” (ART) can prolong life and reduce complications in patients infected with HIV. 97% of patients with HIV/AIDS live in low- and middle-income countries. According to the World Health Organization, nearly 10 million of these patients need ART. As patients' access to treatment is often hindered by the high cost and low availability of ART, global health efforts have focused on promoting ART use in resource-limited nations. Such efforts also increase awareness of how HIV is spread (contact with blood or semen, in sexual intercourse, sharing needles, or from mother to child during childbirth). ART reduces, but does not remove, the chance of a mother's passing HIV to her child during birth. Why Was This Study Done? By the end of 2007, 3 million HIV-infected patients in poor countries were receiving ART. Many of those treated with ART are young women of child-bearing age. Childbirth is an important means of spreading HIV in sub-Saharan Africa, where 60% of all HIV patients are women. This study questions whether the improved health and life expectancy that results from treatment with ART affects pregnancy rates of HIV-infected patients. The study explores this question in seven African countries, by examining the rates of pregnancy in HIV-infected women before and after they started ART. What Did the Researchers Do and Find? The authors looked at the records of 4,531 HIV-infected women enrolled in the Mother-to-Child-Transmission-Plus (MTCT-Plus) Initiative in seven African countries. MTCT -Plus, begun in 2002, is a family-centered treatment program that offers regular checkups, blood tests, counseling, and ART treatment (if appropriate) to women and their families. At each checkup, women's CD4+ cell counts and World Health Organization guidelines were used to determine their eligibility for starting ART. Over a 4-year period, nearly a third of the women starting ART experienced a pregnancy: 244 pregnancies occurred in the “pre-ART” group (women not receiving ART) compared to 345 pregnancies in the “on-ART” group (women receiving ART). The chance of pregnancy increased over time in the on-ART group to almost 80% greater than the pre-ART group, while remaining relatively low and constant in the pre-ART group. The authors noted that, as expected, other factors also increased the chances of pregnancy, including younger age, lower educational status, and use of nonbarrier contraception such as injectable hormones. What Do These Findings Mean? This study suggests that starting ART is associated with higher pregnancy rates in sub-Saharan Africa, nearly doubling the chances of a woman becoming pregnant. The reasons for this link are unclear. One possible explanation is behavioral: women receiving ART may feel more motivated to have children as their health and quality of life improve. However, the study did not examine how pregnancy desires and sexual activity of women changed while on ART, and cannot discern why ART is linked to increased pregnancy. By using pregnancy data gathered from patient questionnaires rather than laboratory tests, the study is limited by the possibility of inaccurate patient reporting. Understanding how pregnancy rates vary in HIV-infected women receiving ART helps support the formation of responsive, effective HIV programs. Female HIV patients of child-bearing age, who form the majority of patients receiving ART in sub-Saharan Africa, would benefit from programs that combine starting HIV treatment with ART with education and contraception counseling and pregnancy-related care.

Objective(s): Few data are available from resource-limited countries on long-term outcomes of HIV-infected women who initiate antiretroviral therapy (ART) during pregnancy. Design: Analysis of data from adult patients enrolled in the MTCT-Plus Initiative who initiated ART between 2003 and 2006 in seven countries in Sub-Saharan Africa and Thailand. Methods: Mean population changes were assessed and multivariable mixed linear regression modeling was used to examine covariate effects on differences in absolute CD4 + cell count responses. Kaplan-Meier methods were used to examine program retention combining survival and losses to follow-up. Results: Of 2229 individuals initiating ART, 1688 were women, of which 605 were pregnant (median gestational age 7 months), 1083 were not pregnant, and 541 were men. The average CD4 + response by 30 months on ART was 451 cells/μl among women who were pregnant at ART initiation as compared with 435 cells/μl among nonpregnant women (P=0.53) and 349cells/μl among men (P

Medication adherence is critical for children’s HIV treatment success, but obtaining accurate assessments is challenging when complex measurement technologies are not feasible. Our goal was to evaluate a multidimensional adherence interview designed to improve upon existing adherence measures. Data from caregivers (N = 126) of perinatally infected children were analyzed to determine the ability of the revised interview guide to detect potential treatment non-adherence. Questions related to viral load (VL) on a bivariate level included proportion of doses taken in the previous 3 days and 6 months, caregivers’ knowledge of prescribed dosing frequencies, and caregivers’ reports of problems associated with medication administration. VL was not associated with 3-day recall of missed doses. In multivariate analyses, only caregiver knowledge of prescribed dosing frequencies was uniquely associated with VL. Our modified interview appears to successfully identify family struggles with adherence and to have the capacity to help clinicians address medication adherence challenges.

OBJECTIVES: The difficulties diagnosing infants and children with HIV infection have been cited as barriers to increasing the number of children receiving antiretroviral therapy worldwide. Design: We implemented routine HIV antibody counseling and testing for pediatric patients hospitalized at the University Teaching Hospital a national reference center in Lusaka Zambia. We also introduced HIV DNA polymerase chain reaction (PCR) testing for early infant diagnosis. METHODS: Caregivers/parents of children admitted to the hospital wards were routinely offered HIV counseling and testing for their children. HIV antibody positive (HIV+) children

BACKGROUND: To date, an estimated 10% of children eligible for antiretroviral treatment (ART) receive it, and the frequency of retention in programs is unknown. We evaluated the 2-year risks of death and loss to follow-up (LTFU) of children after ART initiation in a multicenter study in sub-Saharan Africa. METHODS: Pooled analysis of routine individual data from 16 participating clinics produced overall Kaplan-Meier estimates of the probabilities of death or LTFU after ART initiation. Risk factors analysis used Weibull regression, accounting for between-cohort heterogeneity. RESULTS: The median age of 2405 children at ART initiation was 4.9 years (12%, younger than 12 months), 52% were male, 70% had severe immunodeficiency, and 59% started ART with a nonnucleoside reverse transcriptase inhibitor. The 2-year risk of death after ART initiation was 6.9% (95% confidence interval [CI]: 5.9 to 8.1), independently associated with baseline severe anemia (adjusted hazard ratio [aHR]: 4.10 [CI: 2.36 to 7.13]), immunodeficiency (adjusted aHR: 2.95 [CI: 1.49 to 5.82]), and severe clinical status (adjusted aHR: 3.64 [CI: 1.95 to 6.81]); the 2-year risk of LTFU was 10.3% (CI: 8.9 to 11.9), higher in children with severe clinical status. CONCLUSIONS: Once on treatment, the 2-year risk of death is low but the LTFU risk is substantial. ART is still mainly initiated at advanced disease stage in African children, reinforcing the need for early HIV diagnosis, early initiation of ART, and procedures to increase program retention.

Objective To determine factors associated with prenatal HIV testing in women who accepted rapid testing at delivery. Methods The mother–infant rapid intervention at delivery (MIRIAD) protocol offered counseling and voluntary HIV testing in six US cities including New York City (NYC). These hospitals are required to document the HIV status of pregnant women or their infants. From January 2002 to January 2005, 653 HIV-negative women were interviewed post-partum. Results 63% of women reported prior HIV testing during the index pregnancy, although their results were not available at delivery. Multivariate logistic modeling identified receipt of prenatal care and delivery in NYC as being associated with having been offered prenatal HIV testing. In a model restricted to women receiving medical care, emergency department (ED) use and delivery outside of NYC were associated with not having been offered testing. In a model restricted to women who were offered prenatal testing, acceptance was associated with delivery outside of NYC. Conclusions Improved documentation of prenatal test results, expanded prenatal testing in non-traditional settings like EDs, and routine voluntary “opt-out” testing during pregnancy may further reduce perinatal HIV transmission.

BACKGROUND Protease inhibitor (PI)-containing regimens have led to improved survival among HIV-infected children. However, adverse effects, including dyslipidemia, may put children at risk for cardiovascular disease. METHODS Serum cholesterol and triglyceride levels were recorded on perinatally HIV-infected children participating in the PACTS-HOPE cohort (1999-2004). Hypercholesterolemia (HC) was defined as cholesterol > or =200 mg/dL and hypertriglyceridemia (HT) as triglycerides >or =150 mg/dL. HC and HT were modeled over time using generalized estimating equations. RESULTS For 178 children, 47% met criteria for HC and 67% for HT at least once during the study period. In generalized estimating equation models, PI use, undetectable viral load, and immunologic category 3 were independent predictors of HC. HT was significantly associated with PI use and body mass index (BMI) > or =90th percentile for age and gender. Among children on PI-containing regimens, HC was significantly associated with multiple PIs and undetectable viral load; HT was predicted by body mass index > or =90th percentile and ritonavir use. The prevalence of clinical lipodystrophy was 5.6% (10/178). CONCLUSIONS Children on PI-containing regimens have a higher risk of both HC and HT. Lipid levels should be measured regularly in children on antiretroviral treatment. Interventions such as diet, exercise, or lipid-lowering drug therapy may benefit some children.

Objective To determine the relationship of maternal health factors and infant antiretroviral treatment to the risk of pediatric disease progression to AIDS or death by 24 months of age. Design Prospective perinatal HIV-1 transmission and pediatric natural history study. Setting Urban medical centers in four cities in the USA. Participants A total of 2656 pregnant and postpartum HIV-infected women enrolled in the Perinatal AIDS Collaborative Transmission Study (PACTS) and 360 children determined to be HIV-infected. Main outcome measures Pediatric AIDS or death by 24 months of age. Results Children born to mothers with class C disease, CD4 cell count 100 000 copies/ml progressed more rapidly than children born to mothers with less advanced disease. In a multivariate analysis, there was an increased risk of progression if mothers had Class C disease [relative risk (RR), 1.7; 95% confidence interval (CI), 1.0-2.7] or HIV-1 RNA > 100 000 copies/ml (RR, 2.4; 95% CI, 1.2-4.6) controlling for child antiretroviral therapy and year of birth. Earlier years of birth significantly increased the likelihood of rapid progression (P = 0.01) in this multivariate model. Children who received combination antiretroviral therapies with a protease inhibitor or non-nucleoside reverse transcriptase inhibitor were significantly less likely to progress compared with those receiving no therapy (P = 0.03). Conclusions HIV-1-infected infants born to women with advanced HIV-1 disease were at increased risk for rapid disease progression. More recent birth year and early treatment with potent antiretroviral therapy significantly diminished the likelihood of developing AIDS or dying during early childhood.

Injection drug users (IDUs) account for more than 60% of all new hepatitis C virus (HCV) infections in the United States.1,2 Fifty to eighty percent of new IDUs are infected within 6 to 12 months of initial injection.3 Current treatment regimens are not highly effective, and no vaccine against HCV is available.1,4–7 Studies suggest that drug treatment and syringe exchange programs may play a role in reducing HCV infection among participants by promoting drug abstinence or safer injection practices among those who continue to use drugs.3,8–12 The New York City Department of Health conducted a survey of local drug treatment and syringe exchange programs to determine whether their HCV screening and counseling practices were carried out, as recommended in recent federal guidelines.1

We studied decisions to continue or terminate pregnancy among human immunodeficiency virus (HIV)-seropositive ( + ) and -seronegative (-) intravenous drug users informed of HIV antibody status before 24 weeks' gestation. Fourteen (50%) of 28 HIV+ vs 16 (44%) of 36 HIV- women chose to terminate their pregnancies. In retrospective interviews, HIV + women were more likely to have perceived their risk of perinatal HIV transmission to be greater than or equal to 50% and, among those who terminated pregnancy, to cite this concern as an important factor in their decision. However, decisions to terminate pregnancy were predicted more readily by pregnancy-related variables such as prior elective abortion, a negative emotional reaction to pregnancy, and whether the pregnancy had been unplanned. Women who were HIV + and chose to continue their pregnancies cited the desire for a child, religious beliefs, and family pressure as the most important factors in their decisions. Results indicate that while concerns about perinatal transmission of HIV may lead to decisions to terminate pregnancy in certain cases, there may be other determinants of pregnancy decisions in this population. Counseling of HIV-infected women must address not only perinatal transmission but also the sociocultural and behavioral context in which pregnancy decision making takes place.
