BackgroundUnderstanding the absolute and relative risk of human immunodeficiency virus type 1 (HIV) acquisition during pregnancy and the postpartum period can inform HIV prevention strategies for women.MethodsWe used a complementary log-log model and data from 2751 HIV-serodiscordant couples to compare the probability of HIV acquisition among women per sex act during early pregnancy, late pregnancy, the postpartum period, and the nonpregnant period.ResultsAt total of 686 pregnancies were identified, and 82 incident HIV infections occurred. After adjustment for condom use, age, preexposure prophylaxis (PrEP) use, and HIV viral load, the per-act probability of HIV acquisition was higher in late pregnancy (adjusted relative risk [aRR], 2.82; P = .01) and the postpartum period (aRR, 3.97; P = .01) as compared to that during nonpregnant period. For a 25-year-old woman not taking PrEP, the HIV acquisition probability per condomless sex act with an HIV-infected male partner with a viral load of 10 000 copies/mL was 0.0011 (95% confidence interval [CI] 0.005-0.0019), 0.0022 (95% CI, 0.0004-0.0093), 0.0030 (95% CI, 0.0007-0.0108), and 0.0042 (95% CI, 0.0007-0.0177) during the nonpregnant period, early pregnancy, late pregnancy, and the postpartum period, respectively.ConclusionThe HIV acquisition probability per condomless sex act steadily increased during pregnancy and was highest during the postpartum period, suggesting that biological changes during pregnancy and the postpartum period increase HIV susceptibility among women.

Introduction: High maternal HIV incidence contributes substantially to mother-to-child HIV transmission (MTCT) in some settings. Since 2006, HIV retesting during the third trimester and breastfeeding has been recommended by the World Health Organization in higher prevalence ([greater than or equal to]5%) settings to reduce MTCT. However, many countries lack clarity on when and how often to retest pregnant and postpartum women to optimize resources and service delivery. We reviewed and characterized national guidelines on maternal retesting based on timing and frequency. Methods: We identified 52 countries to represent variations in HIV prevalence, geography, and MTCT priority and searched available national MTCT, HIV testing and HIV treatment policies published between 2007 and 2017 for recommendations on retesting during pregnancy, labour/delivery and postpartum. Recommended retesting frequency and timing was extracted. Country HIV prevalence was classified as: very low (5 to Results and discussion: Overall, policies from 49 countries were identified; 51% from 2015 or later and most (n = 25) were from Africa. Four countries were high HIV prevalence, seven intermediate, sixteen low and twenty-two very low. Most (n = 31) had guidance on universal voluntary opt-out HIV testing at the first antenatal care (ANC) visit. Beyond the first ANC visit, the majority (78%, n = 38) had guidance on retesting; 22 recommended retesting all women with unknown/negative status, five only if unknown HIV status, three in pregnancy based on risk and eight combining these approaches. Retesting was universally recommended during pregnancy, labour/delivery and postpartum for all high prevalence settings and four of seven intermediate prevalence settings. Five UNAIDS priority countries for EMTCT with low/very low HIV prevalence, but high/intermediate MTCT, had no guidance on retesting. Conclusions: Retesting guidelines for pregnant and postpartum women were ubiquitous in high prevalence countries and defined in some intermediate prevalence countries, but absent in some low HIV prevalence countries with high MTCT. Countries may require additional guidance on how to optimize maternal HIV testing and whether to prioritize retesting efforts or discontinue universal retesting based on HIV incidence. Research is needed to assess country-level guideline implementation and impact.

Awareness of HIV status in Malawi is 88.3% and lowest among 15–24-year-olds (76.2%). There is a need to understand HIV testing history and transmission in this age group. We analyzed pooled HIV surveillance data to describe testing history and HIV recent infection among 8,389 HIV-positive 15–24-year-olds from 251 sites in Malawi between 2019 and 2022. Most HIV-positive 15–24-year-olds were female; aged 23–24 years; rural residents; and diagnosed at voluntary counseling and testing. No prior HIV testing was reported in 43.5% and 32.9% of 15–19-year-olds and males, respectively. Overall, 4.9% of HIV-positive diagnoses were classified as recent HIV infections, with the highest proportions among breastfeeding women (8.2%); persons tested at sexually transmitted infection clinics (9.0%); persons with a prior negative test within 6 months (13.0%); and 17–18-year-olds (7.3%). Tailored and innovative HIV prevention and testing strategies for young adolescents, young males, and pregnant and breastfeeding women are needed for HIV epidemic control. [ABSTRACT FROM AUTHOR]

1. Introduction The adoption of VoIP has increased both locally and internationally in recent years. This increased rate of adoption is largely due to the value a VoIP implementation may [...], Since the deregulation of Voice over Internet Protocol (VoIP) in 2005, many South African organizations are now attempting to leverage its cost saving and competitive values. However it has been recently cited that VoIP is one of the greatest new risks to business. This risk is cited to increase Information Security insurance premiums in the near future. Due to the dynamic nature of the technology, regulatory and legislative concerns such as lawful interception of communications and privacy may also contribute to business risk. VoIP consists of both direct communications (voice conversation) and indirect communications (voice mails, emails and instant messaging). Due to this dual nature, complying with regulations such as the Regulation of Interception of Communications and Provision of Communication-Related Information Act (RICA) should be considered. In order to leverage value from the VoIP implementation, an executive or SME owner should look to implement the technology with knowledge of the potential risk of civil liability. This is further highlighted by the King III Report which makes the Directors and CEO of an organisation ultimately responsible for IT Governance and Information Security Governance. The report goes further to say, any new technology, such as VoIP, should comply with all South African legislation and regulations. This responsibility encourages the practice of both due care and due diligence. However, recent trends exercised by Information Security professionals, responsible for drafting Information Security policies, often neglect the regulatory requirements and choose to only implement international best practices with no considerations to the risk of civil liability. Although these best practice frameworks may inadvertently comply with existing local legislation, a chance of an oversight is a possibility. Oversights may not only result in criminal sanctions but also civil action due to losses or damages suffered by a third party. Using both the identified regulations and relevant international best practices one may attempt to ensure good Governance with regards to VoIP's dual nature. The aim is to aid executives and SME owners in mitigating the risk of civil liability to better leverage VoIP's value by utilizing the proposed VoIP: Civil Liability Risk Table. This should aid in the exercise of due care and due diligence when implementing VoIP as a means of conducting business communication.

Introduction: HIV testing is key to the delivery of pre-exposure prophylaxis (PrEP): testing HIV-uninfected at-risk persons is the first step for PrEP initiation and ongoing HIV testing is an essential part of PrEP delivery. Thus, novel and cost- effective HIV-testing approaches to streamline delivery of PrEP are urgently needed. Within a demonstration project of PrEP for HIV prevention among high-risk HIV serodiscordant couples in Kenya (the Partners Demonstration Project), we conducted a pilot evaluation of HIV self-testing. Methods: Clinic visits were scheduled quarterly and included in-clinic HIV testing using fingerstick rapid HIV tests and refills of PrEP prescriptions. HIV oral fluid self-test kits were provided for participants to use in the two-month interval between scheduled quarterly clinic visits. Acceptability of HIV self-testing was assessed using both quantitative and qualitative methods. Results: We found that 222 of 226 (98%) HIV-uninfected persons who were offered accepted self-testing. Nearly all (96.8%) reported that using the self-testing kit was easy. More than half (54.5%) reportedly did not share the HIV results from selftesting with anyone and almost all (98.7%) the participants did not share the HIV self-testing kits with anyone. Many participants reported that HIV self-testing was empowering and reduced anxiety associated with waiting between clinic HIV tests. Conclusions: HIV self-testing was highly acceptable and may therefore be a feasible strategy to efficiently permit routine HIV testing between PrEP refills.
