Rubella is a mild, contagious viral infection that is endemic worldwide and poses a serious threat to infants and pregnant women. It causes a spectrum of severe birth defects like congenital rubella syndrome, abortions and still birth if the infection occurs within the first trimester of pregnancy. The Seroprevalence of rubella IgG antibodies was investigated among 187 pregnant women attending Mile Four Hospital (MFH) Abakaliki, Ebonyi State. Blood specimens were collected from the subjects and sera extracted. The sera were screened for rubella virus immunoglobulin G antibody (IgG) using ELISA test Kit (Micro Immune limited, UK). The results obtained were subjected to SPSS system and Chi square test for significant difference at 95% confidence interval. Of the 187 pregnant women tested, 174(93.05 %) were positive for the rubella virus IgG. This study revealed that all the subjects who were 41 years and above tested positive 5(100.00%), whereas those who were 15 years and below 2 subjects had the prevalence rate of 50.00%. Pregnant women in their third, first and second trimesters had prevalence rates of 95.75%, (95.35%) and 86.95% accordingly. Samples tested shows that unmarried women were more infected with anti- rubella IgG of 94.44% recorded, then followed by married women with 93.79% and divorcee had 90.91%. However, widows had the least prevalence rate of 84.62%. Occupationally, women civil servants had prevalence rate of 97.56%. Educationally, pregnant women with tertiary education were more infected, rubella virus amounting to 96.61%. More infection was found among women living in rural areas with 93.59% rate, than their urban counterparts who had 92.66%. Furthermore, primigravida women were more infected (95.16%). The Sero-prevalence of rubella in this study was high and it calls for general surveillance and mass immunization of children and females of child bearing age.

The clinical and public health implication of HIV Western blot (WB) indeterminate results is yet to be appraised in sub-Saharan Africa, including Nigeria. Using HIV Tri Line Test enzyme-linked immunosorbent assay (ELISA), 1286 patients (600 males and 686 females; age range, 5-60 years) with symptoms suggestive of HIV infection were screened. A total of 1020 (79.3%, 95% confidence interval [CI] 76.8-81.5) of the patients comprising of 514 (85.7%) males and 506 (73.8%) females were HIV seropositive and the difference was statistical significantly ([X.sup.2] = 5.72, df = 1, p < 0.05). Western blot analysis of sera from the 1020 HIV-seropositve individuals using the BIO-RAD NEW LAV-BLOT I specifying World Health Organization (WHO) interpretive criteria, confirmed the HIV serostatus of 815 (79.9%, 95% CI, 77.4-82.4) of them with 205 (20.1%, 95% CI, 17.6-22.6) individuals having indeterminate results consisting of either; I env [+ or -] gag [+ or =] pol, gag + pol, gag only or pol only. Of these, 102 (19.8%) were males and 103 (20.4%) were females. Patients aged 11-20 years old recorded the highest percentage of indeterminate results (31.7%, 95% CI, 20.2-43.2) while those aged 21-30 years recorded the least (14.2%, 95% CI, 10.6-17.8) and the difference was statistically significant ([X.sup.2] = 15.73, df = 5, p < 0.05). Result confirmed the limitation of Western blot assays in HIV confirmatory serodiagnosis. After obtaining HIV indeterminate Western blot result, clinicians should consider the total profile for the patient, reassess risk factors for HIV infection, perform a HIV retesting at 3-month intervals for 6 months or use an alternate HIV antibody confirmatory assay and running antibody tests for other human retroviruses.

The first 140 days of pregnancy are critical as regards rubella virus infection because of the likelihood of a poor pregnancy outcome. This study was undertaken to investigate the likelihood of exposure to poor pregnancy outcomes due to seroprevalence of rubella among selected pregnant women attending Mile Four Hospital, Abakaliki, Ebonyi State, Nigeria. The seroprevalence of rubella immunoglobulin M (IgM) antibodies was investigated among pregnant women. A total of 187 sera samples collected from the women were screened for rubella virus IgM antibody using the enzyme-linked immunosorbent assay (ELISA). The results obtained were analyzed using SPSS. The chi square test was performed at a P value of 0.05 significance and at a 95% confidence interval. Of the 187 pregnant women, 35 (18.72%) were positive for the rubella virus. Pregnant women within 26–30 years of age had the highest prevalence (26.15%), while those aged 35–40 years had the least prevalence. Married women had the highest prevalence (20.0%), followed by singles (16.67%) and widows (15.38%), while divorced pregnant women recorded the least prevalence (9.20%). Pregnant women with no formal education were more predisposed to rubella virus (22.22%) infection compared to their educated counterparts. Occupationally, full-time housewives had the highest prevalence (24.26%). The infection rates seemed to wane as pregnancy advanced. The first trimester had the highest prevalence (21.88%), followed by the second trimester (18.84%) and the third trimester (17.44%). Pregnant women living in urban areas had higher IgM seroprevalence (20.18%) than those in rural areas (16.67%). Furthermore, grand multigravidas were more infected (22.73%) than primigravidas (14.52%) and multigravidas (20.39%). The seroprevalence of rubella in this study was high, and it calls for general surveillance and mass immunization of children and females of childbearing age in the area to help reduce the incidence of congenital rubella syndrome.

Human herpesvirus 4 which is commonly known as Epstein-Barr virus (EBV) is one of the opportunistic pathogens that affect human immunodeficiency virus (HIV) infected individuals and it is the leading cause of death and cancer in humans. The study was designed to evaluate the prevalence of EBV among HIV-1 infected individuals in Abakaliki metropolis, Ebonyi State, Nigeria. A total of 91 HIV-1 infected individuals were collected from Mile 4 Hospital, Abakaliki, Ebonyi State, Nigeria. ELISA was used to determine the Epstein-Barr Nuclear Antigen (EBNA) IgG and IgM antibodies. Full blood count (FBC), white cell count (WBC) and differential counts were also determined using standard hematological methods. Of the 91 serum samples obtained from HIV-1 infected individuals, 87(95.6%) and 20(22.0%) samples were found to be positive for EBVNA IgG and IgM antibody respectively. All the age groups had significant IgG prevalence, but age groups ≤ 20 years, and ≥ 41 had the highest prevalence while age group 21–30 years was found to have a less rate of prevalence. Also, the highest seropositivity for IgM antibodies was observed in the age group 31–40 years (32.4%) while the age groups ≤20 years (0.0%) is the lowest. However, these differences were not statistically associated with PVL and EBVNA IgG (p =.4311) and IgM antibodies (p =.4861).Higher seropositivity of EBVNA IgG occurred among those with PVL 41–10,000 copies/mL (100.0%) and PVL 10,001 copies/mL and above (100.0%) compared to those with PVL less than or equal to 40 copies/mL (95.0%). While regarding EBVNA IgM antibodies, higher seropositivity of EBVNA IgM occurred among those with PVL less than or equal to 40 copies/mL (25.0%) compared to those with PVL 41–10,000 copies/mL (20.0%) and PVL 10,001 copies/mL and above (8.3%). There was a significant difference in Neutrophils p <.026 between the mean of females and males (40.9 ± 11.7 and 36 ± 31.1) infected with EBV IgM in HIV individuals. There was also a significant positive correlation between CD4 counts and the WBC, Lymphocytes, Eosinophils and the neutrophil among the HIV-1 individuals used for this study. The correlations observed between both CD4+ count and neutrophil support the potential use of neutrophils as a marker of EBV in HIV disease progression and as useful markers of immune activation.

Background: The lack of effective use of research evidence in policy-making is a major challenge in most low- and middle-income countries (LMICs). There is need to package research data into effective policy tools that will help policy-makers to make evidence-informed policy regarding infectious diseases of poverty (IDP). The objective of this study was to assess the usefulness of training workshops and mentoring to enhance the capacity of Nigerian health policy-makers to develop evidence-informed policy brief on the control of IDP. Methods: A modified "before and after" intervention study design was used in which outcomes were measured on the target participants both before the intervention is implemented and after. A 4-point Likert scale according to the degree of adequacy; 1 = "grossly inadequate," 4 = "very adequate" was employed. The main parameter measured was participants' perceptions of their own knowledge/understanding. This study was conducted at subnational level and the participants were the career health policy-makers drawn from Ebonyi State in the South-Eastern Nigeria. A oneday evidence-to-policy workshop was organized to enhance the participants' capacity to develop evidence-informed policy brief on IDP in Ebonyi State. Topics covered included collaborative initiative; preparation and use of policy briefs; policy dialogue; ethics in health policy-making; and health policy and politics. Results: The preworkshop mean of knowledge and capacity ranged from 2.49-3.03, while the postworkshop mean ranged from 3.42-3.78 on 4-point scale. The percentage increase in mean of knowledge and capacity at the end of the workshop ranged from 20.10%-45%. Participants were divided into 3 IDP mentorship groups (malaria, schistosomiasis, lymphatic filariasis [LF]) and were mentored to identify potential policy options/recommendations for control of the diseases for the policy briefs. These policy options were subjected to research evidence synthesis by each group to identify the options that have the support of research evidence (mostly systematic reviews) from PubMed, Cochrane database and Google Scholar. After the evidence synthesis, five policy options were selected out of 13 for malaria, 3 out of 10 for schistosomiasis and 5 out of 11 for LF. Conclusion: The outcome suggests that an evidence-to-policy capacity enhancement workshop combined with a mentorship programme can improve policy-makers' capacity for evidence-informed policy-making (EIP).

Background: In Nigeria, malaria, schistosomiasis and lymphatic filariasis are among infectious diseases of poverty (IDP) with severe health burden and require effective policy strategies for their control. In this study, we investigated the value of policy brief and policy dialogue as excellent policymaking mechanisms that enable policymakers to adapt effective evidence informed policy for IDP control. Methods: A policy brief was developed on the control of malaria, schistosomiasis and lymphatic filariasis and subjected to deliberations in a one-day multistakeholder policy dialogue held in Ebonyi State Nigeria. A modified cross sectional intervention study design was used in this investigation. Structured pretested questionnaires were used to evaluate the policy brief document and policy dialogue process at the end of the policy dialogue. Results: Forty-seven policymakers participated in the dialogue. An analysis of the response on the policy brief regarding context, different features of the problem; policy options and key implementation considerations indicated the mean ratings (MNRs) mostly ranged from 6.40-6.85 on 7 point scale. The overall assessment of the policy brief had MNR at 6.54. The analysis of the response on the policy dialogue regarding the level of priority of policy issue, opportunity to discuss different features of the problem and options for addressing the problem, and the MNRs mostly ranged from 6.50-6.82. The overall assessment of the policy dialogue had MNR at 6.72. Conclusion: Policy dialogues can allow research evidence to be considered together with views, experiences and tacit knowledge of policymakers and can enhance evidence-to-policy link.

Information and communication technology (ICT) tools are known to facilitate communication and processing of information and sharing of knowledge by electronic means. In Nigeria, the lack of adequate capacity on the use of ICT by health sector policymakers constitutes a major impediment to the uptake of research evidence into the policymaking process. The objective of this study was to improve the knowledge and capacity of policymakers to access and utilize policy relevant evidence. A modified "before and after" intervention study design was used in which outcomes were measured on the target participants both before the intervention is implemented and after. A 4-point likert scale according to the degree of adequacy; 1 = grossly inadequate, 4 = very adequate was employed. This study was conducted in Ebonyi State, south-eastern Nigeria and the participants were career health policy makers. A two-day intensive ICT training workshop was organized for policymakers who had 52 participants in attendance. Topics covered included: (i). intersectoral partnership/collaboration; (ii). Engaging ICT in evidence-informed policy making; use of ICT for evidence synthesis; (iv) capacity development on the use of computer, internet and other ICT. The pre-workshop mean of knowledge and capacity for use of ICT ranged from 2.19-3.05, while the post-workshop mean ranged from 2.67-3.67 on 4-point scale. The percentage increase in mean of knowledge and capacity at the end of the workshop ranged from 8.3%-39.1%. Findings of this study suggest that policymakers' ICT competence relevant to evidence-informed policymaking can be enhanced through training workshop. [ABSTRACT FROM AUTHOR]

Objectives: To assess the seroprevalence of herpes simplex virus (HSV) types 1 and 2 in patients infected with HIV in Nigeria., Design: Cross-sectional design from January to June 2019., Setting: Federal Teaching Hospital, Ebonyi State, Nigeria., Participants: A total of 276 patients with HIV were analysed using ELISA method for the presence of HSV-1 and HSV-2 specific IgG antibodies., Outcomes: Fisher's exact test was used to determine the association between the seroprevalence of HSV and demographic variables (statistically significant=p value ≤0.05)., Results: Totally, 212 (76.8%) and 155 (56.2%) patients with HIV were seropositive for HSV-1 and HSV-2 IgG antibodies, respectively. The seroprevalence of HSV-1 was significantly higher than the HSV-2 in patients with HIV (p value <0.0001). HSV-1 and HSV-2 seroprevalence were higher in patients aged more than 30 years. The seroprevalence of HSV-1 was significantly higher (p=0.01) in females (82.4%, 131/159) than males (69.2%, 81/117), but there was no significant difference in seroprevalence of HSV-2 in females (57.9%, 92/159) compared with males (53.8%, 63/117) (p=0.51). Professional drivers had a higher seroprevalence of HSV-1 and HSV-2 and there was a significant association between the occupation and the HSV-1 and HSV-2 seropositivity (p>0.05). The seroprevalence of HSV-1 was significantly higher in the singles (87.4%, 90/103) than the married patients with HIV (p=0.001). However, HSV-2 seroprevalence was significantly higher in the married patients with HIV (63.6%, 110/173) (p=0.001)., Conclusions: Prevalence of 76.8% for HSV-1 and 56.2% for HSV-2 among patients with HIV was seen. The HSV-1 was significantly higher in the singles while HSV-2 seroprevalence was significantly higher in the married patients with HIV with HSV-1 and HSV-2 coinfection rate of 7.6%. This study became very imperative to provide an important insight into the hidden dynamics of HSV infections., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: In Nigeria, one of the major challenges associated with evidence-to-policy link in the control of infectious diseases of poverty (IDP), is deficient information literacy knowledge and skill among policymakers. There is need for policymakers to acquire the skill to discover relevant information, accurately evaluate retrieved information and to apply it correctly., Objectives: To use information literacy tool of International Network for Availability of Scientific Publications (INASP) to enhance policymakers' knowledge and skill for policymaking on control of IDP in Nigeria., Methods: Modified "before and after" intervention study design was used in which outcomes were measured on target participants both before the intervention is implemented and after. This study was conducted in Ebonyi State, south-eastern Nigeria and participants were career health policy makers. A two-day health-policy information literacy training workshop was organized to enhance participants" information literacy capacity. Topics covered included: introduction to information literacy; defining information problem; searching for information online; evaluating information; science information; knowledge sharing interviews; and training skills., Results: A total of 52 policymakers attended the workshop. The pre-workshop mean rating (MNR) of knowledge and capacity for information literacy ranged from 2.15-2.97, while the post-workshop MNR ranged from 3.34-3.64 on 4-point scale. The percentage increase in MNR of knowledge and capacity at the end of the workshop ranged from 22.6%-55.3%., Conclusion: The results of this study suggest that through information literacy training workshop policy makers can acquire the knowledge and skill to identify, capture and share the right kind of information in the right contexts to influence relevant action or a policy decision.

Induced malaria by blood transfusion is a potential health hazard but is often neglected in many malaria endemic areas. Standard parasitological technique was used to determine the prevalence of malaria among blood donors in the South-eastern Nigeria. Of the total 325 blood donors (310 males and 15 females) screened, 133 (40.9%, CI 95%: 35.6-46.2%) were infected with malaria parasite, 78 (58.6%) had 1-10 parasites per 100 thick film fields ('+' or 4-40 parasites per mm3) while 55 (41.4%) had 11-100 parasites per 100 thick film fields ('++' or 41-400 parasites per mm3). P. falciparum was identified in all the infected cases, however 3 (2.3%) persons had mixed infection with P. malariae. Males were more infected (41.3%, CI 95%: 35.8-46.8%) than females (33.3%, CI 95%: 9.4-57.2%). The infection decreased with age with highest prevalence of 48.5% among those aged 20-25 years. The infection significantly varied with age but not with sex (P<0.05). Individuals with blood group B were slightly more infected (42.1%, 95%CI., 19.6-64.6%) than those of groups O (41.0%,CI 95%: 35.3-46.7%) and A (40.0%, CI 95%: 20.8-59.2%) but there was no significant difference (P<0.05). Highest prevalence of infection was recorded in the month of April corresponding to the onset of the wet season. An overhaul of existing blood donation policies in many health facilities in the sub-Saharan Africa to incorporate malaria screening is advocated. Curative antimalarial drugs followed by prophylactic drugs should be given to all recipients of parasitized blood.
