Transfusion transmissible infections (TTIs), caused by hepatitis B virus (HBV), human immunode-ficiency virus (HIV), hepatitis C virus (HCV), and syphilis, have a high global impact, especially in sub-Saharan Africa. We evaluated the trend of these infections over time in blood donors in Angola. A retrospective cross-sectional study was conducted among blood donors in Angola from 2005 to 2020. Additionally, frozen samples obtained from blood donors in 2007 were investigated to identify chronic HCV carriers and possible occult HBV infection (OBI). The overall prevalence of HBV, HCV, HIV, and syphilis was 8.5, 3, 2.1, and 4.4%, respectively, among 57,979 blood donors. HBV was predominant among male donors, while the remaining TTIs were predominant among women. Donors >50 years had a significantly high prevalence for all TTIs. Chronic HCV infection was ab-sent in 500 samples tested and OBI was present in 3%. Our results show the continued high prev-alence of TTIs among blood donors in Angola. Most infections showed a significantly low preva-lence in years with campaigns seeking voluntary blood donors, thus, reinforcing the importance of this type of donor to ensure safe blood. Africa, with a high prevalence of diverse pathogens, should consider cost-effective pathogen reduction technologies, once they are commercially accessible, to increase the availability of safe blood.

Anemia among adolescent females is a major worldwide public health problem which should be given appropriate attention. Half of all anemic cases are caused by iron deficiency. In addition to anemia, poor nutrition is also a challenge in sub-Saharan Africa. This study determined the prevalence of anemia and undernutrition among adolescent females in school. A cross-sectional study was conducted among 151 adolescent females in four basic schools in the Ahafo region of Ghana. The hemoglobin level and anthropometry measures of participants were taken to determine their anemic and nutritional status. The prevalence of anemia among adolescent females in school was 50.3%. Out of the 151 participants, 6.6%, 19.9%, and 23.8% were severely anemic, moderately anemic, or mildly anemic, respectively. Only 2% of the participants were underweight, but the rate of stunting was 26.5%. The notable high prevalence of anemia that was found among adolescent females was correlated with other health and wellness concerns. Anemia and under nutrition negatively affect academic performance, productivity, and general wellbeing of adolescents; therefore, effective measures should be put in place to correct and eradicate these nutritional problems.

The prevalence of stunting among children in Uganda and Sub-Saharan Africa is still high, and if Uganda is to achieve the food-related Sustainable Development Goals (SDGs), it must urgently invest in improving nutrition and sanitation. In a food rich area like Bushenyi, chronic undernutrition could be due to several other factors than mere scarcity of food. The Objective(s). This study was carried out to determine the prevalence and socioclinical factors responsible for chronic undernutrition (stunting) among preschool children aged 1–5 years in selected Health facilities in Bushenyi district. Methodology. This was a cross-sectional study assessing the prevalence of stunting and its associated factors among children aged 1–5 years attending selected health centers in Bushenyi District. Data was collected using a pretested questionnaire, taking anthropometric measurements (height/length), and stool analysis for eggs of soil-transmitted helminthes. Prevalence of stunting was presented as percentages. Logistic regression with adjusted prevalence ratio was performed to test the association between the sociodemographic and clinical factors and stunting at bivariate levels of analysis. Results. Most of the children were female, with a median age of 2.1 years and resided in semiurban areas of Bushenyi with their parents. Prevalence of stunting was 89.3%. Only 10.7% of the children were infested with soil-transmitted helminthes. Children likely to be stunted were those who drank unboiled water and were exclusively breastfed. Conclusion. There is a high prevalence of chronic malnutrition in Bushenyi district associated with parents’/care takers’ low level of knowledge.

En Afrique subsaharienne, les infections transmissibles par la transfusion sanguine comme la syphilis sont très répandues, avec une prévalence pouvant atteindre 25% chez les donneurs de sang. La présente étude avait pour objectif de déterminer la prévalence de la syphilis chez les donneurs de sang au niveau de la Banque du Sang d’Abéché. Nous avons mené une étude transversale à visée descriptive, qui s’est déroulée de mai à août 2017. Les échantillons de sang des donneurs ont été testés par immunochromatographie pour la détection des anticorps anti-tréponémiques (Biomnis®). Sur 789 donneurs de sang inclus dans l’étude, la prévalence de la syphilis était de 4,9 %. Les donneurs étaient à 96,1% de sexe masculin et 3,9% de sexe féminin. Cette prévalence était plus élevée chez les sujets âgés de [21-30] ans, chez les femmes, les donneurs non scolarisés, divorcés et les domestiques/ménagères habitant la zone d’Abéché urbaine. Ces résultats montrent qu’il est nécessaire de mettre en place une politique de suivi et de prise en charge médicale des donneurs de sang atteints de la syphilis.Mots clés: Transfusion sanguine, receveurs, Treponema pallidum, don de sang.   English Title: Prevalence of syphilis in blood donors at Abéché blood bank in ChadIn sub-Saharan Africa, infections transmitted by blood transfusion such as syphilis are widespread, with prevalence up to 25% in blood donors. The purpose of this study was to determine the prevalence of syphilis in blood donors at the Blood Bank of Abéché. It was a descriptive cross-sectional study, which ran from May to August 2017. Donor blood samples were tested by immunochromatography for the detection of anti-treponemal antibodies (Biomnis®). Of the 789 blood donors included in the study, the prevalence of syphilis was 4.9%. Donors were 96.1% male and 3.9% female. This prevalence was higher in subjects aged [21-30] years, women, out-of-school, divorced and domestic / household donors living in the urban Abéché area.

Blood safety remains a challenge to many countries in sub-Saharan Africa including Ghana due to poorly planned blood donation exercises in the various communities. Blood and its products usual-ly come from two main sources; voluntary non-remunerated donors (VNRD) and family replace-ment donors (FRD). In Ghana, and in many developing countries, FRDs seem to be the major source of blood supply whilst in developed countries VNRDs are the major source. This study de-termined and compared the prevalence of four transfusion transmissible infections (TTIs); HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and Treponema palladium (TP) among FRDs and VNRDs at the Komfo Anokye Teaching Hospital to compare the safety of blood from these two groups. This cross-sectional study was undertaken at the transfusion medicine unit (TMU) of the Komfo Anokye Teaching Hospital between March and May 2014. A total of 400 blood donors (200 FRDs and 200 VNRDs) were enrolled in this study after obtaining written informed consent. Blood samples from each of the donors were then tested for HIV, hepatitis B and C, and syphilis using rapid test kits. ABO and Rhesus blood groups were also determined for all the samples. Prev-alence of TTIs was higher among FRDs (23.5%) than in VNRDs (3.5%) with males (47) been more infected than females (7). Age group 21- 30 years was the most infected, followed by age groups 31- 40 years, 11- 20 years, 41- 50 years and 51- 60 years respectively. FRDs among the younger age group, 17- 30 years, were also more infected than their VNRD counterparts. Repeat blood donors among the VNRD group, were found to be safer than their first-time counterparts. Overall, TTIs were significantly higher in the FRD group than in the VNRD group. The prevalence rates of all the infections tested were higher in the FRD group compared to the VNRD group. FRDs were the higher risk population for TTIs in comparison to VNRDs. VNRDs should therefore be encouraged to donate blood regularly.Keywords: Transfusion Transmissible Infections, HBsAg, HCV, HIV, Treponema pallidum

Aims: Provision of constant and safe blood has been a public health challenge in Sub-Saharan Africa with a high prevalence of transfusion-transmissible infections (TTIs). This study aimed at determining the seroprevalence of the Human Immunodeficiency Virus (HIV) among prospective blood donors at two Hospitals (government and private-owned) in Rivers State, and also to relate some demographic studies to the screening results. Study Design:  Cross-sectional study. Place and Duration of Study: Two Hospitals (a government-owned and private-owned) in Rivers State, Nigeria, between January 2018 and April 2019. Methodology: Two hundred and eighty-two (185 males and 97 females) blood donors were recruited for this study. Sera samples were screened for antibodies to HIV-1 and -2 using enzyme-linked immunosorbent assay (ELISA) based kits following the manufacturer’s description. Results: Of the 282 screened prospective donors (males and females) in this study, the overall prevalence of HIV from both hospitals was 6.0% with a seronegativity of 94.0%. There was a significant relationship (p <0.05) between the overall seroprevalence of HIV concerning gender (p-0.006) all other demographics had no significant association with HIV. Age group 21-30 had the highest prevalence of HIV (53.80%). Donors with tertiary education had the highest prevalence rate (52.90%) of HIV. About marital status, the unmarried donors had higher HIV prevalence (64.70%) when compared with the married donors (35.30%). However, family donors had the highest prevalence of HIV (52.90%). Finally, concerning occupation, students had a higher HIV prevalence (47.10%). Conclusion: The seroprevalence of HIV in Port Harcourt, Rivers State, Nigeria was high. This shows that HIV remains a threat to safe blood transfusion and public health in Nigeria. Strict adherence to selection criteria and algorithm of donor screening is hereby advocated.

Abstract Background Consistent use of insecticide-treated nets (ITNs) and intermittent preventive treatment in pregnancy (IPTp) have been recommended as cost-effective interventions for malaria prevention during pregnancy in endemic areas. However, the coverage of these interventions during pregnancy in sub-Saharan Africa is still suboptimal. In this study, we investigated the uptake of IPTp and ITNs, and associated factors among women during their recent pregnancy in Eastern Uganda. Methods This was a cross-sectional study conducted among 2,062 women who had delivered within the last 12 months in three districts in Eastern Uganda. The primary outcomes were consistent ITN use and optimal uptake (at least 3 doses) of IPTp. A modified Poisson regression was used to examine the association between consistent ITN use and the uptake of optimal doses of IPTp with independent variables. Data were analyzed using Stata 14 software. Results The level of uptake of IPTp3 (at least three doses) was 14.7 %, while IPTp2 (at least two doses) was 60.0%. The majority (86.4%) of mothers reported regularly sleeping under mosquito nets for the full duration of pregnancy. Uptake of IPTp3 was associated with engaging in farming (adjusted PR = 1.71, 95% CI [1.28 – 2.28]) or business (adjusted PR = 1.60, 95% CI [1.05 – 2.44]), and attending at least 4 antenatal care (ANC) visits (adjusted PR = 1.72, 95%CI [1.34 – 2.22]). On the other hand, consistent ITN use was associated with belonging to the fourth wealth quintile (adjusted PR = 1.08, 95% CI [1.02 – 1.14]) or fifth wealth quintile (adjusted PR = 1.08, 95% CI [1.02- 1.15]), and attending at least 4 ANC visits (adjusted PR = 1.07, 95% CI [1.03- 1.11]). Conclusion Uptake of IPTp3 and consistent ITN use during pregnancy were lower than recommended guidelines, thus threatening the progress so far made towards malaria elimination. Our findings highlight the need for more efforts to enhance utilisation of ANC services, which is likely to increase the uptake of these two key malaria preventive measures during pregnancy.

Introduction: We aimed to evaluate the prevalence of "anti-HBc alone" among Syrian blood donors, highlighting the possibility of representing occult HBV infection. Methodology: Sera of 3,896 healthy blood donors were tested for both HBsAg and anti-HBc. HBsAg-negative, anti-HBc-positive samples were further tested for the antibodies to HBsAg (anti-HBs), and "anti-HBc alone" sera were tested for HBV DNA. Results: Of 3,830 HBsAg-negative donors, 63 were "anti-HBc alone" donors, five of whom were HBV DNA positive. Conclusions: Greater consideration should be given to the "anti-HBc alone" serological profile in blood screening, premarital testing, organ transplantation tests, and other HBV transmission-related procedures in Syria.
