Female sex workers (FSWs) are considered a vulnerable population for HIV infection and a priority for HIV/AIDS response programs. This study aimed to determine HIV prevalence among FSWs in five cities in Burkina Faso. Methods. FSWs aged 18 and older were recruited using respondent driven sampling (RDS) in five cities (Ouagadougou, Bobo-Dioulasso, Koudougou, Ouahigouya, and Tenkodogo) in Burkina Faso from 2013 to 2014. HIV testing was performed using the HIV testing national algorithm. We conducted bivariate and multivariate logistic regression analysis to assess correlates of HIV in all cities combined (not RDS-adjusted). Results. Among Ouagadougou, Koudougou, and Ouahigouya FSWs, RDS-adjusted HIV prevalence was 13.5% (95% Confidence Interval [CI]: 9.6-18.7), 13.3% (95% CI: 7.6-22.4), and 13.0% (95% CI: 7.6-21.3), respectively, compared to 30.1% (95% CI: 25.5-35.1) among Bobo-Dioulasso FSWs. Factors associated with HIV infection were age (adjusted odds ratio [aOR] = 7.84 95% CI: 3.78-16.20), being married or cohabitating (aOR = 2.43, 95% CI: 1.31-4.49), and history of pregnancy (aOR = 5.24, 95% CI: 1.44-18.97). Conclusion. These results highlight the need to strengthen HIV prevention among FSWs, through behavior change strategies, and improve access to sexual and reproductive health services.

L'objectif de cette étude est d'évaluer la prévalence du virus de l'hépatite B et les facteurs qui y sont associés chez les TS dans trois villes secondaires du Burkina Faso. Matériels et méthodes : Il s'est agi d'une étude transversale dans les localités de Koudougou, Ouahigouya et Tenkodogo, trois villes secondaires du Burkina Faso. Les TS ont été recrutées de février à mai 2014 par la méthode d'échantillonnage basé sur le répondant dans le cadre d'une étude de séroprévalence du VIH. Les échantillons de sérum archivés ont été testés à la recherche de l'antigène HBs. Les données ont été analysées en utilisant le logiciel STATA version 14.0. Résultats : Au total, 320 échantillons sériques de TS ont été testés à la recherche de l'antigène HBs. Les prévalences ajustées de l'Ag HBs étaient de 6,4% (95%IC : 3,4-11,8%) à Koudougou, 15,7% (95%IC : 09,5-25,0%) à Ouahigouya et 11,0% (95%IC : 6,8-17,2%) à Tenkodogo. Les facteurs associés à l'infection étaient l'âge élevé de l'enquêtée, le nombre élevé de clients par semaine, le statut positif au VIH, la non utilisation systématique du condom. Conclusion : La prévalence de l'hépatite B et les facteurs associés dans cette étude suggèrent la nécessité de sensibiliser davantage à l'utilisation systématique du préservatif et à la vaccination contre le VHB chez les populations à haut risque, telles que les professionnelles du sexe. Mots clés : VHB, Ag HBs, travailleuses du sexe, Burkina Faso.

Although prematurity has been well studied in developed countries, data from developing countries, such as Jordan, are still limited. This retrospective study analysed medical records to determine possible risk factors leading to preterm birth in the Irbid governorate of Jordan. All preterm births during the year 2011 were reviewed. Abstracted data included mother's age and gravidity. Newborn information included gender, birthweight and gestational age at birth. A total of 647 singleton births were included. There were more females than males (54.9% vs. 45.1%), with 75.6% being the second child or more. Half the mothers (50.2%) were 25-35 years of age. Factors associated with preterm birth were male gender (P = 0.008), maternal age > 35 years (P = 0.005) and first birth (P = 0.003). Nurses need to provide support and education to mothers with potential risk about reproductive health and family planning.

This study aimed to analyze the prevalence and the risk factors associated with lifetime sexual violence among people with disabilities (PWDs) in Burkina Faso. We conducted a secondary analysis of a cross-sectional study carried out in four regions (Central, Central-East, Central-West and 'Hauts Bassins' regions) of Burkina Faso. PWDs were selected during a household survey through a two-stage random sampling technique. The prevalence of sexual violence in people disabilities was 7.4% (95%: CI 5.8-9.4). Females with disabilities were more likely than males with disabilities to report lifetime sexual violence (8.9% vs 4.9%). The place where the person usually spends time and the disability duration were significantly associated with the occurrence of sexual violence among female with disability. No significant association was found between different and sexual violence among people with disabilities. Sexual violence is frequent among PWDs in Burkina Faso. Specific policy to protect PWDs particularly women with disabilities from sexual violence is urgently needed.

This study aimed to characterize Helicobacter pylori virulence genes and the associated behavioral factors among dyspeptic patients in Burkina Faso. Two hundred and fifty (250) stool samples were collected from patients with dyspepsia seen at health centers in Ouagadougou, Burkina Faso. Bacterial deoxyribonucleic acid (DNA) was extracted using a commercial kit. Virulence genes were detected using conventional multiplex Polymerase Chain Reaction with specific primers. The overall prevalence of Helicobacter pylori of the 250 participants was 91.20%. Ca-gA virulence gene was present among 20.19% of individuals, while babA2 and vacA were detected respectively among 9.65% and 67.54% of the population positive for Helicobacter pylori. Among vacA subtypes, vacAs1 was the most frequent, with 39.04%, followed by vacAi1 (19.74%), vacAi2 (17.54%), and vacAs2 with 10.96%. Regarding vacAm1 and vacAm2, they were less frequent at 6.14% each. "Handwashing three times or less per day" significantly increased the risk of having vacAi2 allele and H. pylori rRNA16s, with p-values of 0.013 and 0.020, respectively. The consumption of non-tap water increases the risk of carrying the cagA virulence gene. Additionally, H. pylori-positive

Materials and Methods: We analyzed SARS-CoV-2 RT-PCR routine diagnostic data in Burkina Faso. Data were collected from March 9, 2020 to September 30, 2020 in the framework of the COVID-19 surveillance. Sensitivity, specificity, predictive values, and Kappa concordance were used to check the correlation between COVID-19 symptoms and the RT-PCR results. Results: A total of 2217 participants were tested for COVID-19 using RT-PCR, of them 779 COVID-19 positive. The mean age of the participants was 38.7± 17.69 years. Suspected symptoms presented by participants were fever (40.4%), cough (38.6%), asthenia (27.3%), headache (23.6%), dyspnea (20.8%), and odynophagia (16.3%). The sensitivity of presence of at least a clinical sign compared to RT-PCR results was 62.13% and the specificity was 39.85%. The kappa agreement between the presence of COVID-19 suspected symptoms and RT-PCR results was 0.017. The presence of aguesia and/or anosmia in patients induced a positive predictive value of RT-PCR of 91.30%. Conclusion: The correlation between the COVID-19 symptoms and RT-PCR results in the diagnosis of COVID-19 was very weak. The present study confirms that most clinical signs associated with SARS-CoV-2 infection are not specific to COVID-19, hence the need to always combine RT-PCR or other biological tests with the clinical diagnosis. However, aguesia and anosmia are of interest with a high degree of RT-PCR positivity when present in a COVID-19 suspected patient.

Materials and methods Ten (10) SARS-CoV-2 serological rapid diagnostic tests (RDTs) for SARS-CoV-2 IgG/IgM were evaluated with two (2) groups of plasma tested positive for one and negative for the other with the WANTAI SARS-CoV-2 Ab ELISA. The diagnostic performance of the SARS-CoV-2 serological RDTs and their agreement with the reference test were calculated with their 95% confidence intervals. Results The sensitivity of serological RDTs ranged from 27.39 to 61.67% and the specificity from 93.33 to 100% compared to WANTAI SARS-CoV-2 Ab ELISA test. Of all the tests, two tests (STANDARD Q COVID-19 IgM/IgG Combo SD BIOSENSOR and COVID-19 IgG/IgM Rapid Test (Zhejiang Orient Gene Biotech Co., Ltd)) had a sensitivity greater than 50%. In addition, all ten tests had specificity greater tha...

The Panbio TM COVID-19 Ag test was evaluated from January 26 to March 31, 2021 in symptomatic and asymptomatic patients in the medical Centre of Kossodo. A total of 268 individuals were tested by both SARS-CoV-2 RT-PCR, and antigen RDT. Of these 268 individuals, 52 were positive and 216 were negative for COVID-19 RT-PCR. The performance parameters of the test and its Kappa agreement with the RT-PCR were calculated according to the presence or absence of symptoms in the patients on one hand, and according to the time onset of symptoms on the other hand. The sensitivity of the Panbio™ COVID-19 Ag Rapid Test ranged from 29.63% (95% CI: 13.75 to 50.18) among COVID-19 asymptomatic patients, to 87.5% (95% CI: 52.91 to97.76) among symptomatic patients with symptom onset time of 1-5 days. Similarly, the Panbio™ COVID-19 Ag Rapid Test specificity was 97.3% (95% CI: 90.58 to 99.67) and 96.4% (95% CI: 91.81 to 98.82) in symptomatic and asymptomatic RT PCR negative patients. The Panbio™ COVID-19 Ag Rapid Test shows good performance in detecting COVID-19 cases in patients with a symptom onset time of less than seven (7) days. This performance is even better when the symptom onset is reduced to five (5) days. The results show that the antigen RDT is not suitable for COVID-19 detection among asymptomatic patients.

This study aimed to screen specific mutations and variants of SARS-CoV-2 circulating in Burkina Faso. Methods: This study included symptomatic and asymptomatic individuals who underwent diagnostic testing for SARS-CoV-2 by RT-PCR on nasopharyngeal and oropharyngeal swabs from 7 December 2021 to 12 January 2022. Samples from individuals with a Ct value ≤ 33 were selected for the variants-specific mutation screening. The screening was performed using two kits, "SNPsig ® SARS-COV-2 (Escape PLEX)" and "SNPsig® VariPLEX™ (COVID-19) Real-Time PCR Assay". Results: SARS-CoV-2 prevalence was 18.9% (332/1758). A total of 113 samples (34.04%) had a Ct value less than (≤ 33), with only 20.35% (23/113) belonging to symptomatic patients. The mean age was 39.01±13 years. The Beta variant (B.1.351) was the most detected one comprising 78.8% (89/113) of variants. Gamma and Delta variants were detected at a low proportion of 0.9% (1/113). No mutation or variant was detected in seven (6.2%) samples. Conclusion: Specific mutation screening detected Beta (B.1.351), Gamma (P.1), and Delta (B.1.617.2) variants of SARS-CoV-2 circulating in Burkina Faso. The absence of mutations in some samples might suggest variants other than those detected.

In fact, the country has known a peak of the second wave, which began in November, and ended around January 2021. Biological diagnosis has played a key role in the management of COVID-19. The aim of this review paper is to address the practical aspects that laboratories have faced in order to meet the challenge of SARS-CoV-2 diagnosis in Burkina Faso. According to international requirements, Burkina Faso has used real-time Reverse Transcription Polymerase Chain Reaction (rRT-PCR) as the “gold standard” for the diagnosis of COVID-19. From March 9, 2020 to July 31, 2021, in Burkina Faso, laboratories involved in COVID-19 diagnosis analyzed 226,189 samples by molecular tests and 2, 352 samples by rapid antigenic tests, whose peak was in January 2021 with 35,984 samples analyzed. The daily average rate of samples analysis was 456.02 tests. The majority of the individuals requesting COVID-19 tests were travelers (62.00%), follow...

This vulnerability is supported by risky sexual behaviours, which need to be well described. The objective of this study is to identify predictors of sexual behaviours at risk of HIV infection among PWD in Burkina Faso. We conducted a population-based cross-sectional study on disability and HIV in four regions in Burkina Faso. PWD were selected through a probabilistic method. The Washington Group Short questionnaire was used to identify PWD. Five sexual risk behaviours were considered in this analysis (having multiple sex partners, starting sex at an early age, having had sex with a nonregular partner, sex in return for payment and condomless sex). A composite variable was created and called "risky sexual behaviour (RSB)", which was defined in three categories (low risk, moderate risk and high risk) based on the co-occurrence of the individual sexual risk behaviours. Generalized structural equation was used to identify the predictors of RSB withincome possession as a mediator. A total of 973 PWD were included in this study. The proportion of PWD who were engaged in at least two risky sexual behaviours was 9.5% (95%CI: 6.5-13.8), those with one risky sexual behaviour represented 42.8% (95%CI: 39.4-46.3) and less than half ( 47.7% (95%CI: 43.3-52.1)) werenot engaged in risky sexual behaviour. The prevalence of HIV increased with the level of risky sexual behaviour. Age, education level and type of disability have a significant direct effect on RSB. Indeed, the oddof engaging in sexual risk behaviour was low among PWD who attended at least secondary school compared to those who were not schooled (adjusted odds ratio (aOR): 0.62 (95%CI: 0.41-0.92). The indirect effect of sex on RSB mediating by income possession was significant. Indeed, women with income have a low oddof engaging in RSB compared to men (aOR: 0.83 [95%CI: 0.71-0.98]). Our results confirm a certain ambivalence in the sexuality of people with disabilities. Hence, there is a need for a particular focus on risky sexual behaviour to enable the development of an effective HIV strategy in this group.

The Washington Group Short questionnaire was used to identify people with disabilities during a household survey. Blood samples for HIV testing were collected using the Dried Blood Sampling (DBS) method. HIV testing was performed according to the Niger national HIV testing guideline. A total of 21,979 persons aged 15-69 years were screened, of them 2237 (10.17%) had disabilities and 949 participants (4.32%) had severe disabilities (level 3 or 4). Finally, 821 participants agreed to participate in the HIV testing. Female persons with disabilities accounted for the majority (52.25%). People with physical impairment were mostly represented (39.27%) followed by those with visual impairment (38.66%). At least one-third had multiple impairs (36.91%). HIV prevalence among person with disabilities was 0.66% (95% CI: 0.33-1.30). There is no difference between HIV prevalence and type of disabilities or socio-demographic characteristics. Hence, there is a need to consider them in the development and implementation of an effective HIV strategy.
