RESUMEN
ABSTRACTOur study aims to determine the predictors of access to HIV services among disabled persons in two West African countries. This was a secondary analysis from a cross-sectional study carried out in Burkina Faso, in 2017 and Niger, in 2018. People with a disability of severity 3 or 4 and aged 15-69 were included in the study. Access to HIV-related services was measured separately through three variables (access to condoms when needed, history of testing for HIV and ever attended at an HIV-related service). Factors associated with access to HIV-related services were identified using logistic regression. 1794 participants were recorded, including 973 in Burkina Faso and 821 in Niger. The ability to easily obtain a condom when needed was reported by 29.4% of respondents in Burkina Faso and 5.7% of respondents in Niger. The proportion of participants who had been tested for HIV was 32.2% in Burkina Faso and 13.6%. We observed that 5.7% and 3.5% of the participants were in contact with an HIV-related service. Only educational status was associated with access to HIV prevention services in both countries. There is a need to increase the access to HIV prevention for disabled persons in the two countries.

BACKGROUND: Many men who have sex with men (MSM) are at significant risk for HIV infection. The objective of this study was to determine the prevalence and correlates of HIV infection among MSM in Burkina Faso. METHODS: A cross-sectional biological and behavioral survey was conducted from January to August 2013 among MSM in Ouagadougou and Bobo-Dioulasso. MSM 18 years old and above were recruited using respondent driven sampling (RDS). A survey was administered to study participants followed by HIV testing. Population prevalence estimates and 95% confidence intervals (CI) adjusted for the RDS design were produced using the RDS Analysis Tool version 6.0.1 (RDS, Inc., Ithaca, NY). RESULTS: A total of 662 MSM were enrolled in Ouagadougou (n = 333) and Bobo-Dioulasso (n = 329). The majority were unmarried, with an average age of 22.1 ± 4.4 years old in Ouagadougou and 23.1 ± 4.7 years old in Bobo-Dioulasso. RDS-adjusted HIV prevalence was 1.7% (95% CI: 0.9-3.1) in Ouagadougou and 2.7% (95% CI: 1.6-4.6) in Bobo-Dioulasso. HIV prevalence among MSM under 25 years old was 1.3% (95% CI: 0.6-2.8) and 0.9% (95% CI: 0.4-2.5) respectively in Ouagadougou and Bobo-Dioulasso, compared to 5.4% (95% CI: 2.2-12.5) and 6.6% (95% CI: 3.4-12.3) among those 25 years old or older in these cities (p = 0.010 and p < 0.001). CONCLUSIONS: Results from this first biological and behavioral survey among MSM in Burkina Faso suggest a need for programs to raise awareness among MSM and promote safer sex, particularly for young MSM to prevent HIV transmission. These programs would need support from donors for innovative actions such as promoting and providing pre-exposure prophylaxis, condoms and water-based lubricants, HIV counseling, testing, early treatment initiation and effective involvement of the MSM communities.

BACKGROUND: Dengue fever (DF) is endemic in Burkina Faso, with 70% of its burden supported by the Central Health Region. Then, a single confirmed case can no longer mean an epidemic. This study aimed at describing trends and setting epidemic thresholds of DF in the Central Health Region. DATA AND METHODS: An ecological study was conducted using monthly data from DF surveillance between 2016 and 2021. Three methods were applied to set alert and intervention thresholds of DF monthly incidence rate: mean [mean + 2 SD], median [3rd quartile] and cumulative sum (C-sum) [C-sum + 1.96 SD]. These thresholds were plotted with the monthly incidence rates for 2021. RESULTS: In total, 54,429 cases were reported between 2016 and 2021. Dengue cases increased biannually. The median annual incidence rate did not vary significantly across years [Kruskal-Wallis: χ2(5) = 9.825; p = 0.0803]. Within a year, the monthly incidence rate fell under 48.91 cases per 100,000 inhabitants between January and September and peaked in October or November. With the mean and C-sum methods, the 2021 monthly incidence rate remained below the intervention thresholds (Mean + 2 SD and C-sum + 1.96 SD). With the median method, the incidence rate exceeded the alert and intervention thresholds in July-September 2021. CONCLUSIONS: If the DF incidence varied within a year due to the seasons, it was relatively stable between 2016 and 2021. The mean and C-sum methods based on the mean were subject to extreme values, giving high thresholds. The median method seemed better for capturing the abnormal increase in dengue incidence.

BACKGROUND: Syphilis among female sex workers (FSW) remains a public health concern due to its potential impact on their health and the possibility of transmission to their clients, partners, and children. Recent data on the prevalence of syphilis in the population in West Africa are scarce. The objective of this study was to measure the seroprevalence of syphilis serological markers among female sex workers in Burkina Faso. METHODS: We conducted a cross-sectional survey among FSW between February 2013 and May 2014. Participants were recruited using respondent-driven sampling (RDS) methods in five cities of Burkina Faso (Ouagadougou, Bobo-Dioulasso, Koudougou, Ouahigouya, and Tenkodogo). FSW were enrolled and screened for syphilis using a syphilis serological rapid diagnostic test. Data from all cities were analyzed with Stata version 14.0. RESULTS: A total of 1045 FSW were screened for syphilis. Participants' mean age was 27.2 ± 0.2 years. The syphilis serological markers were detected in 5.6% (95% CI: 4.4-7.2) of the participants whereas active syphilis was seen in 1.4% (95% CI: 0.9-2.4). RDS weighted prevalence of syphilis serological markers and active syphilis by city were, respectively, estimated to be 0.0% to 11.0% (95% CI: 8.1-14.7) and 0.0% to 2.2% (95% CI: 1.1-4.4). No syphilis markers were found among Ouahigouya FSW. Low education level and high number of clients were factors associated with syphilis markers among the FSW. CONCLUSION: The prevalence of syphilis markers was high during this study among FSW. This highlights the need to reinforce the comprehensive preventive measures and treatment of syphilis in this population.
RESUMEN
BACKGROUND: 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.
