Prevalence of SARS-CoV-2 among high-risk populations in Lome (Togo) in 2020.

ABSTRACT: BACKGROUND:In December 2019, the COVID-19 outbreak began in China and quickly spread throughout the world and was reclassified as a pandemic in March 2020. The first case of COVID-19 was declared in Togo on March 5. Two months later, few data were available to describe the circulation of the new coronavirus in the country. OBJECTIVE:This survey aimed to estimate the prevalence of SARS-CoV-2 in high-risk populations in Lomé. MATERIALS AND METHODS:From April 23, 2020, to May 8, 2020, we recruited a sample of participants from five sectors: health care, air transport, police, road transport and informal. We collected oropharyngeal swabs for direct detection through real-time reverse transcription polymerase chain reaction (rRT-PCR) and blood for antibody detection by serological tests. The overall prevalence (current and past) of infection was defined by positivity for both tests. RESULTS:A total of 955 participants with a median age of 36 (IQR 32-43) were included, and 71.6% (n = 684) were men. Approximately 22.1% (n = 212) were from the air transport sector, 20.5% (n = 196) were from the police sector, and 38.7% (n = 370) were from the health sector. Seven participants (0.7%, 95% CI: 0.3-1.6%) had a positive rRT-PCR test result at the time of recruitment, and nine (0.9%, 95% CI: 0.4-1.8%) were seropositive for IgM or IgG against SARS-CoV-2. We found an overall prevalence of 1.6% (n = 15), 95% CI: 0.9-2.6%. CONCLUSION:The prevalence of SARS-CoV-2 infection among high-risk populations in Lomé was relatively low and could be explained by the various measures taken by the Togolese government. Therefore, we recommend targeted screening.

Project description:OBJECTIVES:Mental health is a largely neglected issue among in Sub-Saharan Africa, especially among key populations at risk for HIV. The aim of this study was to estimate the prevalence of psychological distress (PD) and to assess the factors associated among males who have sex with males (MSM), female sex workers (FSW) and drug users (DU) in Togo in 2017. STUDY DESIGN:A cross-sectional bio-behavioral study was conducted in August and September 2017 using a respondent-driven sampling (RDS) method, in eight cities in Togo. METHODS:A standardized questionnaire was used to record sociodemographic characteristics and sexual behaviors. The Alcohol Use Disorders Identification Test (AUDIT) and a subset of questions from the Tobacco Questions for Survey were used to assess alcohol and tobacco consumption respectively. PD was assessed with the Kessler Psychological Distress Scale. A blood sample was taken to test for HIV. Descriptive statistics, univariable and multivariable ordinal regression models were used for analysis. RESULTS:A total of 2044 key populations including 449 DU, 952 FSW and 643 MSM with a median age of 25 years, interquartile range (IQR) [21-32] were recruited. The overall prevalence of mild PD among the three populations was 19.9% (95%CI = [18.3-21.8]) and was 19.2% (95%CI = [17.5-20.9]) for severe/moderate PD. HIV prevalence was 13.7% (95%CI = [12.2-15.2]). High age (? 25 years) [aOR = 1.24 (95% CI: 1.02-1.50)], being HIV positive [aOR = 1.80 (95% CI: 1.31-2.48)] and hazardous alcohol consumption [aOR = 1.52 (95% CI: 1.22-1.87)] were risk factors for PD. Secondary [aOR = 0.52 (95% CI: 0.42-0.64)] or higher [aOR = 0.46 (95% CI: 0.32-0.64)] education levels were protective factors associated with PD. FSW [OR = 0.55 (95% CI: 0.43-0.68)] and MSM [OR = 0.33 (95% CI: 0.24-0.44)] were less likely to report PD compared with DU. CONCLUSION AND RECOMMENDATIONS:This is the first study conducted among a large, nationally representative sample of key populations in Togo. The prevalence of PD is high among these populations in Togo and was associated to HIV infection. The present study indicates that mental health care must be integrated within health programs in Togo with a special focus to key populations through interventions such as social support groups.
