HIV self-testing: A highly acceptable and feasible strategy for reconnecting street adolescents with HIV screening and prevention services in Togo (The STADOS study).
PLoS One
October 2024
Introduction: HIV self-testing is a complementary screening strategy that could facilitate access to HIV care services for street adolescents. The objectives of this study were to assess the acceptability and feasibility of HIV self-testing and their associated factors, to estimate HIV prevalence among street adolescents in Togo, and to describe the sexual behavior of this population.
Methods: A cross-sectional study was conducted between July 2021 and May 2022 in Lomé and Kara (Togolese cities with the highest number of street adolescents).
Article Synopsis
- * A study involving 30 Togolese female sex workers analyzed 156 HPV genome sequences from cervical and anal swabs, revealing identical infections but varying genetic diversity across HPV types and sites.
- * Low-risk HPVs showed more mutations induced by APOBEC3 in the E4 and E6 genes compared to high-risk HPVs, which had fewer mutations, suggesting different cancer risk potentials among HPV types.
Background: In Togo, few data are available on viral hepatitis in street adolescents, a vulnerable population due to their lifestyle. The aim of this study was to describe the lifestyle of street adolescents (sexual practices and drug use), to estimate the prevalence of hepatitis B and C viruses, and to describe their HBV immunization profile in Togo.
Methods: A cross-sectional study was conducted in Lomé (Togo) in July 2021.
Background: There is almost no data on the circulation of SARS-CoV-2 among street adolescents. We conducted a study to document the immunization status of street adolescents in Togo against different variants of SARS-CoV-2.
Methods: A cross-sectional study was carried out in 2021 in Lomé, the city with the highest number of COVID 19 cases in Togo (60%).
Background: The extent of SARS-CoV-2 circulation in African countries is still unclear. Seroprevalence studies are a common approach to epidemiological surveillance, allowing estimation of the proportion of people who have had contact with the virus. We aimed at estimating the seroprevalence of anti-SARS-CoV-2 antibodies and associated factors in Togo at the national level in 2021 according to age groups, gender, and place of residence (rural or urban).

- The study aimed to determine how common malaria and Covid-19 are among febrile patients in Lomé, using various testing methods over two months in 2020.
- A total of 243 patients were tested, revealing a malaria prevalence of about 25%, while the presence of SARS-CoV-2 was found in approximately 7.4% of the participants.
- The findings suggest that there may be cross-reactivity between Covid-19 and malaria in rapid tests, indicating the need for PCR testing to accurately diagnose Covid-19 in areas where malaria is common.
Article Synopsis
- A study conducted in Togo in 2017 aimed to determine the prevalence and risk factors for Trichomonas vaginalis (T. vaginalis) among female sex workers (FSW) using respondent-driven sampling and molecular tests.
- The results showed a T. vaginalis prevalence of 6.5%, with additional findings of other sexually transmitted infections (STIs) in the population, including HIV.
- Key factors associated with T. vaginalis infection included living in Lomé, having sexual intercourse before age 18, and being infected with Chlamydia trachomatis, highlighting the need for further research to understand its epidemiology in Togo.*
Objectives: This study aimed to describe HIV testing uptake, as well as HIV prevalence and its associated factors among older adults aged ≥50 years in health facilities in Togo.
Methods: A cross-sectional study was carried out from February 2018 to June 2019 among hospitalized older adults aged ≥50 years in tertiary and secondary hospitals in Togo. HIV testing was performed according to the national algorithm.
Article Synopsis
- COVID-19 began in December 2019 in China and was declared a pandemic by March 2020, with Togo reporting its first case on March 5, 2020.
- A survey conducted from April 23 to May 8, 2020, aimed to estimate the prevalence of SARS-CoV-2 among high-risk groups in Lomé, using oropharyngeal swabs and blood samples for testing.
- Results showed a low overall prevalence of 1.6% among 955 participants, with government measures likely contributing to the low rates of infection, leading to a recommendation for targeted screening in these high-risk populations.
Prevalence of Human Papillomavirus, Human Immunodeficiency Virus, and Other Sexually Transmitted Infections Among Men Who Have Sex With Men in Togo: A National Cross-sectional Survey.
Clin Infect Dis
August 2019
Background: Sub-Saharan Africa is a region of both high human immunodeficiency virus (HIV) and anal cancer incidence. We conducted the first national study in Togo to assess human papillomavirus (HPV), HIV, and other sexually transmitted infection (STI) prevalence among men who have sex with men (MSM).
Methods: A multicentric cross-sectional study was conducted among MSM recruited in 4 Togolese cities.
Background: No data are available on HIV/hepatitis B virus (HBV) or hepatitis C virus coinfection in Togo, and patients are not routinely tested for HBV infection.
Objective: To determine the prevalence of HBV and the risk of HBV drug resistance during antiretroviral treatment in HIV-coinfected patients in Togo.
Method: This cross-sectional study was carried out in Lomé, Togo, from January 2010 to December 2011 among HIV-infected patients who had been on antiretroviral therapy (ART) for at least 6 months.
Context: In the context of implementing a serological and behavioural surveillance system among drugs users, this study estimated the prevalence of HIV infection and related risk behaviours among drug users (DUs) in Togo.
Method: A cross-sectional study was conducted among DUs in Togo from November 2011 to January 2012. This study involved all DUs regardless of the type of drug and the mode of consumption, over the age of 18 years, who had lived in Togo for at least 3 months.
