Background To date, there is no effective treatment for COVID-19, which is a pandemic disease, caused by a novel coronavirus called SARS-CoV-2. In Togo, where four in five people practice self-medication, the absence of a cure for COVID-19 and the constant progression of the disease requires an assessment of self-medication patterns in the context of the pandemic. This study aimed to estimate the prevalence of self-medication to prevent COVID-19 and its associated factors in Lomé, Togo. Methods A cross-sectional study was conducted in Lomé, the capital city of Togo, from April 23rd to May 8th, 2020, with a sample of participants from five sectors: the healthcare, air transport, police, road transport and informal sectors. The participants were invited to provide information about their self-medication practices to prevent COVID-19 in the 2 weeks preceding the survey. Results A total of 955 participants (71.6% men) with a median age of 36 (IQR 32–43) were included. Approximately 22.1% were in the air transport sector, 20.5% were in the police sector, and 38.7% were in the health sector. The overall prevalence of self-medication to prevent COVID-19 was 34.2% (95% CI: 31.2–37.3%). The most commonly used products were vitamin C (27.6%) and traditional medicine (10.2%). Only 2.0% of participants reported using chloroquine/hydroxychloroquine. Female sex (aOR=1.90; p< 0.001), work in the health sector (aOR=1.89; p= 0.001), secondary education level (aOR= 2.28; p= 0.043) and university education level (aOR= 5.11; p< 0.001) were associated with self-medication. Conclusion One-third of the individuals in high-risk populations in Lomé practiced self-medication. Intensifying awareness campaigns is crucial to fight misinformation about alleged COVID-19 prevention products on social media.
IntroductionAntiretroviral treatment (ART) has been scaled up over the last decade but compared to adults, children living with HIV are less likely to receive ART. Moreover, children and adolescents are more vulnerable than adults to virological failure (VF) and emergence of drug resistance. In this study we determined virological outcome in perinatally HIV-1-infected children and adolescents receiving ART in Togo.MethodsHIV viral load (VL) testing was consecutively proposed to all children and adolescents who were on ART for at least 12 months when attending HIV healthcare services for their routine follow-up visit (June to September 2014). Plasma HIV-1 VL was measured using the m2000 RealTime HIV-1 assay (Abbott Molecular, Des Plaines, IL, USA). Genotypic drug resistance was done for all samples with VL>1000 copies/ml.Results and discussionAmong 283 perinatally HIV-1-infected children and adolescents included, 167 (59%) were adolescents and 116 (41%) were children. The median duration on ART was 48 months (interquartile range: 28 to 68 months). For 228 (80.6%), the current ART combination consisted of two nucleoside reverse transcriptase inhibitors (NRTIs) (zidovudine and lamivudine) and one non-nucleoside reverse transcriptase inhibitor (NNRTI) (nevirapine or efavirenz). Only 28 (9.9%) were on a protease inhibitor (PI)-based regimen. VL was below the detection limit (i.e. 40 copies/ml) for 102 (36%), between 40 and 1000 copies/ml for 35 (12.4%) and above 1000 copies/ml for 146 (51.6%). Genotypic drug-resistance testing was successful for 125/146 (85.6%); 110/125 (88.0%) were resistant to both NRTIs and NNRTIs, 1/125 (0.8%) to NRTIs only, 4/125 (3.2%) to NNRTIs only and three harboured viruses resistant to reverse transcriptase and PIs. Overall, 86% (108/125) of children and adolescents experiencing VF and successfully genotyped, corresponding thus to at least 38% of the study population, had either no effective ART or had only a single effective drug in their current ART regimen.ConclusionsOur study provided important information on virological outcome on lifelong ART in perinatally HIV-1-infected children and adolescents who were still on ART and continued to attend antiretroviral (ARV) clinics for follow-up visits. Actual conditions for scaling up and monitoring lifelong ART in children in resource-limited countries can have dramatic long-term outcomes and illustrate that paediatric ART receives inadequate attention.
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.
Investment in SARS-CoV-2 sequencing in Africa over the past year has led to a major increase in the number of sequences generated, now exceeding 100,000 genomes, used to track the pandemic on the continent. Our results show an increase in the number of African countries able to sequence domestically, and highlight that local sequencing enables faster turnaround time and more regular routine surveillance. Despite limitations of low testing proportions, findings from this genomic surveillance study underscore the heterogeneous nature of the pandemic and shed light on the distinct dispersal dynamics of Variants of Concern, particularly Alpha, Beta, Delta, and Omicron, on the continent. Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve, while the continent faces many emerging and re-emerging infectious disease threats. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century.

Results: A total of 955 participants (71.6% of men) with a median age of 36 (IQR 32–43) were included. Around 22.1% were in the air transport sector, 20.5% in police, and 38.7% in the health sector. The overall prevalence of self-medication to prevent Covid-19 was 34.2% (95CI%: 31.2-37.3%). Most commonly used products were vitamin C (27.6%) and traditional medicine (10.2%). Only 2.0% of participants reported using Chloroquine/Hydroxychloroquine. Female sex (aOR=1.90; p<0.001), working in the health sector (aOR=1.89; p= 0.001), secondary education level (aOR= 2.28; p= 0.043) and university education level (aOR= 5.11; p<0.001) were associated with self-medication. Conclusion: One third of high-risk populations in Lomé have practiced self-medication. Intensifying awareness campaigns is crucial to fight misinformation about alleged Covid-19 prevention products on social media.
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. Anal swabs were collected to test HPV, herpes simplex virus (HSV), and 7 STIs. Results Among the 207 MSM, HIV and high-risk HPV (hrHPV) overall prevalence were 26.1% and 44.9%, respectively. The most common hrHPV types were HPV-35 (15.0%) and HPV-16 (13.0%). Prevalence of hrHPV and multiple HPV infections were higher among HIV-infected than among HIV-uninfected MSM (85.2% vs 30.7%, P < 10–5 and 85.2% vs 28.7%, P < 10–5, respectively). Other STIs, except hepatitis B virus, were also more prevalent among HIV-infected MSM (Neisseria gonorrhoeae, P = .03; Mycoplasma genitalium, P = .04; HSV-2, P = .001; and a trend for Chlamydia trachomatis, P = .06). In multivariate analysis (adjusted odds ratio [95% confidence interval]), HIV (10.1 [4.0–25.6]), living in Lomé (2.8 [1.1–7.1]), HSV-2 excretion (26.7 [2.9–244.3]), C. trachomatis (11.7 [2.3–58.9]), and M. genitalium infection (9.6 [3.1–29.9]) were associated with increased risk of hrHPV infection. Conclusions We report a high burden of anal STIs with an unusual hrHPV type distribution among MSM, highlighting the critical need of implementation of a national strategy regarding prevention of STIs and vaccination against HPV.
Background The coronavirus disease 2019 (COVID-19) vaccines can cause adverse events that can lead to vaccine hesitancy. This study aims at estimating the prevalence of severe adverse events (SAEs) and their associated factors among health professionals vaccinated with ChAdOx1 nCoV-19 vaccine in Togo. Methods A cross-sectional study was conducted from March 13th to 19th, 2021 in Togo among health professionals who received the first dose of the vaccine. An online self-administered questionnaire was used to collect sociodemographic and vaccination data. SAEs were defined as one resulting in hospitalization, medical consultation, or inability to work the day following the administration of the vaccine. Data analysis were performed using R© 4.0.1 software, and a 5% significance level was considered. Results A total of 1,639 health professionals (70.2% male) with a median age of 32 (interquartile range: 27-40) were enrolled. At least one adverse event was reported among 71.6% of participants (95% CI = [69.3-73.8]). The most commonly reported adverse events were injection site pain (91.0%), asthenia (74.3%), headache (68.7%), soreness (55.0%), and fever (47.5%). An increased libido was also reported in 3.0% of participants. Of the participants who experienced adverse events, 18.2% were unable to go to work the day after vaccination, 10.5% consulted a medical doctor, and 1.0% were hospitalized. The SAEs’ prevalence was 23.8% (95% CI = [21.8-25.9]). Being <30 years (AOR = 5.54; p<0.001), or 30-49 years (AOR = 3.62; p<0.001) and being female (AOR = 1.97; p<0.001) were associated with SAEs. Conclusions High prevalence of SAEs have been observed in health professionals in Togo after ChAdOx1 nCoV-19 vaccination especially in young people and females. However, these data are reassuring as they inform on COVID-19 vaccines’ SAE management. Systematic prescription of antalgics or antipyretics could be proposed to young people who get vaccinated.
BackgroundWith widespread use of antiretroviral (ARV) drugs in Africa, one of the major potential challenges is the risk of emergence of ARV drug-resistant HIV strains. Our objective is to evaluate the virological failure and genotypic drug-resistance mutations in patients receiving first-line highly active antiretroviral therapy (HAART) in routine clinics that use the World Health Organization public health approach to monitor antiretroviral treatment (ART) in Togo.MethodsPatients on HAART for one year (10-14 months) were enrolled between April and October 2008 at three sites in Lomé, the capital city of Togo. Plasma viral load was measured with the NucliSENS EasyQ HIV-1 assay (Biomérieux, Lyon, France) and/or a Generic viral load assay (Biocentric, Bandol, France). Genotypic drug-resistance testing was performed with an inhouse assay on plasma samples from patients with viral loads of more than 1000 copies/ml. CD4 cell counts and demographic data were also obtained from medical records.ResultsA total of 188 patients receiving first-line antiretroviral treatment were enrolled, and 58 (30.8%) of them experienced virologic failure. Drug-resistance mutations were present in 46 patients, corresponding to 24.5% of all patients enrolled in the study. All 46 patients were resistant to non-nucleoside reverse-transcriptase inhibitors (NNRTIs): of these, 12 were resistant only to NNRTIs, 25 to NNRTIs and lamivudine/emtricitabine, and eight to all three drugs of their ARV regimes. Importantly, eight patients were already predicted to be resistant to etravirine, the new NNRTI, and three patients harboured the K65R mutation, inducing major resistance to tenofovir.ConclusionsIn Togo, efforts to provide access to ARV therapy for infected persons have increased since 2003, and scaling up of ART started in 2007. The high number of resistant strains observed in Togo shows clearly that the emergence of HIV drug resistance is of increasing concern in countries where ART is now widely used, and can compromise the long-term success of first- and second-line ART.
