Progress from morbidity control to elimination as a public health problem of schistosomiasis and the status of soil-transmitted helminth infection in Togo: a second impact assessment after ten rounds of mass drug administration.

BACKGROUND: Due to the burden of schistosomiasis (SCH) and soil-transmitted helminths (STH), Togo Ministry of Health launched a program for Preventive Chemotherapy Neglected Tropical Diseases (PC-NTDs) in 2009, initiating integrated mass drug administration (MDA) the following year for the three PC-NTDs: SCH, STH and onchocerciasis. Significant reduction of infection across the country was noted in 2015 during the first impact assessment, following 5 years of high-coverage MDA implemented at the sub-district level for SCH and district level for STH. After another 5 years of effective MDA, a second survey was conducted in 2021 to re-evaluate the situation of SCH and STH. METHODS: A cross-section of school-aged children was taken across ten districts of Togo. A total of 302 schools in 92 sub-districts were sampled, with 24 school-aged children per school resulting in 7248 children surveyed. Urine samples were tested by haemastix® for Schistosoma haematobium, with urine filtration for the presence of eggs conducted on haematuria-positive samples. Stool samples were collected in a subset of 34 sub-districts in seven out of the ten surveyed districts, where STH and Schistosoma mansoni endemicity was high during the 2015 impact assessment. Duplicate (two) Kato-Katz analysis was performed for each stool sample. Sociodemographic and school-level water, sanitation and hygiene information was also collected. RESULTS: Overall, SCH prevalence was 5.90% (95% CI: 5.4-6.5), with 5.09% (95% CI: 4.64-5.67) for S. haematobium and 2.56% (95% CI: 1.98-3.29) for S. mansoni. STH prevalence was 19.7% (95% CI: 18.2-21.4), with 19.6% (95% CI: 18.1-21.3) hookworm, 0.08% (95% CI: 2.2-5.8) Trichuris trichiura and 0.04% (95% CI: 0.01-0.33) Ascaris lumbricoides. Compared to baseline, a significant reduction in both SCH (22.2% to 5.90%) and STH (29.2% t0 19.7%) prevalence was observed. Children aged 5-9 years were less infected than older peers aged 10-14 years: 4.76% vs. 7.53% (P < 0.01) for SCH and 17.2% vs. 23.0% (P < 0.01) for STH. CONCLUSIONS: After 10 years of high coverage integrated MDA, Togo has achieved low prevalence SCH infection through the sub-district MDA implementation with considerable infection heterogeneity within sub-districts. As STH infection has not reached a level where the infections are not a public health problem, the sub-district treatment strategy could also be adopted in addition to improvement of treatment coverage among preschool age children and hygiene and sanitation practices.

Restarting Neglected Tropical Diseases Programs in West Africa during the COVID-19 Pandemic: Lessons Learned and Best Practices.

Countries across West Africa began reporting COVID-19 cases in February 2020. By March, the pandemic began disrupting activities to control and eliminate neglected tropical diseases (NTDs) as health ministries ramped up COVID-19-related policies and prevention measures. This was followed by interim guidance from the WHO in April 2020 to temporarily pause mass drug administration (MDA) and community-based surveys for NTDs. While the pandemic was quickly evolving worldwide, in most of West Africa, governments and health ministries took quick action to implement mitigation measures to slow the spread. The U.S. Agency for International Development's (USAID) Act to End NTDs | West program (Act | West) began liaising with national NTD programs in April 2020 to pave a path toward the eventual resumption of activities. This process consisted of first collecting and analyzing COVID-19 epidemiological data, policies, and standard operating procedures across the program's 11 countries. The program then developed an NTD activity restart matrix that compiled essential considerations to restart activities. By December 2020, all 11 countries in Act | West safely restarted MDA and certain surveys to monitor NTD prevalence or intervention impact. Preliminary results show satisfactory MDA program coverage, meaning that enough people are taking the medicine to keep countries on track toward achieving their NTD disease control and elimination goals, and community perceptions have remained positive. The purpose of this article is to share the lessons and best practices that have emerged from the adoption of strategies to limit the spread of the novel coronavirus during MDA and other program activities.

Comparison of platforms for testing antibodies to Chlamydia trachomatis antigens in the Democratic Republic of the Congo and Togo.

Trachoma, caused by repeated ocular infection with Chlamydia trachomatis (Ct), is targeted for elimination as a public health problem. Serological testing for antibodies is promising for surveillance; determining useful thresholds will require collection of serological data from settings with different prevalence of the indicator trachomatous inflammation-follicular (TF). Dried blood spots were collected during trachoma mapping in two districts each of Togo and Democratic Republic of the Congo. Anti-Ct antibodies were detected by multiplex bead assay (MBA) and three different lateral flow assays (LFA) and seroprevalence and seroconversion rate (SCR) were determined. By most tests, the district with > 5% TF (the elimination threshold) had five-sixfold higher seroprevalence and tenfold higher SCR than districts with < 5% TF. The agreement between LFA and MBA was improved using a black latex developing reagent. These data show optimization of antibody tests against Ct to better differentiate districts above or below trachoma elimination thresholds.

[Satisfaction of the beneficiaries of compulsory health insurance for public officials and assimilated employees in Lomé, Togo]. / Satisfaction des bénéficiaires du régime obligatoire d'assurance maladie des agents publics et assimilés à Lomé, Togo.

INTRODUCTION: In February 2011, the Togolese Government established a compulsory health insurance for public officials and assimilated employees. Four years later, this study investigated the satisfaction of beneficiaries of this insurance plan in Lomé. METHODS: The survey was conducted among a sample of beneficiaries using an anonymous face to face questionnaire outside eight health care facilities. The analysis of survey responses allowed measuring the degree of satisfaction. Quantitative data were described using median and extended interquartile range (IQR) and qualitative data were transcribed verbatim. RESULTS: Out of 288 subjects invited to participate, 279 agreed to participate of whom 58% were women and 88% were officials in active employment. The average age of the participants was 38 years (IQR: 30-47). A very large majority of respondents (93.5%) considered this health insurance "satisfactory". The mean overall satisfaction score was 6/10 (min: 5, max: 9). The main elements of dissatisfaction involved the refusal of care to those people with long-term illnesses (84% dissatisfied), the complexity of administrative formalities (84% dissatisfied) and care delays (67% dissatisfied). CONCLUSION: The very high level of satisfaction promotes the maintenance and the development of this health insurance in Togo. However, the elements of dissatisfaction should receive prompt attention and genuine efforts should be made to correct them.

Prevalence and factors associated with overweight and obesity among children from primary schools in urban areas of Lomé, Togo.

OBJECTIVE: Overweight and obesity in childhood are serious public health issues, both in developing and developed countries. The present study aimed to ascertain overweight and obesity prevalence rates among Togolese schoolchildren in Lomé, Togo, and their correlation with physical activity, socio-economic conditions and eating habits. DESIGN: Cross-sectional survey conducted in December 2015. Overweight and obesity were defined using age- and sex-specific BMI cut-off points of the International Obesity Task Force. Physical activity, socio-economic conditions and eating habits were assessed with a standardized questionnaire. Specially trained medical students interviewed children and collected the data. After bivariate regression analyses, factors associated with overweight/obesity were identified by multivariate logistic regression. Statistical significance was two-sided P<0·05. SETTING: Lomé, Togo. SUBJECTS: Representative sample of 634 children (288 boys, 346 girls), aged 8-17 years, who were studying in primary schools. RESULTS: Overweight and obesity respectively affected 5·2 and 1·9 % of children surveyed. Watching television (>4 h) on weekends (OR; 95 % CI: 3·8; 1·2, 12·0, P=0·02) and medium dietary diversity score (3·0; 1·1, 8·1, P=0·03) were independently associated with overweight/obesity in a multivariate regression model. Eating breakfast in the school cafeteria (0·2; 0·1, 0·8, P=0·03) and eating fruits (0·4; 0·1, 0·9, P=0·03) significantly reduced the risk of overweight/obesity. CONCLUSIONS: Overweight and obesity prevalence were linked with sedentary behaviour and non-optimal food diversity. Promoting physical activity and fruit consumption should be explored as interventions to reduce and prevent overweight and obesity in Lomé schoolchildren. In addition, preventive approaches in the social environment of children should be considered.

[Stigma and discrimination experienced by people living with HIV in Togo, in 2013]. / Discrimination et stigmatisation vécues par les personnes vivant avec le VIH au Togo en 2013.

BACKGROUND: Stigma and discrimination experienced by people living with HIV (PLWHA) prevent and delay access to prevention and treatment services. The aim of this study was to describe the patterns of stigma and discrimination experienced by PLWHA in Togo and to identify the associated factors. METHODS: A cross-sectional study was conducted in 2013 among PLWHA in Togo in order to collect data on stigma or discrimination experiences. Univariate and multivariate analyses were performed to identify associated factors. RESULTS: A total of 891 PLWHA were interviewed, including 848 (95.2%) receiving antiretroviral therapy. External stigma (37.9%) was the major form of stigmatization followed by internalized stigma (35.4%). The main features of external stigma were gossip (36.5%) and issues to access education (36.0%). Internalized stigma mainly consisted of a feeling of guilt (37.6%) and self-devaluation (36.0%). In univariate and multivariate analysis, female gender was significantly associated with stigma (aOR = 1.73, 95% CI [1.08-2.77]). Of the 891 PLWHA, 75 (8.4%) reported a violation of their rights. Finally 27 (4.1%) were discouraged from having children by a health professional because of their HIV status. CONCLUSION: Stigma affects more than one-third of PLWHA in Togo, more particularly females. It appears necessary to design new interventions and integrate psychosocial care in the management of PLWHA, in addition to antiretroviral therapy.

Emergence of Lassa Fever Disease in Northern Togo: Report of Two Cases in Oti District in 2016.

BACKGROUND: Lassa fever belongs to the group of potentially fatal hemorrhagic fevers, never reported in Togo. The aim of this paper is to report the first two cases of Lassa fever infection in Togo. CASE PRESENTATION: The two first Lassa fever cases occurred in two expatriate's health professionals working in Togo for more than two years. The symptoms appeared among two health professionals of a clinic located in Oti district in the north of the country. The absence of clinical improvement after antimalarial treatment and the worsening of clinical symptoms led to the medical evacuation. The delayed diagnosis of the first case led to a fatal outcome. The second case recovered under ribavirin treatment. CONCLUSION: The emergence of this hemorrhagic fever confirms the existence of Lassa fever virus in Togo. After a period of intensive Ebola virus transmission from 2013 to 2015, this is an additional call for the establishment and enhancement of infection prevention and control measures in the health care setting in West Africa.

Condom use and associated factors among men who have sex with men in Togo, West Africa.

INTRODUCTION: In 2011, the prevalence of HIV among men who have sex with men (MSM) in Togo was estimated at 19.6% compared to 3.4% in the general population. This study aimed to describe condom use and associated factors among MSM in Togo. METHODS: In 2011, a cross-sectional survey was conducted using the snowball sampling method among MSM in Togo. This study enrolled MSM aged 18 years and above who reported having sexual contact with other men within the last 30 days. A standardized survey form was used for data collection, and multivariate analyses were performed. RESULTS: A total of 724 MSM were included in this study. The median age was 25 years [22-28], 90.3% had at least a secondary school level. The sexual practices during the last sexual encounter with another man included: insertive anal sex (62.2%), receptive anal sex (56.6%), oral sex (33.8%) and oral-anal sex (8.6%). A condom was used during the last insertive and receptive anal encounters in 78.4% and 81.2% of the time, respectively. In multivariate analysis, condom use was positively associated with previous participation in HIV/STD prevention activities (aOR=1.72; 95% CI=[1.09-2.71]), with the consideration of the last sexual partner as a casual one (aOR=1.87; 95% CI=[1.24-2.82]) and with having at least a secondary school level (aOR=2.40; 95% CI=[1.22-4.69]). CONCLUSION: One out of five MSM did not use a condom during the last anal encounter with another man. HIV prevention programs in Africa should develop specific interventions targeting MSM to reduce the incidence of HIV in this hidden population.
