Having established the goal of eliminating transmission of gambiense human African trypanosomiasis (g-HAT) to humans, the HAT-e-TAG considered which elements should be developed to assess this goal.
HAT diagnosis relies on laboratory techniques because clinical signs and symptoms are unspecific. Serodiagnostic tests exist only for Tbg and are based on the detection of specific antibodies, thus they are not confirmatory of infection. With the current low disease prevalence, the positive predicti
...
ve value of serological tests is particularly low. Field-applicable tools include the card agglutination test for trypanosomiasis (CATT) used mainly in active screening by specialized mobile teams, and the rapid diagnostic tests that are more suitable for individual testing at point-of-care.

rican Trypanosomosis (PAAT). The Atlas database is built by the systematic collection of information around every HAT case detected worldwide, actively or passively, in endemic and non-endemic countries, and also on the surveillance activities carried out per village. The data are aggregated by year, by location and by some other parameters. All cases and activities are georeferenced at the village level to within an average accuracy of about 1.4 km. The Atlas contains complete information since the year 2000 from the 25 countries reporting at least one HAT case

Trachoma is the world’s leading infectious cause of blindness. It is one of 18 neglected
tropical diseases (NTDs) that affect over one billion of the world’s poorest people.

The main aim of IRS is to kill vectors before they are able to transmit pathogens to humans. When carried out correctly, IRS has his

Antimicrobial resistance (AMR) is a global public health crisis that resulted in 1.14 million deaths in 2021. According to the Institute for Health Metrics and Evaluation estimates, 96 416 of thes

e deaths occurred in the World Health Organization (WHO) Eastern Mediterranean Region. All 22 countries/territories in the Eastern Mediterranean Region are enrolled in the global AMR
surveillance system, and 17 countries/territories reported data in 2024 (for the year 2023). The total number of isolates reported to the system increased sixfold between 2017 and 2022, but the proportion of blood isolates is relatively very low. Most of the data come from public sector laboratories or hospitals, although the private sector has increased its participation in some countries/territories recently. Three pathogens account for three quarters of all the reported pathogens – Escherichia coli
(26%), Klebsiella pneumoniae (23%), and Staphylococcus aureus (22%).
