WHO Guidelines for the Treatment of Human African Trypanosomiasis. Web Annex B
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. Confirmation of Tbg infection requires microscopic examination of body fluids necessitating specific training. The best performing methods are laborious and reach 85–95% diagnostic sensitivity when performed by skilled personnel.

The National Guidelines for HIV-1 Viral Load Laboratory Testing support plans to scale up viral load (VL) testing to reach the 90-90-90 targets in India. This phased scale-up includes the setup of 70 additional VL testing laboratories nationally. These guidelines include laboratory design considerat...ions, a summary of VL technologies, and specimen collection and handling as well as transportation and storage guidance. Quality control and quality assurance requirements are described as well as laboratory safety issues. The guidelines also describe the VL laboratory network to be developed with supply chain management issues and commodities described. Annexes include laboratory registers and reporting forms.

The 2020 recommendations for the programmatic management of TB preventive treatment are the first to be released under the rubric of WHO consolidated TB guidelines (Module 1 – Prevention). The WHO consolidated TB guidelines will gradually group all TB recommendations and will be complemented by ma...tching modules of a consolidated operational handbook. [1] The handbook will provide practical advice on how to put in place the recommendations at the scale needed to achieve national and global impact. The first handbook module in the series will be on the programmatic management of TB preventive treatment and will accompany the 2020 guidelines.

This document provides a generic model that can be used for risk assessment of exposure to insecticide products applied as indoor residual sprays. It aims to harmonize the risk assessment of such insecticides for public health use in order to generate comparable data for their registering and labell...ing by national regulatory authorities. The assessment considers both adults and children (all age groups) as well as people in the following specific categories:
- those preparing the spray;
- those applying the spray;
- residents living in the treated houses;
- residents who participate in preparing and applying insecticides.

Trachoma is the leading infectious cause of blindness worldwide. In April 2023, it was a public health problem
in approximately 40 countries, with an estimated 116 million people at risk and 1.5 million people affected
by the late blinding stage of the disease (1). About 84% of those at risk of tr...achoma are in the World Health
Organization (WHO)’s African Region; about 52% of those at risk of trachoma live in Ethiopia
