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 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 guideline provides updated, evidence-informed guidance on the percentage of total fat in the diet to reduce the risk of unhealthy weight gain.
This guideline is intended for a wide audience involved in the development, design and implementation of policies and programmes in nutrition and pub...lic health. This guideline includes a recommended level of total fat intake which can be used by policy-makers and programme managers to address various aspects of dietary fat in their populations through a range of policy actions and public health interventions.
The guidance in this guideline replaces previous WHO guidance on total fat intake, including that from the 1989 WHO Study Group on Diet, Nutrition and the Prevention of Chronic Diseases and the 2002 Joint WHO/FAO Expert Consultation on Diet, Nutrition and the Prevention of Chronic Diseases. The guidance in this guideline should be considered in the context of that from other WHO guidelines on healthy diets.

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.
Tsetse traps and targets (insecticide-impregnated screens) function by attracting the flies to a device that collects and/or kills them. Traps can be used for entomological surveillance, and also for control. Targets are simpler than traps, but are not used for surveillance. They are impregnated wit...h biodegradable insecticides in order to kill any flies that alight on them. Traps can also be impregnated with insecticides. Traps and targets can both be used to eliminate a fraction of the tsetse population.

The IAPB School Eye Health Workgroup has released these guidelines to help deliver standardised comprehensive eye health services to more than 700 million children attending schools around the world. These guidelines direct the planning and implementation of school eye health initiatives for policym...akers, health authorities, and related professionals. They emphasize effective, efficient, and sustainable programs, particularly in low- and middle-income countries. Monitoring and evaluation should be planned from the outset, and existing local guidelines should be integrated.
