Facebook posts shared thousands of times claim that holding your breath for more than 10 seconds is an effective test for the novel coronavirus, and that drinking water regularly can prevent the disease. The claims are false; the World Health Organization and other experts said there was no evide...nce to support these claims.

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 speed of developing diagnostics for SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), has been quite remarkable. Diagnostics have focused on nucleic acid amplification testing (NAAT) to identify infected individuals in acute-phase disease for timely implementation of mitiga...tion strategies and case management. More and more immunodiagnostics, mostly rapid diagnostic tests, are being made available as an alternative to NAATs. This type of test can be used out-of-laboratory conditions at large scale.

WHO recommends artemisinin-based combination therapies for treating uncomplicated malaria, alongside studies to monitor treatment effectiveness. Given the threat of antimalarial resistance, including partial resistance in several African countries, molecular tools are vital for tracking resistance. ...In 2015, WHO launched the External Quality Assessment scheme for nucleic acid amplification testing to ensure reliable lab results. Coordinated by WHO and operated by the United Kingdom National External Quality Assessment Service for Parasitology, the scheme provides quality-controlled specimens and reports to help improve testing accuracy. Experts recently discussed expanding the scheme to include antimalarial resistance markers.
