July 2021. This publication brings together important clinical and programmatic updates produced by WHO since 2016 and provides comprehensive, evidence-informed recommendations and good practice statements within a public health, rights-based and person-centred approach.
These guidelines bring in

the most recent guidance on HIV testing strategies - the entry point for HIV prevention and treatment - and include comprehensive guidance on infant diagnosis. Key recommendations are presented on rapid antiretroviral therapy (ART) initiation and the use of dolutegravir. Updated recommendations are included on the timing of ART for people with TB, and the use of point-of-care technologies for treatment monitoring.

HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of g
...
iving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and public health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

horities using a reduced number of tests performed. The strategies are organized according to stages of transmission: (1) No cases reported or observed (Stage 0); (2) Imported cases (Stage 1); (3) Localized community transmission (Stage 2); (4) Large-scale community transmission (Stage 3). For each stage, the recommended approaches indicate which testing strategy to prioritize when there are severe limitations on laboratory testing. The document is based on the current epidemiology of COVID-19 and available molecular testing methods.
