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 giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic 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 Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used.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.

The HIV drug resistance report 2021 summarizes findings from 38 countries that had finalized the surveys by the time of this report and shared data with WHO.
Pretreatment HIVDR to non-nucleoside reverse-transcriptase inhibitors (NNRTI) can affect more than 10% of adults starting therapy and is fo...und up to 3 times more often in people who had previous exposure to antiretroviral drugs. In addition, nearly half of infants newly diagnosed with HIV has HIVDR to NNRTI before initiating treatment.The high levels of observed NNRTI pretreatment HIVDR among emphasize the need to fast-track the transition to WHO-recommended dolutegravir-based ART.

The Government of Botswana’s SRH Policy Guidelines and Service Standards document provides the framework for developing a responsive strategy and an implementation plan for SRHR and HIV&AIDS Linkages and Integration. The global call on governments to demonstrate commitments to intensify linkages b...etween sexual and reproductive health and HIV&AIDS at the policy and programme level is therefore an added opportunity for the government to review the current service provision model and optimize current resources to provide more integrated, comprehensive coordinated SRHR and HIV&AIDS services.
