2023 is seeing intense heatwaves. According to a July 2023 briefing by the World Meteorological Association temperatures will frequently reach above 35–40°C in many places across the Mediterranean region, with temperatures in the Middle East and southeastern Türkiye reaching up to 45°C and, in ...North Africa, 44–49°C. April–May 2023 also saw temperature records broken across many parts of Asia, including Thailand, Laos and Myanmar.
The IPCC predicts that 420 million people will be exposed to extreme heat and heatwaves in the near future. Hundreds of thousands of people die from preventable heat-related causes each year, while temperature extremes and wildfires cause devastation to lives and livelihoods. According to the WMO, ‘heatwaves are amongst the deadliest natural hazards [and] heat is a rapidly growing health risk’.

Senegal is on course to meet the global target for under-five overweight, but is off course to meet the targets for all other indicators analysed with adequate data.
Almost half (46%) of the world’s 1.7 million children living with HIV were not on treatment in 2020 and 150 000 children were newly infected with HIV, four times more than the 2020 target of 40 000
How we respond both now and going forward will help mitigate the impact of COVID-19, and to the extent possible preserve children’s rights to Survive, Learn, and Be Protected. We will focus our efforts on the most critical work essential to maintaining these commitments to the extent possible.

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 Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used.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.
