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 Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used.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

It is too early to know the full impact of COVID-19 on Africa. To date the experience has been varied. There are causes for concern, but also reasons for hope. Early estimates were pessimistic regarding the pandemic’s impact on the continent. But the relatively low numbers of COVID-19 cases report...ed thus far have raised hopes that African countries may be spared the worst of the pandemic. While the virus is present in all African countries, most countries have recorded fewer than 1,000 cases. The African Union acted swiftly, endorsing a joint continental strategy in February, and complementing efforts by Member States and Regional Economic Communities by providing a public health platform.

“Because we struggle to survive” Child Labour among Refugees of the Syrian Conflict | This study provides pertinent first-hand information on the reality facing Syrian children who are working either in their homeland, the neighbouring countries or elsewhere in Europe. Syria's civil war is the w...orst humanitarian crisis of our time. Hundreds of thousands of people - adults and children alike - have been killed. Two thirds of all Syrians have lost their homes and their livelihoods. Millions of Syrians have been uprooted from their home communities and forced to flee within their country or to neighbouring countries. The consistent spill-over has drawn global attention not just to the humanitarian crisis facing both local communities and national governments but also to the economic and social strain. The bloodshed wreaked by the different parties continues. The suffering deepens. Approximately half of the Syrian refugees and displaced persons are children and young people who suffer from a double-vulnerability: as children and as migrants or refugees.
