WHO policy brief: COVID-19 testing, 14 September 2022

The World Health Organization (WHO) recognizes the challenges countries face for maintaining their COVID-19 response while addressing competing public health challenges, conflicts, climate change and economic crises. It remains critical for national programmes to continue to offer testing for COVID-19 in line with three main objectives: reduce morbidity and mortality through linkage to prompt care and treatment, reduce onward transmission and track the evolution of the epidemic and the virus itself.
