In updated guidance on COVID-19 testing strategies, the World Health Organization (WHO) says it does not currently recommend widespread screening of people without symptoms, citing the cost of such a strategy and its ineffectiveness.
“Widespread testing of asymptomatic populations, including through self-testing, is not currently recommended, based on lack of evidence on impact and cost-effectiveness of such approaches and the concern that this approach risks diverting resources from higher priority testing indications,” the guidance stated.
