The World Health Organisation (WHO) reiterated its advice on Thursday that resources permitting, people exposed to the novel coronavirus should be tested even if they do not show immediate symptoms of infection.
The comments come after the US Centers for Disease Control and Prevention (CDC) said this week that people exposed to Covid-19 but not symptomatic may not need to be tested, surprising doctors and politicians and prompting accusations the guidance was politically motivated.
Maria Van Kerkhove, a WHO epidemiologist, said the UN agency recommended suspected cases and their contacts be tested, if possible, but the focus should be on people displaying signs of infection.
“Our recommendations are to test suspect cases, and we have definitions for those. We have definitions of contacts, and who contacts are of confirmed cases, and make recommendations that contacts, if feasible, should be tested regardless of the development of symptoms,” Van Kerkhove told a news briefing.
“The focus, though, is on those that do develop symptoms.”
