Coronavirus testing methods: What you need to know
Al JazeeraHere’s a look at various testing methods available as the WHO stresses the need to aggressively test for COVID-19. “We have a simple message to all countries – test, test, test,” Tedros Adhanom Ghebreyesus said last month in a press briefing on measures to fight the coronavirus pandemic in the Swiss city of Geneva. Elaborating further, Lesosky said the choice to implement mass testing for a new disease could very well take away the “capacity to diagnose or treat existing diseases”. “Anything was possible with enough funding”, she said, however, in the absence of it, the “benefits of mass testing need to be weighed carefully against potential drawbacks”. Moreover, Lesosky stressed: “mass testing … can be beneficial only if it is closely tied to public health programmes to limit further spread”, such as separate testing and treatment facilities and restriction of public gathering.
