The World Health Organisation (WHO) says it has issued guidance advising people on how to test themselves for the coronavirus, months after critics said the lack of recommendations was compromising efforts to stop the pandemic in poor countries, reports AP.

At a press briefing, WHO director-general Tedros Adhanom Ghebreyesus said the agency was concerned that some countries are dramatically reducing their Covid-19 testing as the virus appears to recede in some parts of the world.

Self-testing remains a vital tool in our fight against Covid-19 as part of a comprehensive strategy, Tedros said, adding that abandoning testing would cripple officials' efforts to track the disease.
