Lack of Covid testing leaves researchers blind to evolution patterns, WHO warns

William Rodriguez, who heads the global diagnostics alliance FIND, also decried that many governments in recent months simply stopped looking for Covid cases.

The plunging testing rates came despite the fact that there is now more access to accurate testing than ever before.

The Covid-19 pandemic has officially caused more than 6 million deaths since the virus first surfaced in China in late 2019, but the true toll is believed to be at least three times that high.

While many countries have been removing measures and trying to move back to a semblance of normality, the WHO stresses that the pandemic is still not over.
