A global review that statistically combined results from nearly a hundred studies, involving over 29 million people, has found 40.5 per cent of those with confirmed COVID-19 didn’t show any symptoms. Of all people tested, only a tiny proportion - 0.25 per cent - lacked symptoms, reflecting the targeting of tests to those with signs of illness. The authors say more screening for asymptomatic infection is required in communities, especially in places that have successfully controlled the virus.
