Covid tests 'could be picking up dead virus' Scientists say a positive coronavirus result does not guarantee that someone is infectious. BBC News

The main test used to diagnose coronavirus is so sensitive it could be picking up fragments of dead virus from old infections, scientists say.

Most people are infectious only for about a week, but could test positive weeks afterwards.

Researchers say this could be leading to an over-estimate of the current scale of the pandemic.

But some experts say it is uncertain how a reliable test can be produced that doesn't risk missing cases.

But people of color have been disproportionately affected by Covid-19, the illness caused by the coronavirus, and recent studies have renewed concern about the susceptibility of children in these communities.
