Bad news

The majority of coronavirus infections may be spread by people who have recently caught the virus and have not yet begun to show symptoms, scientists have found.

An analysis of infections in Singapore and Tianjin in China revealed that two-thirds and three-quarters of people respectively appear to have caught it from others who were incubating the virus but still symptom-free.

The finding has dismayed infectious disease researchers as it means that isolating people once they start to feel ill will be far less effective at slowing the pandemic than had been hoped.
