Mass public testing for coronavirus could stop people from self-isolating and social distancing during the pandemic, scientists have warned.
There is a risk that people who have had Covid- 19 and are now immune will return to normal life and be followed by others who are still at risk of catching the deadly virus.
Another concern is that people who are fed up with isolation will go out and simply claim to have had the infection, according to scientists.
However, mass testing has worked for countries like South Korea which saw cases of Covid-19 sharply drop without going into lockdown.
