Mass coronavirus testing jis expanding in prisons.
Large numbers of inmates are testing positive, yet showing no symptoms. In state prison systems in Arkansas, North Carolina, Ohio and Virginia, 96% of 3,277 inmates who tested positive for the coronavirus were asymptomatic.
It suggests that people who are asymptomatic — contagious but not physically sick — may be driving the spread of the virus worldwide.
It also raises the question of whether testing of just people suspected of being infected is actually capturing the spread of the virus.
However, Reuters reports some people diagnosed as asymptomatic when tested for the coronavirus may go on to develop symptoms later.
