Covid infection largely protects health workers
Healthcare workers who have recovered from Covid-19 are largely protected against falling ill again for at least five months, a British study has found, but researchers warned some people could still carry and transmit the virus.
Researchers from Public Health England's SIREN study detected 44 potential reinfections out of 6,614 participants, who had already tested positive for antibodies in a five-month period between June and November 2020.
In their first published report -- which has not yet been peer reviewed -- the authors said this represents an 83 percent rate of protection from reinfection.
But they warned that although antibodies may confer some protection from becoming ill with Covid-19, early evidence from the next stage of the study suggests that some of these individuals carry high levels of virus and could continue to transmit it to others.
