Previous Covid-19 infection may be protective for 5 months

Some might get re-infected & transmit the virus - should stay at home


Key points from article :

Most people who have had Covid-19 are protected from it for at least 5 months.

From June to Nov 2020 - 21,000 healthcare workers were included in a study.

Tested to see if they currently had the coronavirus or had it previously.

Of those who never had an infection 318 developed new infections.

But in 6,614 with antibodies only 44 potential new infections were seen.

Past infection was linked to 83% lower risk of getting the virus.

Will continue to monitor them for 12 months to see how long immunity lasts.

Will also look closely at cases with the new variant.

Prof Susan Hopkins, researcher said immunity from having Covid-19 is "not 100% protective"

Some people do catch Covid-19 again - and can infect others.

Should follow stay-at-home rules - whether or not they have had the virus.
