Now Sweden has also received its first confirmed case of a person who fell ill with covid-19 twice.
A 53-year-old woman has become the first confirmed Swedish case of a covid-19 recurrence. This as he tested positive for the new corona virus in both May and August, writes Dagens Nyheter.
It is at Sahlgrenska University Hospital where the case has been established after analyzing the genome of the different virus strains in their entirety.
– In ten positions, the virus strain differed in May from the strain sampled in August. This means that we can say that there are two different infections and not the same one that was inactive, ST’s doctor Johan Ringlander tells the newspaper.
However, the findings are not that surprising, say the researchers, as occasional similar cases have been reported internationally.
However, Johan Ringlander does not believe that the case affects previous immunity assessments.
– In any case, this shows that the woman has been granted partial immunity. He had a very mild illness the second time around, indicating that he received some protection after his first infection.
