Evidence on reinfection risk was limited prior to this study."Little is known about protection against SARS-CoV-2 repeat infections, but two studies in the U.K. have found that immunity could last at least 5 to 6 months after infection," the authors note.
By the end of 2020, more than 10 million people had undergone free polymerase chain reaction testing by the Danish government or through the national TestDenmark program. As with the previous research, this study also indicates that an initial bout with COVID-19 appears to confer protection for at least 6 months. The researchers found no significant differences between people who were followed for 3 to 6 months and those followed for 7 months or longer.To account for possible bias among people who got tested repeatedly, Michlmayr and colleagues performed a sensitivity analysis in a subgroup.
Risk for reinfection with SARS-CoV-2 is generally low — but it's higher among adults aged 65 and older — according to a population-based study from Denmark published in The LancetAsked to speculate whether the results would be different had the study accounted for variants, Hirschwerk said,"It depends upon the variant, but certainly for the B.1.
Even young people can catch it again
OOHH..INTERESTING..😮
