Coronavirus immunity: Can you catch it twice?
Scientists from Hong Kong recently reported on the case of a young, healthy man who recovered from a bout of Covid-19 only to be re-infected more than four months later. Using genome sequencing of the virus, they could prove he caught it twice because the virus strains were different.
Experts say re-infection isn't surprising, but it's likely to be rare, and larger studies are needed to understand why this might happen.
