Scientists say Hong Kong man got coronavirus a second time

University of Hong Kong scientists claim to have the first evidence of someone being reinfected with the virus that causes COVID-19.

Genetic tests revealed that a 33-year-old man returning to Hong Kong from a trip to Spain in mid-August had a different strain of the coronavirus than the one he’d previously been infected with in March, said Dr. Kelvin Kai-Wang To, the microbiologist who led the work.
