Scientists Report First Confirmed Reinfection Case

Bloomberg reports:

A man was infected with the coronavirus after recovering from an initial bout in April in what scientists said was the first case showing that re-infection may occur within a few months. The 33-year-old’s second SARS-CoV-2 infection was detected via airport screening on his return to Hong Kong from Europe this month.

Researchers at the University of Hong Kong used genomic sequence analysis to prove that he had been infected by two different strains. The information technology worker didn’t develop any symptoms from his second infection, which might indicate “subsequent infections may be milder,” the researchers said.

“Our findings suggest that SARS-CoV-2 may persist in humans,” Kwok-Yung Yuen and colleagues said Monday in a paper accepted for publication in the journal Clinical Infectious Diseases.
