AMSTERDAM/BRUSSELS—Two European patients are confirmed to have been re-infected with the coronavirus, raising concerns about people’s immunity to the virus.

The cases, in Belgium and the Netherlands, follow a report this week by researchers in Hong Kong about a man there who had been re-infected with a different strain of the virus four and a half months after being declared recovered—the first such re-infection to be documented.
