First Covid-19 reinfection confirmed in the US

Researchers in the US have reported the country’s first confirmed case of Covid-19 reinfection.

A 25-year-old man with no known immune disorders or underlying conditions was infected with Covid-19 on two separate occasions, according to a study published in the Lancet Infectious Diseases journal.

While the authors said further research was required, they added the findings indicate previous exposure to the virus may not guarantee total immunity, and that all individuals should comply with control measures.

It is the fifth confirmation of reinfection worldwide, researchers said, with at least four other cases confirmed in Belgium, the Netherlands, Hong Kong, and Ecuador.
