This gets top billing in the New York Times as the most important public occurrence in the world at the moment.
“An apparently young and healthy patient had a second case of Covid-19 infection which was diagnosed 4.5 months after the first episode,” University of Hong Kong researchers said Monday in a statement.
The report is of concern because it suggests that immunity to the coronavirus may last only a few months in some people. And it has implications for vaccines being developed for the virus.
The 33-year-old man had only mild symptoms the first time, and no symptoms this time around. The reinfection was discovered when he returned from a trip to Spain...
“Our results prove that his second infection is caused by a new virus that he acquired recently...” said Dr. Kelvin Kai-Wang To, a clinical microbiologist at the University of Hong Kong.
Given that there are millions of cases worldwide, it is not unexpected that a few, or even a few dozen, people might be reinfected with the virus after only a few months, experts have said.
