Can you get the coronavirus twice? Scientists don’t know for sure yet, but they believe it’s unlikely.
Health experts think people who had COVID-19 will have some immunity against a repeat infection. But they don’t know how much protection or how long it would last.
There have been reports of people testing positive for the virus weeks after they were believed to have recovered, leading some to think they may have been reinfected. More likely, experts say people were suffering from the same illness or the tests detected remnants of the original infection. There’s also the chance tests could have been false positives.
Scientists say there has been no documented instance of a patient spreading the virus to others after retesting positive.
With similar viruses, studies have shown that people could fall sick again three months to a year after their first infections. It’s still too early to know whether that’s also possible with the coronavirus.
It’s very much emerging science, said Dr Philip Landrigan, director of the global public health program at Boston College. (AP)
