Why do some people just not get infected with Covid? It’s an interesting question now that most people are more likely to HAVE had it than NOT have had it.
Scientists at the University of California, San Francisco say that some people have genetics that makes them “superdodgers.” That means that they can be exposed to the virus time and again and not show symptoms. These genetics are a mutation that causes some viruses to just slide off their cells “like water sliding off a glass window.”
The genetic mutation occurs in a gene called HLA. If a person has this, their chances of being asymptomatic is ten times higher than average.
Scientists have observed the superdodger phenomenon in other viruses before such as stomach flu, AIDS and other types of noroviruses.
