Why don't some people get COVID?

MINNEAPOLIS — Every so often you run across a “NOVID.”

Dr. Jill Foster is a pediatric infectious disease specialist at the University of Minnesota Medical School.

“I think most of them probably did [have COVID-19],” Foster said.



She says the NOVID group falls into four categories:

1: Genes. This is the smallest group, comprised of people who were born with an immunity to the virus.

2: Previous immunity from some other kind of coronavirus.

3: People who had an asymptomatic case.

4: People who have just been super careful.

If you’re curious, there is an antibody test you can take to see if you’ve ever had COVID-19, but Dr. Foster says they’re not always reliable.

The CDC thinks COVID-19 has infected 70 percent of the U.S. population. But because so many cases are asymptomatic, those numbers could be higher.
