What are the chances of falling sick with COVID more than once?

Michelle Barron, an infectious disease specialist with UCHealth [and professor of medicine at CU School of Medicine], wrote: “It is generally thought that you are unlikely to develop infection within 90 days after infection, but there are reports of individuals that had infection with omicron, that within two to 4 weeks, subsequently developed infection with BA.2 or some of the new variants.”

Connie Price with Denver Health, another infectious disease specialist [and professor of medicine at CU School of Medicine], said that in general, they are finding reinfection to be less severe. “Immunity does keep the virus a little more in control, likely not spreading as much virus,” said Price.
