LOUISVILLE, Ky. (WAVE) — Health experts believe one of the main culprits behind the spread of COVID-19 in the U.S. has been "super-spreader incidents."
These types of events happen when a single person infects a large number of other people.
It can happen at events like birthday parties, conferences, and choir practices.
A University of Louisville doctor also says more COVID-19 infections are coming from the 18-45-year-old age range.
People in that age group reportedly have a tendency to be less symptomatic or have no symptoms, and therefore, are more likely to spread the virus without realizing it.
