Flu season would be wrapping up right about now in a typical year.
But medical experts say it's basically vanished across the country -- replaced by COVID-19.
Doctor Maryann Lauletta, who specializes in treating elderly patients in New Jersey, says there are some ideas that might explain the disappearance of the flu.
"I do believe that the masks and the hand washing are a big factor as well as the social distancing. However there are other factors at play and we will never know which one had the biggest impact because I don't know that anybody has done this study you know, remote work, schools being closed, decreased global travel, decreased capacity in places where people do gather," she says.
Lauletta says more people might have been gotten a flu shot, too, since more vaccine doses were distributed in the fall.
Health officials had said they were worried about a "twindemic" of flu and COVID but it never happened.
