The AP reports that flu has virtually disappeared from the U.S., with reports coming in at far lower levels than anything seen in decades. Experts say that measures put in place to fend off the coronavirus — mask wearing, social distancing, and virtual schooling — were a big factor in preventing a “twindemic” of flu and COVID-19. A push to get more people vaccinated against flu probably helped, too, as did fewer people traveling, experts said. The numbers are astonishing considering flu has long been the nation’s biggest infectious disease threat. In recent years, it has been blamed for 600,000 to 800,000 annual hospitalizations and 50,000 to 60,000 deaths. |
