Winter officially began Thursday, and with the cold season comes an expected rise in rates of flu and Covid, said Dr. Mandy Cohen, the director of the Centers for Disease Control and Prevention.
The U.S. is seeing a "sharp increase" in flu levels right now, particularly in the south, Cohen said Wednesday in an interview. Covid cases also appear to be climbing nationally, she said, while cases of respiratory syncytial virus, or RSV, seem to have reached their highest point this season.
"Weβre seeing RSV peak a bit sooner, but we do not believe weβre near yet at the peak of flu or Covid," Cohen said.
As of Dec. 9, the weekly number of positive RSV tests in the U.S. had fallen around 16% compared to the previous week.

The pattern is different from that of last year, Cohen said, when the three viruses "all seemed to peak around the same time."
