COVID, RSV, Influenza all at high levels during holiday season

COVID, RSV, the flu, the 3 respiratory viruses that are causing the most trouble this holiday season. "Influenza is rising or is at really high levels across much of the United States. We have cases of COVID and RSV or respiratory syntactical virus, both of which have sort of stabilized, they aren't really increasing but they're still at relatively high levels," said Andrew Pekosz, a professor of microbiology at Johns Hopkins. For a while, respiratory viruses didn't spread as easily because of COVID precautions.
