Is a 'quademic' swirling? What you should know about flu, RSV, COVID and norovirus

USA Today quotes Thomas Russo in an article about the “quademic” of  flu, COVID-19, RSV and norovirus. "We haven't seen the (COVID) peak we have seen in previous winters," Russo said. "Peaks in RSV and influenza have been greater, and we may see a peak in COVID in upcoming weeks." Russo said it is unlikely that someone would get two of the infections at the same time, and that "to get all four is certainly unlikely, particularly if you are vaccinated."
