The quad-demic consists of a surge in infections caused by the flu, COVID-19, the respiratory illness RSV and norovirus, commonly called the stomach flu, according to the outlet.
Headlines about the quadruple threat emerged just weeks before President- elect Donald Trump takes office, fresh after talk about the risk of bird flu fell flat.
