"Tripledemic" in U.S. could bring deluge of patients to hospitals

The U.S. could very well face what has been dubbed a "tripledemic" this winter, with cases of COVID-19, the flu and a virus called respiratory syncytial virus (RSV) surging at the same time. 

Cases of RSV are rising quickly in young children, who typically contract the virus by the time they're 3, but were shielded from it and other viruses during pandemic lockdown periods. 

"Pediatric ICUs around the country, many parts of it, are full," said CBS News medical contributor Dr. David Agus. Most hospitalizations now are related to influenza and RSV, not COVID-19, he added.
