The latest U.S. COVID-19 wave is taking its toll on some states’ intensive-care units (ICUs), with several parts of the country seeing outbreaks that are as bad as ever.

In 15 states, patients with confirmed or suspected COVID-19 are taking up more ICU beds than a year earlier, according to Department of Health and Human Services data. Colorado, Minnesota and Michigan have 41%, 37% and 34% of ICU beds occupied by COVID-19 patients, respectively, the data show.

The dramatic uptick means there’s proportionately less space in hospitals for those suffering from other potentially deadly ailments.
