Nearly 40% of those hospitalized with coronavirus are younger than 54: CDC There are at least 141 coronavirus-related deaths in the U.S.

As many spring breakers are still seen ignoring social distancing on the beaches of Florida, the Centers for Disease Control and Prevention is saying more younger people than initially thought are getting seriously ill due to the novel coronavirus.

Data released Wednesday night by the CDC shows that of the 508 patients known to have been hospitalized in the U.S. for COVID-19, about 20% of those were ages 20 to 44 and another 18% were between the ages of 45 and 54.

However, COVID-19 is still significantly more dangerous in older patients, as 80% of deaths associated with coronavirus are adults over the age of 65.

Less than 1% of coronavirus deaths were among patients aged 20-54, and zero patients under the age of 19 have died from the virus, the CDC report said.

These numbers don't provide the full context of underlying medical conditions in these patients.

White House coronavirus response coordinator Dr. Deborah Birx said she was concerned about reports out of Italy and France that more young people than expected were in ICUs with complications from COVID-19.

"We have not seen any significant mortality in the children, but we are concerned about the early reports coming out of Italy and France," Birx said during a briefing Wednesday. "Even if it's a rare occurrence, it may be seen more frequently in that group, and be evident now."
