New evidence suggests young people are not as impervious to coronavirus as once thought.

A new report from the CDC shows nearly 40% of coronavirus patients sick enough to be hospitalized were ages 20-54. And nearly half of the 121 patients who were admitted to intensive care units were under 65.

"I think the younger people think they are invincible, and many of them have not curtailed their activities," says Dr. Randy DiLorenzo, of Northwell Health-Syosset Hospital. "I think what they have to think about contracting the virus and spreading the virus because this virus doesn't look at a person's age when it attacks them."

The CDC's findings serve to underscore the appeals both state and federal officials are making, asking young adults to refrain from large gatherings.

"These pictures of young people on beaches. These videos of young people saying this is my spring break. This is my time to party. This is so unintelligent and reckless," says Gov. Andrew Cuomo.

The new report also says nine people ages 20-64 died in the U.S. from the virus, though it doesn't include information about whether patients had underlying risk factors.

Salam Jalili, 20 of Syosset, says it's tough not hanging out with her friends, but for now, social distancing is key.

"We can still Facetime or whatever, so we're still able to talk to them and communicate," she says.
