Nearly half of insured American adults say they’re not confident they could handle costs associated with coronavirus treatment, according to a recent Healthcare.com and YouGov poll. The survey polled nearly 2,500 Americans ages 18 and over.

Of those who think they can’t afford to be sick, 23% aren’t very confident they could deal with coronavirus treatment and screening costs without going into debt. And 25% of respondents aren’t at all confident.

The lack of confidence in affording coronavirus costs is more prominent among younger Americans. Of those ages 18 to 34, 35% aren’t confident they could deal with costs compared to 24% of those ages 55 and older, according to additional poll data Healthcare.com provided to Business Insider.
