Many people who celebrated with family, with friends over Thanksgiving will find themselves in the hospital in icus over Christmas and new years.

I think people aren't taking this seriously enough. Reporter: One doctor saying, quote, we are rounding the corner into a calamity urging anyone who spent thing with people outside their own households to quarantine for 14 days. Don't go into work, pull your kids out of school for that period of time because you do not want to be spreading coronavirus inadvertently to people around you. Reporter: And now from new York to California, a post Thanksgiving rush to get tested. Once you get back to your location, you should decrease unnecessary activities for about a week. And if you can get tested in three or five days, that's also a very good idea. Reporter: In Atlanta Cody George says he tested negative for the virus before taking off to see family in Ohio. And won't go through the Sam hassle again for Christmas. It was a lot of stress to be like, okay, make sure that before my test a couple days I'm not seeing anybody, after my tetay in the basement, do all these other things. Reporter: Now if you want to cancel your flight amid the pandemic, you can do so and get an airline credit for future travel even if you got a nonrefundable ticket.
