Health officials nationwide are concerned there may be a dangerous ripple effect, and a potential surge in COVID-19 cases, following the Thanksgiving holiday weekend.

Despite the CDC encouraging people not to travel, airports such as Newark Liberty International Airport were still very busy over the weekend, as hospitalizations in the U.S. topped 93,000 -- a new high.            

Doctors are recommending precautions for people who did travel.

"Decrease the unnecessary activity,” says Adm. Brett Giroir, assistant secretary for health.

“If you have necessary activities, of course. But you've had a time where you could have been exposed, make really sure you adhere 100% to mask wearing, to avoiding crowds because you could inadvertently have gotten COVID and spread it. So, be careful during the week after your travel because you are at increased risk."

Officials also recommend getting a COVID-19 test before and after traveling.
