The U.S. State Department has issued a level 4 travel advisory for Hubei, which means “do not travel,” and is the highest warning level. A level 3 warning is in effect for the rest of China. “The biggest risk to traveling to China right now is the strict quarantine and travel bans the Chinese government has been enacting,” said Cioe-Pena. That said, if you must travel to China where there are cases of the virus, Amato recommends wearing a mask, washing hands often, and avoiding anyone that’s ill.
