“Do not travel to China,” the U.S. State Department says. That’s Level 4 travel alert — the most strict.
Health officials have not advised people to worry about travel in general. Federal officials have not suggested anyone limit domestic travel.
U.S. officials are also expanding their health checks of inbound travelers from five airports to 20. (It is not yet clear which countries’ flights might be affected.) These inbound travelers are screened with a noncontact thermal device to check their temperatures, and officials look for coughing or sneezing. The passengers also answer questions about their travel, any possible symptoms, and whether they came in contact with infected people.
