“Because of the current situation in France, even fully vaccinated travelers may be at risk for getting and spreading COVID-19 variants,” one advisory reads.
Last week, the CDC urged against travel to Niger, Papua New Guinea, Poland, and Trinidad and Tobago.
The CDC also recently told airlines to share contact information for people entering the United States who have been in southern Africa, where the omicron variant was initially identified. Previously, the CDC had ordered airlines and aircraft operators to collect contact details on passengers and asked that they share it with federal health authorities “upon request,” to aid public health follow-up.
Worries that omicron could prove more transmissible and more resistant to vaccinations have triggered a cascade of travel restrictions around the world. But many experts question the value of travel bans, and the World Health Organization has urged against them.
