Ukraine, the second-largest country in Europe in terms of land area, was moved this week to Level 4, the highest risk category under the CDC’s guidelines, from Level 3.
Earlier this month, the United States bumped up Singapore—a country with one of the highest vaccination rates in the world—to Level 4, and days before that, Belarus was deemed a Level 4 risk travel destination as well. Several other eastern European countries, including Romania, Moldova, and Bosnia and Herzegovina, were listed as Level 4 at around the same time.
In its bulletin for Ukraine, the federal health agency repeated several warnings to not travel to Ukraine unless one is fully vaccinated.
“Travelers should follow recommendations or requirements in Ukraine, including wearing a mask and staying 6 feet apart from others.”
“However, international travel poses additional risks, and even fully vaccinated travelers might be at increased risk for getting and possibly spreading some COVID-19 variants,” the CDC stated, without elaborating on how international travel would pose a greater risk than domestic travel.
Other countries that have been deemed Level 4 risks by the CDC include Austria, Bahamas, Botswana, Croatia, Greece, Ireland, Jamaica, Maldives, Switzerland, Thailand, Turkey, and the UK.
The designation comes as President Joe Biden signed an order on Oct. 25 imposing new vaccine requirements for most air travelers. Children younger than the age of 18 are exempt from the vaccine requirement.
“It is in the interests of the United States to move away from the country-by-country restrictions previously applied during the COVID-19 pandemic and to adopt an air travel policy that relies primarily on vaccination to advance the safe resumption of international air travel to the United States,” Biden’s proclamation reads.
Earlier this month, the CDC said it would accept any vaccine that’s authorized for use by the World Health Organization and that it will accept mixed-dose COVID-19 vaccines from travelers. That means that the Russian-made Sputnik V vaccine, which is heavily used by Latin American nations, is left off the list—amid an escalating row between Washington and Moscow.
