Medical insurance for traveling abroad.

Generally, an insurance policy is not mandatory for traveling abroad. However, the rules of a particular country may stipulate otherwise.

At the same time, the Ministry of Foreign Affairs of Ukraine (the "MFA") recommends taking out full medical insurance to cover expenses related to possible emergencies, including COVID-19 treatment, and accident insurance.  

You can find the latest information on the rules of entry to different countries of the world on the MFA portal, available via the link.
