MEDICAL INSURANCE
You must purchase medical insurance as soon as you arrive in Belarus. Your health insurance from your home country is unlikely to be valid in Belarus, thus you will have to get one. It will cover any unexpected medical bills, so you won't have to worry about paying if something goes wrong on your trip. Although the cost is reasonable, this is a definite necessity for your stay. The charge was one euro per day during my stay (October 2018). As a result, you'll require 7 euros/8 USD for a week.
All international visitors to Belarus are required to have insurance. It could be "Belgosstrakh" insurance, which you can get at the border or at the airport. The insurance can be paid in Belarusian or Russian rubles, dollars, or euros. Insurance costs vary based on the length of your stay. For instance, 30 days of insurance will set you back 31 euros.
You should check ahead of time to see if a visa is required for your stay. Belarus' government has been gradually opening up to tourism in recent years, beginning with a 5-day visa-free regime that has recently been expanded to 30 days. You will not require a visa if you are from an EU nation or the United States.
