Medical, hospital and dental care is free for all Cubans. In emergencies, medical care is also free for tourists. Medical insurance is available. You should take care, however, about what you eat and drink. Do not drink tap water and keep clear of ice.
Water is purified in the main tourist areas.
Bottled water is available everywhere. Use boiled or sterilized water for making tea or cleaning teeth. Do not swallow water in hotel swimming pools. Money Cuban pesos are the official currency, but U.S. dollars are accepted everywhere and are the preferred method of payment. Credit cards and traveler's checks issued by U.S. companies are not negotiable.
