Tap water in Cuba is not reliably safe to drink and outbreaks of cholera have been recorded in recent years. Bottled water called Ciego Montero rarely costs more than CUC$1, but is sometimes not available in small towns. Stock up in the city if you're going on a long bus or car journey.
Check you are up-to-date on routine vaccinations before you go to Cuba. Also, check travel advisories on your country's government website regarding current health warnings.
Since May 2010, Cuba has made it obligatory for all foreign visitors to have medical insurance. Random checks are made at the airport, so ensure you bring a printed copy of your policy.
Should you end up in hospital, call Asistur for help with insurance and medical assistance.
Outpatient treatment at international clinics is reasonably priced, but emergency and prolonged hospitalization gets expensive (the free medical system for Cubans should only be used when there is no other option).
Should you have to purchase medical insurance on arrival, the costs are from CUC$3 per day for coverage of up to CUC$25,000 in medical expenses (for illness) and CUC$10,000 for repatriation of a sick person.
Most of Cuba's specialist hospitals offering services to visitors are based in Havana.
