Medical facilities on the island are not always up to par with health care standards of your home country. Falling ill can sometimes result in major medical fees. Therefore, it is advised to buy travel/health insurance, as this will ensure peace of mind in emergency situations.

Malaria can be a risk, mostly near the Kingston area. The island had been malaria free for years, until incidents in recent years.

The water quality is generally good and safe to drink. If staying in the island's two major cities, Kingston and Montego Bay, the water is of the quality you would most likely find in your home country. However, Jamaicans generally boil their water, and it is likely best to follow the Jamaican people's example. Water service in rural areas can sometimes go out for several hours at a time. Individuals in rural areas have their own water tanks, which catch water when it rains, so be ready to draw from a tank instead of turning a pipe. Bottled water such as Wata (a local brand), Aquafina and Deer Park are widely available.

Be cautious of the water quality at public swimming beaches, such as "Walter Fletcher Beach" in Montego Bay, which some locals call "dump-up beach", situated near the north gully. Large amounts of solid and human waste flush down the gully during storm events. The water flowing down Dunn's River Falls has also been said to contain high amounts of coliform bacteria, indicating fecal contamination.
