The Ministry is warning the public in Jamaica that the Aedes aegypti mosquito breeds in any containerized environment that can hold water, such as drums, tires, buckets and animal feeding containers.
It depends more on the weather (how much rain there's been recently, whether there's much wind etc.) than on the location. But I would always expect mosquitoes in the Caribbean and go prepared for them. To me, that means taking a good repellent and using it religiously!
-Mosquitoes:In the evening mosquitos can be a problem. Jamaicans say the bites come from mosquitoes, ants and possibly sand fleas. So, before going to Jamaica, make sure to prepare yourself in advance and pack some long sleeves and pants.
Remember, Jamaica is a tropical paradise, but one thing that comes along with the tropics are mosquitoes. You have to remember to bring your bug spray. When shopping for the right one, I suggested getting the Unscented OFF spray; you want to make sure you are protected but not smelling like repellant.
Using insect repellent containing DEET, IR3535 or PICARIDIN. Using mosquito nets. Using mosquito deterrents such as electric mosquito destroyer mats, mosquito destroyer coils or specially formulated candles. Putting screens on windows and doors.
Seabather's eruption, also known as 'sea lice', is a rash that occurs after exposure to seawater that contains certain species of the larval form of the thimble jellyfish (Linuche unguiculata).
Health. HIV/AIDS is widespread in Jamaica. Take precautions if you're engaging in high-risk activities. Insect-borne illnesses, especially dengue, are common.
