Turks and Caicos is a safe and healthy destination. The tap water may not be the best tasting, but it is safe to drink. Food-safety standards are high, and you rarely hear of upset stomachs or outbreaks of food poisoning. If you're feeling unwell, there are very good hospitals on both Provo and Grand Turk, as well as private health care clinics. Grace Bay Beach is usually clean and clear of any pests. There are no poisonous snakes in the Turks and Caicos, or any other animals that may be dangerous. Be sure not to go off the beaten path when exploring around the islands, however, as there are two trees in particular that act like poison ivy; they are difficult to identify, so it is best to stay out of the bush. In the water, be careful not to touch the coral, as a particular variety will burn your skin upon contact. You also must watch out for the lionfish; they are beautiful but very dangerous.
Most of the supplies are similar to those in the United Kingdom, United States, and Canada. You can find all the major brands that you are used to readily available around Provo, though prices are higher than at home. Over-the-counter drugs can be found at pharmacies and supermarkets, and even at small convenience stores. If you plan to travel beyond Provo, however, you may wish to stock up on necessities. Supplies may be slimmer on the less-developed islands. Sunscreen is especially expensive in the Grace Bay area; it's more reasonably priced at the IGA supermarket. If you need bug spray, get something with at least 25% DEET; off-brand spray is readily available. If you forget to buy it and find yourself at dusk with no-see-ums biting, ask your servers at the restaurant; there's a good chance they'll have a bottle on hand.
