Required and recommended vaccinations
There are no natural sources of the spread of diseases on the island, the general epidemiological situation is extremely calm.

Sanitation and hygiene
All tap water in the country is practically safe to drink. However, it is recommended that you only use boiled or bottled water for drinking, brushing your teeth, or making ice (especially in the first week of your stay). Milk and dairy products are usually pasteurized and are harmless to consume. Meat, seafood and fish are considered quite safe, but still it is recommended to use them only after preliminary heat treatment, preferably hot. Vegetables should be thoroughly washed and pre-treated, and fruits should be peeled.

Solar Activity
The level of solar radiation is very high, so it is recommended to constantly apply sunscreen with a factor (SPF) of 15+ or more, wear sunglasses with glass filters, hats and light protective clothing, which should not be discarded when swimming, especially in the early days – a thin layer of water does not save from ultraviolet radiation at all. Also, an increased level of insolation and a special mineral composition of local water and products can lead to an exacerbation of certain diseases or an atypical effect of certain types of antibiotics, heart drugs (including drugs for high blood pressure), antihistamines and antidepressants. Increased precautions should be taken between 10:00 and 15:00, when radiation intensity is at its highest.

Do not underestimate the danger of tidal currents – when passing through the cracks and narrowness of the reefs, they form quite powerful and highly swirling currents that can seriously complicate swimming and diving under water. The ocean surf is also dangerous – even a small wave with a force of up to 2 points generates intense near-bottom “reverse currents” that can greatly complicate access to the rocky local coast. You should always choose places for swimming without surf or patrolled by lifeguards. The safest areas for swimming are usually marked, oddly enough, with red and yellow flags, in other cases it is recommended to follow the inscriptions on the coastal banners or consult with the locals.
