Before visiting Vanuatu, it is recommended that you get immunized against Hepatitis A and B, as well as typhoid fever.
Malaria is prevalent in certain parts of Vanuatu but not in Port-Vila. If you want to go outside of the resort regions, consult with your doctor beforehand. Malaria may not be prevalent, but you may come into touch with mosquito vectors and tourists from outlying islands who have malaria, especially during the rainy season and in hospitals. Dengue fever is also transmitted by mosquitos in Port Vila and elsewhere, especially during the rainy season. Be acquainted with the symptoms since there is no treatment for Dengue and Malaria, and the symptoms may be intermittent, leading to misdiagnosis. There are several local clinics on the outlying islands that can test you for Malaria, so find out where they are. Malaria preventive medications include adverse effects that may interfere with sun exposure, scuba diving, overall stability, and digestion.
The tap water in Port Vila is safe to drink, but it should be avoided elsewhere. Check with local customers. Outside of the major cities, bottled water is not accessible. Outside of the major cities, fizzy drinks but not beer may be accessible. In ten years of traveling and living in Vanuatu’s remoter regions, this writer has only heard of one yachtie contracting Giardia after drinking local water with permission. However, the water supply issue is becoming increasingly critical as a result of tourism, livestock rearing, fast growing population, and so on. Doctors experienced in treating typical traveler issues may be found at Port-Vila and Luganville. Any more severe issues may need medical evacuation.
While traveling in Vanuatu, be cautious of any minor wounds, scratches, or sores. Small sores, as in most tropical regions, may quickly get infected if appropriate hygiene is not practiced. The majority of these items require common sense. However, the sea water in Vanuatu will not cure your wounds; instead, it will make the condition tragically and quickly worse, requiring IV antibiotics and perhaps amputation. The iodine solution does not function and is said to aggravate the condition. Gentian Violet and Mercuro-Chrome [Cumulative Poison] are superior.
