The health and medical situation in Honduras varies drastically in quality and in availability throughout the country. Outside of the major city of San Pedro Sula and the capital, Tegucigalpa, the only medical services available throughout the country are insufficient and cannot accommodate patients for complex situations. The support staff and the facilities they work in are not up to U.S standards anywhere in Honduras. Modern facilities for advanced surgical procedures are not available anywhere in the country. Even general surgery hospitals are very rare and not even found in the popular tourist areas of the Bay Islands. Ambulance service is limited to only a few major cities and found nowhere else.
Hondurans are regularly exposed to drinking water that is heavily contaminated with parasites and other viruses. The most common complaint and medical concern of the locals are about the parasites that infest their stomachs due to the contaminated water supply.
Some of the ongoing medical problems in Honduras are caused by mosquito-borne illnesses. Even if you are just traveling for a few days through the country, it is very possible for you to contract malaria.
Severe air pollution in Honduras during the dry season is common. This is mostly because of widespread fires throughout the mountains and the regular burning of trash and agricultural waste. Many of the people who live out in the mountains have no easy means of getting their trash out of the villages they live in. Most villages have large, centrally located trash mounds where they regularly burn off their waste and then bury it or let the rain wash it away. Some also just burn their trash privately near to where they live.
