HEALTH IN ECUADOR

The geography and climate of Ecuador, in some cases may influence your health, specially on high altitudes such as Quito. You should also be precautious in tropical areas since insects that can transmit diseases can be found. Also be careful on what you eat and where you eat it.

Weather and Altitude Sickness

Ecuador's weather is characterized for being very variable. In some places you can experience, in a single day, strong changes in temperature. This is very common in the Andean region. High factor sunscreen, sunglasses and also warm clothes are recommended. In the Andean region you should be also cautious of altitude sickness. Ecuador is home to some of the highest volcanoes and mountain peaks in the world. Someone flying from New York City to Quito, for example, experiences an elevation change of nearly two miles in a little more than 6 hours. Abrupt changes in elevation such as this sometimes have ill effects on travelers. Altitude sickness usually manifests itself in insomnia, headaches, and/or nausea. To prevent altitude sickness, or to at least avoid its effects, ascend gradually to provide your body time to adjust to the change. Obviously, if you are flying into Quito this will be impossible. The first thing you have to do is to avoid extreme physical efforts for the first two or three days. (Ex: running, lifting heavy objects, practicing sports) In the event that you do experience symptoms of altitude sickness, in most cases, they can be remedied by drinking lots of water, getting lots of rest, and taking aspirin.

Insects

No vaccine is required to enter Ecuador, but is good to know that in certain areas of the country, (tropical areas) live insects that may transmit malaria and yellow fever.

Medical Care

Good medical care is available in Quito and Guayaquil. There is lack of hospital infrastructure in small towns.
Some embassies have lists of excellent multi-lingual doctors.
