Ecuador Health

No vaccinations are required for entering to Ecuador. However, a yellow fever vaccination is for all Amazon trips, including Orellana, Sucumbios, Sacha, La Selva, Napo, and Kapawi. The vaccination does not apply for visitors going to the Galapagos Islands, the highlands or the coast. This certificate will NOT be requested at Quito or Guayaquil airports upon international arrival.

Here are some health recommendations:

Because of high altitudes in certain areas of Ecuador, such as Quito, travelers with particular heart conditions or high blood pressure should consult their doctors.
Make sure your food and drinking water are safe. Do not eat food purchased from street vendors or food that is not well cooked to reduce risk of infection.
Dengue is a disease carried by insects that occurs in tropical areas of Ecuador during the rainy season. No vaccine is available. Travelers should be advised that they can reduce their risk of acquiring dengue by remaining in well-screened or air-conditioned areas when possible, wearing clothing that adequately covers the arms and legs, and applying insect repellent to both skin and clothing.
As the sun at the equatorial latitude is quite strong, we suggest you use sunscreen at all times. Make sure that you protect your head, face, arms, and legs while you are on the sun deck or during the visit on land.
In addition, some people will experience the effects of sea motion. Talk to your doctor about prevention of seasickness.

Seasickness

Excessive stimulation to the inner ear, caused by the repetitive swaying and motions of the sea, can cause seasickness, a form of motion sickness characterized by a feeling of nausea and, in extreme cases, vertigo experienced after spending time on a craft on water. It is typically brought on by the rocking motion of the boat, but people who are particularly vulnerable to the condition can feel seasick simply by setting foot on a boat, even if the vessel is in dry dock.

Here are some recommendations for keeping seasickness at bay:

Talk to your doctor about prescription medicines, or consider over-the-counter medication.
Drink plenty of water before your trip. Good hydration helps prevent seasickness. However, once on board, avoid foods and fluids until you are sure you won't get seasick. Avoid all alcoholic beverages; alcohol can not only add to your tipsy feeling but also promote dehydration.
Avoid fatty and spicy food.
Position yourself where the least motion is felt, usually in the center of the deck, and avoid going below deck.
Take deep breaths and stare out into the distance. Focus on the horizon, not on waves or moving objects.
Don't read or watch television.
Don't face backwards. This aggravates the feeling of visual disorientation.
Occupy your mind focusing on something other than being seasick.
