Altitude is what will actually affect you, in Quito on the first day. Private clinics in the cities are good and cheap; the Galapagos and the Amazon are a flight from anywhere.

  • Quito is at 2,850 metres and it is the highest many visitors have ever slept. Headache, breathlessness and poor sleep on the first day or two are normal.
  • Confusion, vomiting or breathlessness at rest are not normal. That is altitude sickness proper and the treatment is to go down, immediately.
  • The TelefériQo at 4,050 metres, Cotopaxi and Quilotoa are far higher again, and are day trips people take on day two and regret.
  • Dengue and zika are daytime-biting, so use repellent through the day in the lowlands; there is no malaria above about 1,500 metres and none in the Galapagos.
  • You are on the equator and at altitude, so burning takes 15 minutes in the sierra on a cool cloudy day. High-factor sunscreen, sunglasses and a hat are not optional.

Altitude, which is the health issue here

Quito is at 2,850 metres and it is the highest many visitors have ever slept. Almost everyone feels it.

  • Headache, breathlessness, poor sleep, no appetite and a racing pulse are all normal on the first day or two.
  • Do nothing on the day you arrive. No hiking, no drinking, no big meal.
  • Drink far more water than usual, and coca tea if it is offered.
  • Cotopaxi, Quilotoa and the Quito TelefériQo at 4,050 metres are considerably higher again, and are day trips people take on day two and regret.
  • Confusion, vomiting or breathlessness at rest are not normal. That is altitude sickness proper, and the treatment is to go down, immediately.
  • Ask a doctor about acetazolamide before you travel if you are heading straight to high altitude.

Vaccinations and mosquitoes

  • Yellow fever vaccination is recommended for the Amazon provinces, and a certificate may be asked for if you travel on to another country afterwards.
  • Hepatitis A and typhoid are routine recommendations, and rabies is worth discussing for remote travel.
  • Dengue, zika and chikungunya are present in the coastal and Amazon lowlands and are daytime-biting mosquitoes, so repellent through the day rather than just at dusk.
  • Malaria risk exists in parts of the lowlands and none at all above about 1,500 metres, which means Quito, Cuenca and the sierra are clear.
  • There is no malaria and no yellow fever in the Galapagos.

Medical care

  • Private clinics in Quito, Guayaquil and Cuenca are good and inexpensive by North American or European standards, and are where you should go.
  • Hospital Metropolitano and Hospital de los Valles in Quito, and Clinica Kennedy in Guayaquil, are the ones foreigners are usually directed to.
  • Public hospitals are free at the point of emergency and are overstretched.
  • You pay up front and claim afterwards. Keep itemised receipts.
  • The Galapagos and the Amazon have basic facilities only. Anything serious means a flight to the mainland, which is why insurance with evacuation cover matters more here than the mainland cost of treatment suggests.

Food and water

  • Do not drink the tap water. Bottled or properly filtered.
  • Ice and salads in established restaurants in the cities are generally fine, and at a roadside stall are not.
  • Stomach upsets are common in the first days, usually from the change rather than contamination. Carry rehydration salts.
  • The street food is excellent and the busy stall with a queue of locals is the safe one.
  • Seafood on the coast is superb, and ceviche is safe where the turnover is fast.

The sun

  • You are on the equator and at altitude. The ultraviolet index in Quito is among the highest measured anywhere on earth.
  • Burning takes 15 minutes in the sierra, on a cool cloudy day, in the shade of a hat brim.
  • High-factor sunscreen every day, sunglasses, and a hat. This is not optional at 2,850 metres.
