No vaccinations are required to enter Chile, but it is recommended that travelers are up-to-date on their tetanus and hepatitis jabs. Some cases of Dengue fever have been confirmed in Easter Island; if visiting, you should take steps to avoid being bitten by mosquitos.

Visitors in mountainous regions may suffer from altitude sickness, which produces symptoms of nausea, fatigue, headaches and sleeplessness. If suffering from altitude sickness, it is recommended to stay hydrated, take aspirin or ibuprofen and to avoid alcohol and sleeping pills.

The ozone layer in Chile is thinner than in the US and Europe, especially in the southern region and Patagonia. From September to November, ‘red alert’ days may be declared, where fair-skinned people can burn in as little as 10 minutes. If visiting this region, bring sunscreen, long clothing, a wide-brimmed hat and sunglasses.

Chile is known as one of the safest and most stable countries in South America. However, it is still recommended to be cautious and watch your belongings, especially in Santiago and other large cities, and to avoid flashing valuables or large amounts of money. It is safer to book taxis in advance and to only accept rides from official taxis companies. Keep a photocopy of your passport and other documents to hand in case of emergency.
