Entry & Exit Requirements
Note: Most Antarctica trips depart from Argentina.
U.S. citizens must have a valid passport to enter Argentina. Passports must be valid for at least the duration of your stay. As this requirement is subject to change at any time without notice, we recommend at least 6 months' validity.
A visa is not required for visits up to 90 days.
If you are not traveling with a U.S. passport, please check with the Argentine Embassy for the requirements based on your nationality.
Health Information
Immunizations
The Centers for Disease Control recommends that all travelers be up to date on routine vaccinations such as measles-mumps-rubella (MMR) vaccine, diphtheria-pertussis-tetanus vaccine, varicella (chicken pox) vaccine, and your yearly flu shot before every trip.
There are no vaccinations required for entry into Antarctica or Argentina.
The CDC recommends that most travelers get hepatitis A, hepatitis B, and typhoid vaccines before visiting Argentina.
If you are extending your time in Argentina, please note that yellow fever is a risk in the Corrientes and Misiones provinces (including at Iguazú Falls). The CDC recommends the yellow fever vaccine if you are traveling to these areas.
Please consult your physician for additional information and recommendations based on your individual circumstances.
Dengue Fever & Other Insect-borne Illnesses
Locally transmitted cases of dengue fever have been reported in Argentina. Local transmission means that mosquitoes in the area have been infected with dengue and are spreading it to people. In addition, locally transmitted cases of leishmaniasis, Zika virus, and other insect-borne illnesses have previously been reported in Argentina.
To protect against insect bites, cover exposed skin with lightweight, long-sleeved shirts and pants, and use an insect repellent containing an active ingredient like DEET or picaridin. If visiting tropical, lowland sites, consider treating clothes with permethrin.
The CDC recommends that travelers to Argentina protect themselves against mosquito bites. As a precaution, the CDC advises women who are pregnant to consider postponing travel to any area where Zika virus transmission is ongoing.
Severe Weather
Antarctica is the coldest, windiest, and driest place on earth. Temperature patterns vary widely because the continent is covered in continuous darkness during the winter and continuous sunlight during the summer, with a few weeks of sunrises and sunsets between seasons. For travelers to Antarctica, severe low temperatures and high winds are the primary health hazards.
Frostbite
Frostbite is damage to the skin from freezing and is due to prolonged exposure to cold temperatures. Symptoms include patches of reddened skin that become white, hard, and swollen; or skin that burns, tingles, or is numb or painful. Severe cases can result in blisters or ulcers forming and may involve deeper tissues. The most common sites for frostbite are the fingers, hands, toes, feet, ears, nose, and cheeks. To avoid frostbite, dress warmly and in layers but avoid tight clothing as it may reduce circulation. Keep the face and extremities covered. Avoid overheating and excessive perspiration. Change out wet clothing, especially socks and gloves.
Hypothermia
Hypothermia is life threatening. It is caused by cold, wet, or windy weather that causes the body to lose heat faster than it can produce heat. Symptoms include feeling cold, uncontrollable shivering, clumsiness due to loss of muscle coordination, slurred speech, inability to think clearly, and eventual unconsciousness and cessation of reflexes including heart and lung functions. Many victims in the later stages of hypothermia feel warm and try to shed clothing. To treat hypothermia, first warm the core of the body before the extremities. Remove any wet clothing. Re-warm the victim slowly; do not warm fast by immersing in warm/hot water. Provide shelter out of the weather. Warm drinks are not necessary, but may help in the psychological recovery. Do NOT give alcohol. Try to keep victim awake as this helps keep the body temperature up.
Sun Exposure
Despite freezing temperatures, the effects of the sun in Antarctica (because of the sun’s reflecting off the snow) can be damaging to the eyes and skin. Spending time outdoors exposes you to the sun’s harmful ultraviolet (UV) rays, even on cloudy days. To protect yourself from the sun, use a broad spectrum sunscreen of at least SPF 15, protect skin with clothing, wear a wide-brimmed hat and sunglasses, and drink plenty of fluids.
Currency
Antarctica does not have an official currency. The currency of Argentina is the Argentine peso.
