Travel Vaccines and Advice for Ecuador

• Typhoid – Typhoid, a bacterial infection, is primarily transmitted through contaminated food, water, or direct contact with infected people. Vaccination is a key preventive measure, recommended for travelers to endemic regions and those at risk due to occupation.
• Hepatitis A – Be sure to protect yourself from hepatitis A, a contagious liver infection caused by HAV, through vaccination. The virus spreads through contaminated food, water, and close contact. Along with vaccination, maintaining proper hygiene and avoiding undercooked shellfish are essential for prevention.
• Yellow Fever – Yellow fever, a viral disease transmitted by infected mosquitoes, causes a range of symptoms, including jaundice and bleeding. Preventing it is crucial. The yellow fever vaccine is administered at least 10 days before travel to endemic areas, providing long-lasting immunity and playing a vital role in controlling the virus’s spread.
• Rabies – The rabies virus is a deadly threat that spreads through bites and scratches from infected animals. Preventing rabies involves timely vaccination, avoiding contact with wildlife and seeking immediate medical attention if bitten. The rabies vaccine is instrumental in developing immunity and safeguarding against this fatal disease.
• Hepatitis B – Hepatitis B prevention relies on vaccination as the most effective measure, recommended for all travelers and critical for healthcare workers. Practicing safe sex and using sterile equipment for body modifications are also key in reducing transmission risks.
• Measles, Mumps, Rubella (MMR) – Measles, mumps, and rubella are highly infectious diseases that can lead to complications like pneumonia and encephalitis. To combat these threats, vaccination with the MMR vaccine is imperative. This two-dose vaccine not only shields individuals but also contributes to herd immunity, reducing the risk of outbreaks.

Yellow fever vaccination is recommended for travelers to regions in Ecuador that are under 7,500 feet elevation. Travelers are advised to receive the vaccine at least 10 days before arrival in the country. As yellow fever is common in Ecuador, proof of vaccination may be required when entering another country.

In Ecuador, malaria is most common in regions under 5,000 feet elevation, especially in the provinces of Carchi, Cotopaxi, Esmeraldas, Morona-Santiago, Orellana, Pastaza and Sucumbios. Rare cases occur in other provinces. Travelers are advised to take antimalarials to protect themselves from infection. Atovaquone, doxycycline, mefloquine and tafenoquine are recommended for travelers to the region. Malaria parasites in Ecuador are resistant to chloroquine. Speak with your travel health specialist to identify which antimalarial is best for your trip and medical history.

Mosquitoes and other biting insects spread several diseases in Ecuador, most of them have no vaccine. Preventing bites is your best line of defense for your trip.

Bug bite prevention comes down to a few consistent habits:

• Cover exposed skin with long sleeves, long pants and a hat.
• Use a repellent with DEET, picaridin, oil of lemon eucalyptus or IR3535 and reapply it as directed.
• Treat clothing, boots and gear with permethrin, keep it off your skin.
• Sleep in a screened or air-conditioned room, or under a bed net if your stay is more open-air.

None of this is complicated. It just has to be consistent.

Travelers’ diarrhea, hepatitis A and typhoid are the most common food- and water-related risks for visitors to Ecuador. It all comes down to what you eat and drink.

Tap water in Ecuador isn’t reliably safe, even in cities. Stick to bottled or sealed water and check the seal before you buy it. Skip ice unless you know it was made from purified water. Use bottled water to brush your teeth. A portable filter or purification tablets are worth packing if you’re headed somewhere rural.

Food safety follows a similar logic. Choose meals that are freshly cooked and served hot, and be cautious with anything that’s been sitting out. Peel fruit yourself instead of eating pre-cut pieces, and be selective with street food. Busy stalls with high turnover are generally a safer bet than food that’s been sitting around. Unpasteurized dairy is common in rural areas and worth avoiding.

Hepatitis A and typhoid vaccines cover two of the biggest risks here, and a Passport Health specialist can tell you which one fits your trip.

Altitude sickness, or acute mountain sickness (AMS), occurs when oxygen levels decrease at high elevations, leading to symptoms like headaches and nausea. Prevent AMS by ascending slowly, staying hydrated, and considering medications like acetazolamide. If symptoms persist or worsen, descend to lower altitudes and seek medical attention if needed.

• Chagas disease – Spread when the feces of an infected bug get rubbed into a bite, cut, or the eyes, though it can also pass from mother to child or through contaminated blood or food. Rural Ecuador’s older adobe and thatch housing gives the bugs more places to hide. Sleeping under a bed net in rustic accommodations lowers your risk.
• Dengue – A mosquito-borne virus spread through the bite of an infected Aedes mosquito, which feeds during the day rather than at dusk or dawn. Ecuador sees year-round dengue activity, particularly in coastal and lowland areas. Apply repellent throughout daylight hours, not just in the evening.
• Hantavirus – Spread by breathing in dust contaminated with the urine, droppings, or saliva of infected rodents, or less commonly through a rodent bite. Rural and agricultural parts of Ecuador carry the highest risk.
• Leishmaniasis – Spread by the bite of an infected sand fly, most active between dusk and dawn in Ecuador’s forested and rural regions, including the Amazon basin. Standard mosquito nets don’t always block sand flies because of their smaller size. Look for fine-mesh netting when staying in an affected area.
• Leptospirosis – Bacteria spread through contact with fresh water, mud, or soil contaminated by infected animal urine, most often after flooding or heavy rain. Travelers doing agricultural work or freshwater activities in Ecuador face the highest risk. Avoid wading through floodwater or streams if you have open cuts or scrapes.
• Melioidosis – A bacterial infection picked up through contact with contaminated soil or fresh water. Ecuador’s rainy season raises exposure in muddy or flooded areas. Keep open cuts covered and out of standing water after storms.
• New World screwworm – Caused by fly larvae that hatch from eggs a fly lays in an open wound or in the nose and mouth. Clean and cover any cuts or scrapes promptly, and avoid leaving wounds exposed outdoors.
• Tuberculosis (TB) – Spread through the air when someone with active TB coughs, speaks, or sings nearby. Risk rises with extended stays, work in healthcare settings, or time spent in crowded, poorly ventilated spaces in Ecuador. Long-stay travelers in these settings should consider TB testing before and after the trip.
• Zika – Spread mainly through the bite of an infected mosquito. It can also pass from a pregnant traveler to their unborn baby. Standard mosquito bite precautions apply throughout your trip. Travelers who are pregnant or trying to conceive should talk to a doctor about their risk before booking travel.
