Hepatitis A
Strongly RecommendedProtects against contaminated food and water — essential for ALL travelers to Brazil, regardless of itinerary. One dose protects your trip; a booster provides lifetime immunity.
Typhoid
Strongly RecommendedBacterial infection spread through contaminated food and water. Especially important if eating street food, visiting local markets, or traveling outside major cities. Available as injection or oral capsules.
Yellow Fever
Strongly RecommendedSTRONGLY recommended for most of Brazil, including the Amazon, Iguazu Falls, and rural areas. Many countries require proof of Yellow Fever vaccination if arriving from Brazil. Single dose provides lifetime protection. Certificate valid 10 days after vaccination.
Hepatitis B
RecommendedSpread through blood and bodily fluids. Recommended for travelers under 60, those who might need medical care abroad, adventure travelers, or anyone staying 6+ months.

Routine Vaccines (Tdap, MMR, Polio)

What to Watch Out For
These are the most common health concerns for travelers to Brazil. Most are preventable with proper precautions.
Dengue Fever
VERY common throughout Brazil, including Rio, Sao Paulo, and all major cities. Brazil reports hundreds of thousands of cases annually. Causes high fever, severe headache, and debilitating joint/muscle pain.
DEET 30%+ repellent, long sleeves, air conditioningZika Virus
Brazil was the epicenter of the 2015-2016 Zika outbreak. Still present throughout the country. Causes serious birth defects — pregnant women should consider postponing travel.
Avoid if pregnant; strict mosquito preventionChikungunya
Mosquito-borne virus causing fever and severe, long-lasting joint pain. Widespread in Brazil, with major outbreaks in recent years.
Mosquito bite prevention 24/7Yellow Fever
Endemic in much of Brazil, including Amazon basin and surrounding states. Can be fatal. Vaccination is the best protection.
Yellow Fever vaccine + mosquito preventionTraveler's Diarrhea
Common, especially outside major tourist areas. Usually from contaminated food or water.
Dukoral vaccine + careful food choicesChagas Disease
Transmitted by triatomine bugs in rural and forested areas, particularly in the Amazon. Can cause serious heart problems if untreated.
Avoid sleeping in mud/thatch structures, use bed netsMalaria Risk in Brazil
Low/Regional RiskGood news: Most popular tourist destinations have NO malaria risk, including Rio de Janeiro, Sao Paulo, coastal cities, and Iguazu Falls. Malaria risk is concentrated in the Amazon basin.
Risk Areas
Risk areas: Amazon basin states (Acre, Amapa, Amazonas, Maranhao, Mato Grosso, Para, Rondonia, Roraima, Tocantins). NO RISK in Rio de Janeiro, Sao Paulo, Brasilia, coastal beaches, or Iguazu Falls.
Recommended Prevention
If visiting the Amazon: Atovaquone-proguanil (Malarone), Doxycycline, or Mefloquine. P. vivax is most common, but P. falciparum also present in some areas. We'll advise based on your specific Amazon itinerary.
Essential Health Tips
Mosquito Protection (Critical)
- Use DEET 30%+ or Picaridin — mosquitoes carry dengue, Zika, chikungunya, AND Yellow Fever
- Apply repellent ALL day, not just at dusk — Aedes mosquitoes bite during daylight
- Sleep in air-conditioned or well-screened rooms
- Wear long sleeves and pants when possible
- Consider permethrin-treated clothing for Amazon trips
Food & Water Safety
- Drink only bottled or purified water
- Tap water in major cities is treated but bottled is safer for travelers
- Be cautious with street food — choose busy vendors with high turnover
- Avoid raw salads and unpeeled fruits from questionable sources
- Fresh fruit juices are delicious but ensure they use purified water
Sun & Heat Safety
- Brazilian sun is intense — use SPF 50+ and reapply often
- Stay hydrated, especially during Carnival or beach days
- Avoid peak sun hours (10am-4pm)
- Wear a hat and quality sunglasses
- Watch for heat exhaustion symptoms
Common Questions About Traveling to Brazil
Yes — Yellow Fever is strongly recommended for most of Brazil and required if you're visiting the Amazon, Iguazu Falls, or rural areas. Even if staying only in Rio or Sao Paulo, many countries require proof of Yellow Fever vaccination if you've been in Brazil. The vaccine provides lifetime protection with a single dose, and you'll receive an International Certificate of Vaccination. Get vaccinated at least 10 days before entering risk areas.
Rio is generally safe health-wise with good medical facilities. The main concerns are mosquito-borne diseases (dengue is very common), sun exposure, and traveler's diarrhea. You don't need malaria pills for Rio. Focus on mosquito protection, stay hydrated, and get your Hepatitis A and Typhoid vaccines. Yellow Fever vaccine is recommended even for Rio as you may travel to other areas and some countries require it.
Amazon travel requires comprehensive preparation: Yellow Fever vaccine (required), Hepatitis A, Typhoid, consider Rabies if having wildlife contact. You WILL need malaria prophylaxis — we'll prescribe Malarone or Doxycycline. Bring strong insect repellent (DEET 30%+), long clothing, and a bed net. The Amazon has serious health risks but with proper preparation, it's an incredible experience.
If you're pregnant or trying to conceive, seriously consider postponing travel to Brazil — it was the epicenter of the Zika outbreak and the virus is still present. Zika causes serious birth defects. For others, Zika usually causes mild symptoms, but you should still use strict mosquito protection because dengue and chikungunya are transmitted by the same mosquitoes and are much more unpleasant.
No — Iguazu Falls (both Brazilian and Argentine sides) is not a malaria risk area. You don't need antimalarials for Iguazu, Rio, Sao Paulo, or coastal beach destinations. Malaria pills are only needed if you're visiting the Amazon basin. However, you should still get Yellow Fever vaccine for Iguazu Falls as it's in a Yellow Fever zone.
Carnival is amazing but demanding on your body! Get Hepatitis A and Typhoid vaccines. Bring strong sunscreen and stay extremely hydrated — you'll be dancing in tropical heat for hours. Use insect repellent as dengue is common in Rio. Pace yourself with alcohol, carry hand sanitizer, and ensure you have travel health insurance. Consider bringing electrolyte packets for rehydration.
