International travel is back in full swing, and Rio Carnival 2025 is expected to welcome approximately 1 million visitors. This world-famous event offers a vibrant mix of joyous celebrations, exuberant dancing, dazzling costumes, and electrifying energy. While you embrace the excitement, it’s essential to take precautions to safeguard your health.

If you’re heading to Rio de Janeiro for Carnival 2025, you’ve come to the right place. This comprehensive guide will help you stay safe and healthy during Rio Carnival by outlining key health risks and recommended vaccinations.

When Is Rio Carnival 2025?

Rio Carnival is scheduled to take place from February 28 to March 8, 2025. Events will be held throughout Rio de Janeiro, drawing massive crowds of both locals and international travelers.

Protect Yourself Against Respiratory Infections: COVID-19 & Flu Vaccines

North America is currently experiencing its worst flu season in 15 years. Being in crowded environments—like Rio Carnival parades and street parties—puts you at increased risk of contracting a respiratory illness.

To stay protected:

• Get your flu shot before traveling to reduce the risk of getting sick.
• Update your COVID-19 booster to cover the latest circulating strains in both the U.S. and Brazil.
• Practice good hygiene by frequently washing your hands and using hand sanitizer in crowded areas.
• Consider wearing a mask in crowded spaces. An N95 type mask offers the highest level of protection.

Pertussis Outbreak in Brazil: Get the Tdap Vaccine

Brazil is currently experiencing a whooping cough (pertussis) outbreak, with over 3,300 cases reported since November 2024. Pertussis is highly contagious and can be severe, especially for young children.

All travelers should ensure their Tdap (Tetanus, Diphtheria, and Pertussis) vaccine is up to date. If it has been three years or more since your last Tdap dose, a booster is recommended before traveling.

Yellow Fever: A Growing Concern in Brazil

Yellow Fever is increasingly prevalent in Brazil, including urban areas like Rio de Janeiro. This mosquito-borne disease can be life-threatening, and there is no specific treatment once infected.

Prevention Tips:

• Get vaccinated: The Yellow Fever vaccine provides lifelong protection and is highly recommended for travelers to Brazil.
• Use mosquito repellent: Wear insect repellent containing DEET or Picaridin.
• Wear protective clothing: Long sleeves and pants help prevent mosquito bites.

Although Brazil has no Yellow Fever entry requirements, the vaccine is strongly advised for all travelers.

Mosquito-Borne Diseases: Dengue, Chikungunya, and Zika Virus

Brazil’s warm tropical climate creates an ideal environment for mosquitoes that transmit Dengue Fever, Chikungunya, and Zika Virus. These serious diseases have no specific treatment, so prevention is key.

Dengue & Chikungunya Prevention:

• High risk during Carnival: February and March mark peak transmission season.
• New Chikungunya vaccine available: Consult a travel health specialist to see if you qualify.
• No practical Dengue vaccine for travelers: The best protection is mosquito bite prevention.

Zika Virus Warning:

• Pregnant women should avoid travel to Brazil due to the risk of congenital Zika syndrome.
• Post-travel precautions:
  • Women: Wait two months before conceiving.
  • Men: Wait three months before attempting conception.

Schedule a Pre-Travel Consultation to Update Your Vaccines

To protect yourself from vaccine-preventable diseases, schedule a pre-travel health consultation. A travel health specialist will ensure you are up to date on routine and recommended travel vaccines, including:

• Hepatitis A (recommended for all travelers to Brazil)
• Hepatitis B (especially important for those with potential exposure risks)
• Typhoid (food and waterborne illness risk in Brazil)

Additional Health and Safety Tips for Rio Carnival

Food and Water Safety:

• Drink only bottled or purified water.
• Avoid raw or undercooked food from street vendors.
• Wash hands frequently or use alcohol-based sanitizer.

Prevent Sexually Transmitted Infections (STIs):

• Use protection if engaging in sexual activity.
• Be aware that alcohol and party atmospheres can increase risk-taking behaviors.

Stay Safe in Crowds:

• Be cautious of petty crime such as pickpocketing and scams.
• Avoid favelas due to security concerns.
• Watch your drinks to avoid potential drugging incidents.
• Remain aware of your surroundings, especially in large crowds.

What Is Yellow Fever?

Similar to other tropical diseases like dengue fever and malaria, yellow fever is transmitted through the bite of an infected mosquito, specifically the Aedes Aegypti species. Yellow fever develops between three and six days after the bite, but many of those infected will show no symptoms at all.

Those that develop a mild form of the illness can have a fever, headache, severe chills, body aches, nausea, vomiting, or overall weakness. If it progresses to a more severe form, the infected person will usually feel better for a few days before getting a more intense fever and jaundice of the skin and eyes (where the name yellow fever comes from), followed by organ failure and finally death.

Where Is Yellow Fever Commonly Found?

Here in the West, yellow fever is virtually unheard of, or at least it has been for the past century or so. Before 1905, the last year that the U.S. had a major outbreak, yellow fever killed tens of thousands of people, mostly around the Gulf Coast. Thanks to mosquito population control measures like draining swamps, spraying pesticides, and then in the 1950s, a vaccine, yellow fever has been all but eradicated in the U.S.

Now, yellow fever is endemic to two regions of the world—Sub-Saharan Africa and the Amazon Basin in South America. If you travel to a country in one of these regions, you may need to get a yellow fever vaccine, as these regions could recommend or even require it.

Do I Need a Yellow Fever Vaccine?

That depends on where you’re traveling. Yellow fever is endemic (present in the area) in many countries in Central and South America and Sub-Saharan Africa. These countries often require you to show proof of yellow fever vaccination, especially if you have recently visited another yellow fever endemic country.

Even if a yellow fever vaccine is not required for entry, you may need one if you are visiting areas of risk. Spending a lot of time outdoors or traveling during the rainy season will increase the risk of yellow fever. Your travel health specialist is the best person to assess your risk and is up to date with the latest country-specific requirements.

The vaccine is not without side effects either; between 10% and 30% of travelers may experience flu-like symptoms after receiving their shot. However, the vaccine provides nearly 100% immunity and also provides you with peace of mind should your travels take you to a higher-risk area.

Frequently Asked Questions About the Yellow Fever Vaccine

Where Can I Get a Yellow Fever Vaccine? Vaccine Locations

Because yellow fever is endemic only in certain places, most travelers don’t need to get vaccinated against it. It’s also a live virus vaccine with special considerations for handling and administration. Most primary care physicians do not have access to the vaccine because only CDC-certified vaccination centers, such as designated travel clinics and county health clinics, administer it.

If you live in Arizona, TravelBug Health in Scottsdale is one of the best places to get a yellow fever vaccine. Our travel medicine specialists will have the most up-to-date information about where yellow fever is present and the level of risk your trip might present.

How Much Does the Yellow Fever Vaccine Cost?

The yellow fever vaccine contains a live, attenuated virus, which initiates a stronger immune response than vaccines containing an inactivated virus, such as seasonal flu shots. For this reason alone, you’ll need a consultation with a qualified travel medicine specialist who will review your medical history and weigh the potential impact of those side effects.

TravelBug Health offers the yellow fever vaccine for $399. We administer the vaccine as part of a comprehensive travel consultation ($125), during which we review your medical history, immunizations and other important information about your itinerary.

Does Insurance Cover the Yellow Fever Vaccine?

As with other vaccines needed for travel, most medical insurance will not pay for the vaccine. Because yellow fever is not endemic to the United States, health officials do not include the vaccine in routine immunization schedules. You will be responsible for the cost of the vaccine and the consultation.

How Long Does the Yellow Fever Vaccine Last?

Before 2016, travel medicine experts recommended a booster dose of the yellow fever vaccine every 10 years to maintain immunity. Researchers analyzed decades of vaccine data, leading health authorities to update the recommendations and international health regulations in July 2016; they now consider a single dose of the vaccine sufficient for lifelong protection. However, an additional booster dose of yellow fever vaccine could still be recommended for certain individuals with special health or immune issues.

How To Prevent Yellow Fever

In addition to the vaccine, it is extremely important to practice insect bite precautions to prevent getting yellow fever and other insect-borne diseases, including malaria which is usually also present in yellow fever endemic areas.

• Wear DEET or Picaridin containing Insect Repellent
• Avoid Outdoor Activities at Dawn and Dusk
• Wear Long Sleeves and Pants
• Treat Your Clothing With Permethrin
• Book Accommodations With Air Conditioning or Bed Nets

Protect Yourself With a Yellow Fever Vaccine from TravelBug Health

The chances of contracting yellow fever are exceedingly low if you aren’t traveling to one of the dozen or so countries where it’s endemic. However, if you are traveling to one of them, the yellow fever vaccine is incredibly effective and provides lifetime immunity against the virus.

Yellow fever is only one of the many diseases that may infect travelers. With the help of a travel medicine specialist, you can minimize the risk of contracting them while exploring the globe. TravelBug Health can provide you with a comprehensive pre-travel health consultation to assist you in understanding these risks and how to mitigate them while you’re abroad.
