Frequently Asked Questions

Do I need health insurance to travel to Costa Rica?

Costa Rica does not currently require proof of health insurance for entry as a standard condition for US citizens visiting as tourists. That said, medical care costs abroad can be significant, and a solid travel health insurance policy protects you if something goes wrong, from a beach injury to an unexpected illness in a remote area. It is one of the smartest things you can pack.

Do you need health insurance to travel to Costa Rica?

There is no universal health insurance entry requirement for US tourists visiting Costa Rica at this time. However, given the range of health considerations in the country, including mosquito-borne illnesses and the coastal rip current risk flagged by the US Department of State, having travel health insurance is a practical decision that gives you real peace of mind throughout your trip.

What are Costa Rica travel health insurance requirements?

As of current guidance from the US Department of State, there is no mandatory travel health insurance requirement imposed on US citizens entering Costa Rica for tourism. Entry requirements focus on a valid passport and a return or onward ticket. Always verify the latest entry conditions with official sources before you fly, as policies can change.

How much is travel health insurance for Costa Rica?

The cost of travel health insurance for Costa Rica varies based on your age, trip length, coverage level, and the insurer you choose. Comprehensive plans that include emergency medical evacuation, trip interruption, and illness coverage tend to cost more but offer the broadest protection in a country where you may be hours from a major hospital. Getting quotes from multiple providers and comparing coverage details is the best approach.

What is the Costa Rica travel health pass?

Costa Rica previously required a health pass for entry during the COVID-19 pandemic, but that requirement has since been lifted. Currently, US citizens entering Costa Rica for tourism need a valid passport and a return or onward ticket, per the US Department of State. Always check current entry requirements directly with Costa Rican immigration authorities or your airline before departure.

How do I complete the Costa Rica health form for travel?

What does the Costa Rica travel health advisory say?

The current Costa Rica travel health advisory from the CDC lists Costa Rica under usual precautions, meaning no heightened alert is in place. Key health considerations include mosquito-borne diseases (with malaria risk concentrated in Alajuela and Limón provinces), the need to be current on routine and destination-specific vaccines, and non-infectious hazards like rip currents on the coast. The advisory recommends standard prevention measures rather than any emergency precautions.

Health Risks in Costa Rica

Costa Rica carries a medium overall health risk level, according to the CDC. The main risks come from mosquito-borne diseases, a specific parasitic condition reported in the country, and a non-infectious but deadly coastal hazard. Knowing where and how these risks show up puts you in control.

Mosquito-Borne Diseases

Costa Rica has a tropical climate overall, with hot and humid lowlands along both coasts and cooler temperatures in the mountainous interior. That climate variation matters for mosquito exposure. Dense rainforest and rural areas increase the time you spend near mosquito habitat, and the risk level shifts depending on which province you visit.

Malaria (a blood infection caused by a parasite and spread through mosquito bites) is present in Costa Rica, but the risk is not nationwide. According to the CDC, transmission occurs in Alajuela and Limón provinces and is rare to absent in other parts of the country. If your itinerary includes those provinces, talk to a licensed travel health provider before you leave about whether preventive medication is appropriate for your specific plans and health history.

Chikungunya (a viral illness spread by mosquito bites that causes fever and severe joint pain) is also a risk for travelers in Costa Rica. According to the CDC, preventing mosquito bites is the primary protection strategy. Use an EPA-registered insect repellent, wear long sleeves and pants during dawn and dusk hours, and sleep in air-conditioned or screened rooms when possible.

New World Screwworm Myiasis

New World screwworm myiasis (an infestation of living tissue by fly larvae, typically entering through a wound or insect bite) has been reported in Costa Rica, according to the CDC. This is an uncommon condition but worth knowing about, especially if you are spending time outdoors, near livestock, or in rural environments. The CDC advises keeping wounds clean and covered, avoiding insect bites, sleeping in screened rooms or under bed nets, and avoiding close contact with livestock. These are simple, practical steps that significantly reduce your exposure.

Coastal Rip Currents

This is not an infectious disease risk, but it is one of the most serious hazards you will face in Costa Rica. According to the US Department of State, rip currents kill dozens of US citizens every year in Costa Rica. Many beaches lack lifeguards, and the currents can be powerful even where the water looks calm. Swim only at beaches with lifeguard coverage, check local conditions before entering the water, and if you get caught in a rip current, swim parallel to the shore rather than fighting it directly.

Terrain and Climate Considerations

Costa Rica's geography compresses a remarkable range of environments into a small country. You can move from sea-level Caribbean coast to highland cloud forest in a matter of hours. The wetter, more humid lowlands and coastal zones carry higher mosquito exposure, while higher-elevation interior areas are cooler and drier. If your trip takes you across multiple zones, your health preparation should account for all of them rather than just the first destination on your itinerary.

Recommended Vaccinations for Costa Rica

Several vaccines are recommended for travel to Costa Rica, and one may be required for entry depending on where you are traveling from. According to the CDC, the list below covers what most travelers should consider before departure.

• Hepatitis A vaccine: Hepatitis A is a liver infection spread through contaminated food or water. According to the CDC, this vaccine is recommended for all unvaccinated travelers aged 1 year and older visiting Costa Rica, and infants aged 6 to 11 months should also be vaccinated before travel (though that dose does not count toward the routine childhood series). Aim to get at least the first dose at least 2 weeks before departure.
• Hepatitis B vaccine: Hepatitis B is a liver infection transmitted through blood or body fluids. According to the CDC, this vaccine is recommended for unvaccinated travelers younger than 60 years old, and unvaccinated travelers aged 60 and older may also choose to get vaccinated. The full series requires multiple doses, so start early if you are not already protected.
• MMR vaccine: MMR protects against measles, mumps, and rubella. According to the CDC, rising measles cases globally mean all international travelers should be fully vaccinated before departure. Confirm you have received two doses before your trip.
• Yellow fever vaccine: Yellow fever is a serious viral illness spread by mosquitoes in certain tropical regions. Costa Rica itself is not a high-risk yellow fever destination, and according to the CDC, the vaccine is not routinely recommended for travel there. However, Costa Rica requires proof of yellow fever vaccination for travelers aged 9 months and older who are arriving from countries with yellow fever transmission risk. If your trip involves a stopover or origin in one of those countries, carry your vaccination certificate.
• Routine vaccines: Make sure you are current on varicella (chickenpox), DTaP or Tdap or Td (diphtheria, tetanus, and pertussis), influenza, polio, and shingles where age-appropriate, according to the CDC. These protect you at home and abroad.
• COVID-19 vaccine: According to the CDC, all eligible travelers should be up to date with their COVID-19 vaccines before international travel.
• Chikungunya vaccine: A vaccine exists but is generally not recommended for most travelers to Costa Rica, according to the CDC. Mosquito-bite prevention remains the primary strategy. If you have specific risk factors, discuss this with a travel health provider.

Your exact vaccine needs depend on your health history, age, and the specific regions of Costa Rica you plan to visit. A travel health provider can review your itinerary and give you a personalized recommendation before you leave.

Tap Water and Food Safety in Costa Rica

Tap water is safe to drink in most urban and tourist areas of Costa Rica, but not everywhere in the country. The answer depends on where you are staying.

Water Safety

In most parts of Costa Rica, including major cities and established tourist destinations, tap water meets safe drinking standards. However, in rural or remote areas, that is not always the case. The practical rule: when you arrive, ask your hotel, host, or property manager directly whether the local tap water is safe. If you get any uncertainty in the answer, or if you are in a rural location, drink bottled water instead. Do not use ice made from tap water in areas where you would not drink the tap water directly. A portable water filter or purification tablets are worth packing if your itinerary takes you off the main tourist circuit.

Food Safety

Costa Rica has a well-developed food scene and most restaurants in tourist areas maintain good hygiene standards. That said, the same common-sense rules that apply anywhere in the tropics apply here. Eat food that is freshly cooked and served hot. Be more cautious with raw salads, unpeeled fruit, and raw shellfish in areas where you are unsure about water quality, since these are often washed or prepared with local water. Street food from busy, high-turnover stalls is generally lower risk than food sitting out in heat. Wash your hands before eating, or use hand sanitizer when soap and water are not available. Hepatitis A (a liver infection spread through contaminated food or water) is a known risk in Costa Rica, which is one reason the CDC recommends the Hepatitis A vaccine for unvaccinated visitors.

Common Traveler Illnesses in Costa Rica

The illnesses most likely to affect travelers in Costa Rica fall into two categories: mosquito-borne infections and bloodborne or food-and-water-transmitted infections. Knowing what to watch for means you can act quickly if symptoms appear.

Malaria

Malaria is a blood infection caused by a parasite and transmitted through the bite of an infected Anopheles mosquito. Symptoms include fever, chills, headache, and muscle aches, typically appearing 7 to 30 days after a bite. According to the CDC, malaria transmission in Costa Rica is concentrated in Alajuela and Limón provinces. If you are visiting those provinces, a licensed travel health provider can assess whether preventive medication is appropriate based on your specific itinerary and health history. If you develop fever during or after travel in those areas, seek medical care promptly and tell the provider where you have been.

Chikungunya

Chikungunya is a viral illness spread by mosquito bites that causes sudden fever and severe joint pain, sometimes alongside a rash. Joint pain can persist for weeks or months after the fever resolves. According to the CDC, chikungunya is a relevant risk for travelers in Costa Rica. There is no specific antiviral treatment, so prevention through mosquito-bite avoidance is key. Rest, fluids, and pain relief medication can help manage symptoms; see a doctor if your fever is high or your symptoms worsen.

Hepatitis A

Hepatitis A is a liver infection caused by a virus and spread through contaminated food, water, or close contact with an infected person. Symptoms include fatigue, nausea, stomach pain, and jaundice (yellowing of the skin or eyes). The illness can sideline you for weeks. According to the CDC, vaccination is the most effective protection. If you have not been vaccinated and you experience these symptoms after eating or drinking something questionable in Costa Rica, see a doctor as soon as possible.

Hepatitis B

Hepatitis B is a liver infection transmitted through blood, sexual contact, or other body fluids. Symptoms can include fatigue, abdominal pain, and jaundice, though some people have no symptoms at all during the acute phase. According to the CDC, vaccination is the primary prevention strategy. If you experience a potential exposure during your trip, such as a medical procedure, tattoo, or injury requiring treatment, seek medical evaluation promptly.

New World Screwworm Myiasis

New World screwworm myiasis is an infestation where fly larvae develop in living tissue, usually entering through a wound, insect bite, or skin abrasion. It has been reported in Costa Rica, according to the CDC. Signs can include a wound that is not healing normally, unusual pain, or visible movement under the skin. This condition requires medical treatment. If you notice any of these signs, particularly after spending time in rural areas or near livestock, seek care from a doctor immediately and describe where you have been.

Visa Requirements for US Citizens Visiting Costa Rica

US citizens do not need a visa to visit Costa Rica for tourism. According to the US Department of State, you can stay for up to 180 days without a visa.

You do need a valid US passport and a return or onward ticket showing you will leave Costa Rica before your permitted stay expires, per both the US Department of State and the official Visit Costa Rica entry requirements. Make sure your passport is valid for the full duration of your trip, and carry your return ticket confirmation when you check in.

One health-related entry requirement applies in specific circumstances: if you are arriving from a country with yellow fever transmission risk, Costa Rica requires proof of yellow fever vaccination for travelers aged 9 months and older, according to the US Department of State. If your itinerary includes a stopover in or travel from a yellow fever risk country, carry your International Certificate of Vaccination (also called a yellow card) to avoid being denied entry.

Entry requirements can change. Always verify current requirements with the official Costa Rica entry requirements page and the US Department of State before you travel.

Quick Answers

I am planning a trip to Costa Rica, what travel health insurance do I need?

Costa Rica does not currently mandate travel health insurance as a condition of entry for US tourists, per the US Department of State. However, given that the country carries a medium health risk level with mosquito-borne diseases in certain provinces and a documented rip current fatality risk on its coasts, a policy that covers emergency medical treatment and evacuation is strongly advisable. Look for a plan that covers hospitalization, medical evacuation, and trip interruption at a minimum.

Can you explain Costa Rica travel health insurance requirements and entry rules?

US citizens entering Costa Rica for tourism need a valid passport and a return or onward ticket, according to the US Department of State and the official Visit Costa Rica entry requirements. There is no general travel health insurance requirement for entry. If you are arriving from a country with yellow fever transmission risk, proof of yellow fever vaccination is required for travelers aged 9 months and older. No visa is needed for stays under 180 days.

I am comparing plans, what is the best travel health insurance for Costa Rica?

The best travel health insurance for Costa Rica is one that covers emergency medical treatment, medical evacuation to a facility capable of handling serious conditions, and trip interruption or cancellation. Costa Rica has good tourism infrastructure in urban areas, but some rural and coastal destinations are far from major hospitals. Given the coastal rip current risk highlighted by the US Department of State and the regional disease risks noted by the CDC, emergency evacuation coverage is particularly worth prioritizing.

How much does travel health insurance for Costa Rica usually cost, and what should it cover?

The cost of travel health insurance for Costa Rica depends on your age, the length of your trip, and the level of coverage you select. Comprehensive plans that include emergency medical care, evacuation, and trip cancellation offer the broadest protection. At a minimum, your plan should cover medical treatment for illness or injury, emergency medical evacuation, and any pre-existing conditions if relevant to your health history. Get quotes from several providers and compare the coverage details, not just the price.

What should I know about the Costa Rica travel health pass and health form before flying?

Costa Rica's pandemic-era health pass and health form requirements have been lifted. US citizens traveling to Costa Rica now need a valid passport and a return or onward ticket, per the US Department of State. The one health document that may still be required is proof of yellow fever vaccination if you are arriving from a country with yellow fever transmission risk. Check the official Visit Costa Rica entry requirements page close to your departure date to confirm no new requirements have been introduced.

Pack Smart for Every Part of Costa Rica

Costa Rica's Caribbean coast, Pacific beaches, and highland rainforest each carry distinct health considerations. The CDC has flagged New World screwworm myiasis as a specific concern for travelers spending time outdoors or near livestock, and routine vaccine status matters more than many travelers realize before departure. A licensed travel health provider can look at your exact itinerary and health history to build a preparation plan that fits where you are actually going, including whether any prescription preventive measures are appropriate for your trip.
