Costa Rica
Risk:
Low-Moderate

Health Overview
Dengue fever is the primary health concern in Costa Rica, with increasing case counts in lowland and coastal areas during the May-November rainy season. The country has the best healthcare system in Central America, with CIMA Hospital in San Jose rivaling many US facilities. Traveler's diarrhea risk is lower than most Latin American destinations but still present. The key differentiator for prepared travelers is having adventure sports coverage — zip-line, white-water, and ATV injuries are the most common tourist medical events.
Key Health Risks
Moderate-High
Dengue Fever
Nationwide risk in lowland areas. Significant case increases in recent years. Peak during rainy season May-Nov. DEET and permethrin are essential.
Moderate
Traveler's Diarrhea
Lower risk than much of Latin America but still common. Carry azithromycin. Tap water in San Jose is generally safe; use bottled water elsewhere.
Moderate
Adventure Sport Injuries
Zip-line, white-water rafting, ATV, and surfing injuries are the most common tourist medical events. Verify operator safety records. Ensure insurance covers adventure activities.
Health Risk Callout
Rip currents on Pacific coast beaches are the number one cause of tourist deaths in Costa Rica. Many beaches lack lifeguards.
Other Health Risks
Venomous snakes (fer-de-lance in jungle areas), rip currents (Pacific beaches — leading cause of tourist drowning), sun exposure at tropical latitude, Chagas disease (rare) | 2026 UPDATE: Dengue: 2026 dengue alert reported; ~1,411 accumulated cases early 2026 though incidence sharply reduced vs prior years. (https://denguevisualatlas.com/en/dengue-alert-in-costa-rica-with-1411-accumulated-cases-in-2026/, 2026) ; Hantavirus: Local reporting flagged hantavirus awareness for travelers alongside dengue (rural rodent exposure).

Regional Information
Regional Risk Callout
Risk is relatively uniform across the country. San Jose has the best medical infrastructure. Caribbean coast (Limon province) has slightly higher dengue and crime risk. Pacific coast tourist areas (Guanacaste, Manuel Antonio) have good clinic access. Remote Osa Peninsula and Corcovado require evacuation planning for serious injuries.
Regional Healthcare Callout
Tourist areas have basic clinics (clinicas) that handle minor issues. Serious injuries or illness require transfer to San Jose. Osa Peninsula and remote Caribbean areas may need air evacuation.
Vaccine and Malaria Prevention
💉 Entry Vaccine Required
None required for entry.
🛡️ Recommended Vaccines
Hepatitis A, Typhoid, Hepatitis B, Rabies (adventure/rural), Routine (Tdap, MMR, Flu, COVID-19)
🦟 Malaria Information

- Areas: Rare focal transmission in Limon province lowlands. Not in Central Valley, Pacific coast, or tourist areas.

Moderate
Physician Note

Emergency Medicine · 25+ Years · 40+ Countries
Costa Rica is one of the safest and most medically accessible countries in Latin America, and I recommend it as a great first international destination for families. CIMA Hospital in San Jose has a Baylor affiliation. The health risks are real but manageable — dengue is increasing and DEET discipline matters, but the biggest actual threat is adventure sport injuries.
Zip-line operators vary wildly in safety standards. Check reviews, check equipment, and make sure your insurance explicitly covers adventure activities — many basic travel policies exclude them.

Notes
Special Evacuation Notes
Air ambulance to Miami is approximately 3 hours. Good in-country air ambulance services available.
Safety Notes
Petty theft and car break-ins are the main crime concern, especially in San Jose and at trailheads. Volcanic activity (Arenal, Poas, Turrialba) can close areas without warning. Earthquake-prone. Rainy season flooding can isolate roads.
