General Information

Costa Rica is a developing nation classified as upper middle income.

Yellow Fever

See also: Library article for Yellow Fever

Although yellow fever does not occur in Costa Rica, an official yellow fever vaccination certificate may be required depending on your itinerary.

  • Requirement:

    A certificate proving yellow fever vaccination is required for travelers aged ≥ 9 months coming from countries with risk of YF transmission (except Argentina and Panama), from Tanzania and Zambia, and with specifications for the following risk countries: Colombia (the entire country except the capital city of Bogotá and Barranquilla, Cali, Cartagena, Medellín, and San Andrés Providencia); Ecuador (applies only to Morona-Santiago, Napo, Orellana, Pastaza, Sucumbíos, and Zamora-Chinchipe and excludes the rest of the country); Paraguay (the entire country except the capital city of Asunción); Perú (the entire country except the capital city of Lima, Cajamarca, Cuzco, Lambayeque, Piura, Tumbes, Inca Trail, and Machu Picchu); Trinidad and Tobago (the entire country except the urban areas of the capital city of Port of Spain, the island of Tobago, and travelers in transit). Note: This does not apply to airport transit stops (no exit through immigration checkpoint) in risk countries.

    Supplementary requirement for exit: Costa Rican authorities enforce proof of YF vaccination for residents departing Costa Rica for a country with risk of YF transmission and who intend to return to Costa Rica. This exit requirement is to supplement Costa Rica's existing entry requirement under the International Health Regulations.

Other Vaccines

Depending on your itinerary, your personal risk factors, and the length of your visit, your health care provider may offer you vaccination against COVID-19, hepatitis A, hepatitis B, influenza, measles, mumps, rubella, rabies, or typhoid fever. Routine immunizations, such as those that prevent tetanus/diphtheria or "childhood" diseases, should be reviewed and updated as needed.

The following is current information as reported by the World Health Organization (WHO) and the US Centers for Disease Control (CDC):

WHO—International Travel and Health (current online update, Country List)

(2020) Very low Malaria risk was historically due almost exclusively to P. vivax. Negligible or no risk of malaria transmission exists in the country.
  • Recommended prevention in risk areas: A - Very limited risk of malaria transmission. Mosquito bite prevention only.

WHO Country List footnote: When available, the date of the most recent update or confirmation is indicated in parentheses in the country list. If no date is indicated, the most recent update or confirmation was provided before 2013.

Other Concerns

Travelers' Diarrhea

See also: Library article for Travelers' Diarrhea

High risk exists throughout the country, with moderate risk in deluxe accommodations. Community sanitation and food safety measures are generally inadequate. Some itineraries (e.g., remote destinations, austere accommodations) and activities (e.g., ecotourism, eating street or local-market food) further increase risk.

Travelers should observe food and beverage precautions, which reduce the likelihood of illness.

Travelers should carry loperamide for self-treatment of diarrhea and, if risk is moderate to high, an antibiotic to add if diarrhea is severe. Consult a knowledgeable health care provider regarding which antibiotic is appropriate for you and most effective for your destination.

Other Food-Borne Illnesses

Precautions to prevent brucellosis, seafood poisoning may be needed.

Insect- and Arthropod-Borne Diseases

Chagas' disease (American trypanosomiasis), chikungunya, dengue, leishmaniasis, Rocky Mountain spotted fever, West Nile virus, Zika may pose a risk. Personal protective measures are important.

Other Disease and Health Risks

Additional concerns include air pollution, anthrax disease, helminths, leptospirosis, marine hazards, melioidosis, sexually transmitted infections, snakebites.

Consular Advice

The material below includes information from the US Department of State (DOS), the UK Foreign, Commonwealth & Development Office (FCO), Global Affairs Canada (GAC), and Australia's Department of Foreign Affairs and Trade (DFAT), as well as from additional open-source material. Standard safety precautions that apply to all international travel can be found in the Library article Safety and Security.

Terrorism Risk

No intrinsic risk of attack by terrorist groups exists, but unforeseen attacks are possible.


High risk of violent crime (armed robbery, home invasion, sexual assault, carjacking, and murder) exists throughout the country, especially in coastal areas of Limón Province (from Tortuguero to Puerto Viejo de Talamanca) and Puntarenas Province; on main highways in Central Valley region; in San José. Theft of valuables from unattended rental vehicles is common.

High risk of petty crime exists throughout the country, especially in areas frequented by tourists, including San José (particularly the Coca Cola bus terminal, public parks, and downtown), national parks, and beaches; the following areas along the Caribbean: Cahuita, Limón, and Puerto Viejo de Talamanca; the following areas of Puntarenas Province: Dominical, Jacó, Manuel Antonio National Park, Quepos; Cobano area (including Mal País, Montezuma, and Santa Teresa), the port of Puntarenas, and areas near the popular crocodile viewing area along the Tárcoles River near Jacó.

Express kidnappings to force cash withdrawals at ATMs may occur throughout the country.

Risk exists of robberies and/or assaults occurring after consuming intentionally drugged food or drink; tourists are frequently targeted.

Civil Unrest

Protests and demonstrations occur throughout the country, especially in San José, and are generally peaceful but have the potential to turn violent without warning. Bystanders are at risk of harm from violence or from the response by authorities. Disruption to transportation, free movement, or the ability to carry out daily activities may occur.

Water Safety

Hazardous water conditions (including currents, tides, and undertows) may occur along the Pacific and Caribbean coasts. Heed posted warnings, and avoid beaches that are not patrolled. Do not swim alone or after dark, and do not walk on any beach after dark.

Passenger boats may be unsafe, including small crafts. Decline water transportation in vessels that appear overloaded or lack personal flotation devices or life jackets.

Basic safety standards for recreational water activities (including scuba diving and rafting) are often not in place. Rent water sports equipment from reputable operators. Scuba dive only with personnel certified by PADI or NAUI, and use equipment only from PADI- or NAUI-certified dive operators.

Outdoor Safety

Basic safety standards for adventure activities (including bungee jumping and canopy tours) are often not in place. Travelers should only use reputable adventure-sport operators for activities and equipment rentals.

Other Safety Threats

Risk exists for fatal wildlife attacks from crocodiles in coastal areas of the Pacific Ocean, especially in Playa Azul, Guanacaste Province and Playa Esterillos, Puntarenas Province. Travelers should closely follow regulations from local authorities and always maintain a safe distance from wildlife.

Transportation Safety

High risk of traffic-related injury or death exists. The road traffic death rate is 12 to 24 per 100,000 population. The rate is less than 10 in most high-income countries.

Speed laws are poorly enforced.

Seat belt laws are poorly enforced.

Drunk driving laws are poorly enforced.

Structural standards for vehicles may not meet international standards.

Airline Safety

The US Federal Aviation Administration has determined that the civil aviation authority of this country oversees its air carriers in accordance with minimum international safety standards.
