QUICK ANSWER
Costa Rica has an active chikungunya outbreak that travelers should verify before departure. The Costa Rican Ministry of Health reported on September 17, 2026 that local transmission had been confirmed in several sectors of Pavas, a district of San José, and that vector-control work had been intensified. CDC’s current Costa Rica Traveler View lists “Chikungunya in Costa Rica” under Level 2 — Practice Enhanced Precautions and tells travelers to prevent mosquito bites.
This is a health-planning alert, not a statement that all of Costa Rica has the same risk. Conditions and affected areas can change. Use the current CDC Costa Rica Traveler View and Costa Rica Ministry of Health updates before and during the trip, especially if your itinerary includes San José or Pavas.
WHAT COSTA RICA REPORTED IN PAVAS
On September 17, Costa Rica’s Ministry of Health said it had detected a chikungunya outbreak in different sectors of Pavas and confirmed local transmission. The Ministry named Villa Esperanza, Finca San Juan, Laureles, Pavas Centro and Rohrmoser among the sectors associated with the outbreak.
At that update, the Ministry reported 22 people who had laboratory testing connected with the outbreak: 12 confirmed cases, three probable cases, three pending results and four discarded results. The first identified cases had travel history to Nicaragua, but the Ministry said local transmission was now confirmed.
Those counts are a dated snapshot, not a permanent total. Do not reuse them as if they describe the situation weeks later. Recheck the responsible health authorities for current numbers and geography.
WHAT CDC CURRENTLY SHOWS FOR COSTA RICA
CDC’s Costa Rica Traveler View currently lists chikungunya under Level 2 — Practice Enhanced Precautions. The page says there is an outbreak of chikungunya in Costa Rica and advises travelers to protect themselves from mosquito bites. The same destination page separately lists other current travel-health notices, which is why travelers should review the full Costa Rica page rather than relying on one disease headline.
A CDC travel-health notice is not the same thing as a State Department security advisory, an airline cancellation, a border closure or a legal prohibition on travel. Treat each source according to what it actually covers.
MOSQUITO-BITE PREVENTION IS THE PRACTICAL CORE
Costa Rica’s Ministry of Health recommends mosquito-bite and breeding-site precautions. Its Pavas outbreak update tells people to use registered repellent, use mosquito nets where appropriate, eliminate containers and objects that collect standing water, keep stored-water containers covered and regularly inspect places where water can accumulate.
For a traveler, that means packing effective insect repellent, planning clothing and lodging with mosquito exposure in mind, and continuing precautions during daytime and evening activities rather than assuming a hotel zone or urban itinerary eliminates risk.
SYMPTOMS AND WHEN TO SEEK CARE
Costa Rica’s Ministry of Health says symptoms can include high fever, joint pain and inflammation, headache, nausea and general malaise. CDC also describes fever and joint pain as common symptoms and notes that some people can have prolonged joint pain.
If symptoms develop during or after travel, seek appropriate medical evaluation and tell the healthcare professional about the Costa Rica itinerary and possible mosquito exposure. This guide does not diagnose illness or replace individualized medical advice.
IF YOUR ITINERARY INCLUDES SAN JOSÉ OR PAVAS
Do not assume San José is one uniform exposure area. Check the exact neighborhoods, lodging location and daily activities. Pavas contains residential, commercial and airport-adjacent areas, and the Ministry’s September 17 update named specific sectors associated with the outbreak.
Before a stay in or near Pavas, recheck the Costa Rica Ministry of Health for newer outbreak updates and the CDC destination page. If an accommodation or tour operator makes a health or closure claim, compare it with the official sources rather than treating a sales message, social post or old screenshot as definitive.
DO NOT TURN A HEALTH ALERT INTO A FAKE CANCELLATION CLAIM
An outbreak notice does not prove that a particular hotel, tour, airport, airline, cruise call or attraction is closed. Verify transportation and property operations directly with the responsible provider. Bon Voyage Compass will not fabricate cancellations, fares, inventory, border rules or operator restrictions from a public-health notice.
For nonrefundable travel, read the actual carrier, lodging and insurance terms before changing plans. Health notices and travel advisories may affect personal risk decisions without automatically creating a refund right.
2027 PLANNING: RECHECK RATHER THAN CARRYING 2026 STATUS FORWARD
Travelers planning Costa Rica for 2027 should not assume this September 2026 outbreak geography, case count or CDC notice level will remain unchanged. Use this page as a watch point, then recheck CDC and Costa Rica’s Ministry of Health close to booking and again before departure.
This canonical should be refreshed when the responsible agencies materially change the outbreak status, geography or traveler guidance. It should not be copied into thin San José, Pavas, resort, airport or date variants.
