QUICK ANSWER
STATUS: CDC LEVEL 1 — PRACTICE USUAL PRECAUTIONS. The U.S. Centers for Disease Control and Prevention posted a hepatitis A travel notice for Costa Rica on September 18, 2026. CDC says an outbreak is occurring and that most cases have been reported in San José Province.
A Level 1 notice is not a CDC instruction to avoid Costa Rica. It is a prompt to follow the agency's usual precautions and current destination guidance. The notice does not prove that a particular hotel, tour, restaurant, flight, neighborhood or province outside the reported outbreak context is affected.
For trip planning, check the current CDC notice and Costa Rica destination page before departure, review the agency's hepatitis A vaccination guidance, practice careful hand hygiene and food/water precautions, and seek medical care if you become ill or have a specific exposure concern. Personal vaccination or post-exposure decisions belong with a qualified healthcare professional using your medical history and current CDC guidance.
WHAT CDC REPORTED ON SEPTEMBER 18, 2026
CDC's current Level 1 notice says Costa Rica is experiencing an outbreak of hepatitis A and that most cases have been reported in San José Province. Hepatitis A is a contagious liver infection caused by the hepatitis A virus. CDC says it can spread from person to person and through contaminated food or drink.
That geographic wording matters. "Most cases in San José Province" should not be rewritten as "all of Costa Rica is infected," and it should not be converted into an unsupported claim about a specific resort, cruise excursion, restaurant or neighborhood. Travelers should use the official notice for the current outbreak description and check for later updates before departure.
WHAT LEVEL 1 — PRACTICE USUAL PRECAUTIONS — ACTUALLY MEANS
CDC travel-health notices use levels to communicate the type of action travelers should consider. The Costa Rica hepatitis A notice is Level 1, which CDC labels Practice Usual Precautions.
That is different from a destination-wide security advisory and different from a recommendation to cancel travel. It also does not guarantee that a traveler has zero risk. The useful response is to follow the prevention guidance attached to the notice, keep routine travel-health planning current and watch for any later CDC status change.
Do not confuse the hepatitis A notice with every other health issue on Costa Rica's destination page. CDC may publish separate notices for different diseases, places or risk levels. Each notice needs to be read on its own terms.
BEFORE A COSTA RICA TRIP: CHECK THE CURRENT CDC GUIDANCE
CDC recommends hepatitis A vaccination for travelers to Costa Rica under its current destination guidance. Travelers should review the CDC destination page early enough to understand what is recommended for their itinerary and personal circumstances.
Bon Voyage Compass does not determine whether an individual should receive a vaccine, which product is appropriate, or whether a prior vaccination is sufficient. If you are unsure about your vaccination history, pregnancy, immune status, liver disease, medications, allergies, age-specific recommendations or timing before departure, discuss the current CDC guidance with a physician, pharmacist or travel-health clinic.
A booking date is not a medical deadline. If a trip is close, use the current official guidance rather than assuming it is "too late" to ask about prevention options.
HAND HYGIENE AND FOOD / DRINK PRECAUTIONS MATTER
CDC's hepatitis A notice emphasizes vaccination and hand hygiene. The virus can spread when microscopic amounts of stool contaminate hands, food, drink or surfaces, which is why careful handwashing is a practical travel precaution.
Wash hands thoroughly with soap and water after using the bathroom and before eating or preparing food. Follow the current CDC destination guidance for food and water safety rather than relying on a property's marketing claim that an area is "safe." A high-end hotel, tour or restaurant is not a substitute for official health guidance.
Travelers should also avoid turning one outbreak notice into a list of unsupported business accusations. Unless a health authority identifies a particular establishment or event, do not claim that it caused or is linked to the outbreak.
SAN JOSÉ PROVINCE IS THE MAIN REPORTED CONTEXT — NOT A PROPERTY BLACKLIST
CDC says most cases have been reported in San José Province. That makes San José especially relevant when reviewing the notice, but it still does not establish a case at a specific hotel, airport, restaurant or attraction.
If your itinerary includes San José city, Juan Santamaría International Airport connections, nearby communities or a multi-stop route, use the same prevention approach: check the current CDC notice, maintain good hand hygiene and follow current vaccination guidance. Do not infer that merely transiting through the province means a traveler has been exposed.
If a public-health agency later identifies a specific exposure location or changes the notice level, that new evidence should update this same canonical rather than trigger speculative property-by-property pages.
COSTA RICA'S CDC PAGE CAN SHOW OTHER HEALTH NOTICES TOO
CDC's Costa Rica destination page currently also surfaces a separate chikungunya travel-health notice. That is a different disease with different transmission and prevention considerations. The existence of multiple notices does not merge them into one generic "Costa Rica health emergency."
Travelers should open each current notice that applies to their itinerary and date. One notice can be Level 1 while another is a different level or applies to a different geographic area. Use the exact notice title, date and level when making plans.
WHAT THIS MEANS FOR FLIGHTS, HOTELS AND TRAVEL INSURANCE
A CDC Level 1 hepatitis A notice does not by itself prove that an airline has canceled a flight, that a hotel is closed, that a cruise port is unavailable or that a traveler automatically qualifies for a refund.
If the notice changes your plans, check the actual airline, hotel, tour operator and travel-insurance terms that govern your booking. Flexible-change policies and insurance benefits depend on the contract and specific covered reason. Do not assume that a public-health notice automatically activates every cancellation benefit.
Likewise, do not cancel a trip because of a social-media screenshot without checking the live CDC page. Health notices can be updated, and screenshots can omit the notice level, publication date or geographic nuance.
IF YOU FEEL ILL OR THINK YOU HAD A SPECIFIC EXPOSURE
Hepatitis A can cause illness, and CDC provides separate clinical and public-health information about symptoms, testing, treatment and post-exposure management. A travel article cannot diagnose infection or determine whether a particular event counts as an exposure.
If you become ill during or after travel, or believe you had a specific hepatitis A exposure, contact a healthcare professional and tell them about your travel dates and locations. For urgent or severe symptoms, seek appropriate medical care promptly. Use current CDC guidance rather than trying to self-diagnose from a travel checklist.
TRAVELER CHECKLIST FOR COSTA RICA IN LATE 2026
1. Open the live CDC hepatitis A Costa Rica notice and confirm the current level and update date. 2. Review the CDC Costa Rica destination page for vaccination and other current health recommendations. 3. If you are unsure about your hepatitis A vaccination status or personal medical considerations, ask a qualified healthcare professional. 4. Practice careful handwashing with soap and water, especially after bathroom use and before eating. 5. Follow current CDC food and water guidance for the places you will visit. 6. Do not treat "most cases in San José Province" as proof that a specific property or business is linked to the outbreak. 7. If another CDC notice applies to your itinerary, read it separately rather than blending the risks together. 8. Recheck airline, hotel, tour and insurance terms directly if the health notice changes your travel decision. 9. If you become ill or believe you had a specific exposure, seek medical advice and provide your travel history. 10. Recheck the CDC shortly before departure because travel-health notices can change.

LAST VERIFIED
September 22, 2026, using the CDC Level 1 "Hepatitis A in Costa Rica" travel notice and the CDC Costa Rica destination page. The outbreak notice was posted September 18, 2026 and says most reported cases are in San José Province. Recheck CDC before travel because the case geography, notice level and recommendations can change.
Update this same canonical when CDC materially changes the outbreak notice. Do not create city-name copies, resort-name pages or fake-freshness variants unless an authoritative source establishes a genuinely distinct local exposure or travel requirement.
