## Executive GIST (TL;DR)
- The CDC has issued a Level 1 travel notice for **hepatitis A** in Costa Rica, indicating travelers should "Practice Usual Precautions." Most reported cases are from San José province. - **Hepatitis A virus (HAV)** is a vaccine-preventable liver infection transmitted when a person ingests the virus, commonly via close person-to-person contact or contaminated food or drink. - Symptoms can include dark urine, clay-colored stools, diarrhea, fatigue, fever, joint pain, loss of appetite, nausea, abdominal pain, and jaundice; some children may be asymptomatic. - Incubation typically begins 2–4 weeks after exposure (range 15–50 days); symptoms usually resolve within 2 months but can last up to 6 months in some people. - Higher risk for severe disease: older adults (over 60), people with chronic liver disease, and those with weakened immune systems. - Prevention recommendations: ensure **hepatitis A vaccination**; if vaccination is not possible, clinicians may recommend **immune globulin** for protection up to 2 months; practice good hand hygiene; avoid sharing needles and practice safer sex. - If exposed and not previously vaccinated, discuss **post-exposure prophylaxis (PEP)** with a clinician; PEP is most effective if given as soon as possible within 2 weeks of exposure. - There is no specific antiviral treatment for HAV; most people recover fully with rest and fluids. - CDC provides additional traveler and clinician resources, including destination-specific health information, outbreak basics, and clinical overviews in the Yellow Book. - Page last reviewed September 18, 2026; content sourced from NCEZID and Division of Global Migration Health.

Most cases have been reported in San José province (see map). * HAV is contagious and spreads through close person-to-person contact and by eating contaminated food or drink * To prevent hepatitis A, you should: * Ensure that you are [vaccinated against hepatitis A](https://www.cdc.gov/hepatitis-a/vaccination/index.html). If you cannot get vaccinated, your doctor may recommend a medicine called immune globulin which can provide protection for up to 2 months. * [Practice good hand hygiene](https://www.cdc.gov/hepatitis-a/prevention/index.html) by thoroughly washing hands before preparing or eating food and after activities such as using the bathroom, caring for someone with an infection, and changing diapers. * Avoid sharing needles, syringes, or other drug equipment. * Practice safe sex. * Seek medical care if you develop [dark urine or clay-colored stools, diarrhea, fatigue, fever, joint pain, loss of appetite, nausea, abdominal pain, or jaundice](https://www.cdc.gov/hepatitis-a/signs-symptoms/index.html) (yellow skin or eyes) during or after travel. * If you think you have been exposed to HAV and haven't previously received hepatitis A vaccine, talk to your doctor about a prevention measure called post-exposure prophylaxis (PEP). PEP should be administered as soon as possible within 2 weeks of exposure to HAV. ### Traveler Information * [Health Information for Travelers to Costa Rica](https://wwwnc.cdc.gov/travel/destinations/traveler/none/costa-rica) * [CDC Hepatitis A Website](https://www.cdc.gov/hepatitis-a/index.html) * [Hepatitis A Outbreak Basics](https://www.cdc.gov/hepatitis-a/outbreak-basics/index.html) ### Clinician Information * [Clinical Overview of Hepatitis A](https://www.cdc.gov/hepatitis-a/hcp/clinical-overview/index.html) * [Hepatitis A](https://www.cdc.gov/yellow-book/hcp/travel-associated-infections-diseases/hepatitis-a.html) in the CDC Yellow Book (Health Information for International Travel) ![Map of Costa Rica](https://wwwnc.cdc.gov/travel/images/hepatitis-a-costa-rica.png) Costa Rica ([View larger](https://wwwnc.cdc.gov/travel/images/hepatitis-a-costa-rica.png "Map of Costa Rica")) What is hepatitis A virus? [Hepatitis A](https://www.cdc.gov/hepatitis-a/index.html) is a [vaccine-preventable](https://www.cdc.gov/hepatitis-a/vaccination/index.html) liver infection caused by the hepatitis A virus (HAV). HAV is spread when someone ingests the virus, even in small amounts. This usually occurs through close personal contact with an infected person (e.g., using drugs, caring for, or having certain sexual contact with someone who is infected with HAV) or by consuming contaminated food or water. [Symptoms](https://www.cdc.gov/hepatitis-a/signs-symptoms/index.html) may include dark urine or clay-colored stools, diarrhea, fatigue, fever, joint pain, loss of appetite, nausea, abdominal pain, or jaundice (yellow skin or whites of the eyes). Some people, particularly young children, may not have symptoms. Symptoms generally begin 2-4 weeks after initial exposure (range 15–50 days) and typically resolve within 2 months, though some people can feel sick for up to 6 months. People with a weakened immune system, chronic liver disease, and people over the age of 60 years are at greater risk for severe disease. There is no specific treatment for HAV; most people recover fully with rest and fluids. * * * Page last reviewed: September 18, 2026 Content source: [National Center for Emerging and Zoonotic
