Reports of an increase in Hepatitis A cases have been noted in Havana, Cuba, according to a health alert issued by the U.S. Embassy in Havana on August 27, 2025. The embassy stated that Hepatitis A is mainly transmitted through contaminated food and water. The risk of transmission is higher in areas with poor water supply systems, ineffective garbage collection, and a high presence of flies—conditions that exist in several parts of Havana.
The embassy advised travelers to consult the Centers for Disease Control and Prevention (CDC) website for more information about Hepatitis A, including its symptoms, prevention methods, and available vaccinations. Travelers are also encouraged to speak with their medical providers regarding travel plans and vaccination options. In addition, checking with travel insurance providers about evacuation options if illness occurs while abroad was recommended.
For assistance, the U.S. Embassy in Havana provided contact details including phone numbers and an email address for American citizens needing support. The State Department’s Consular Affairs office can also be reached for further information. The embassy suggested enrolling at step.state.gov to receive security updates related to travel in Cuba.
