The Caribbean Public Health Agency (CARPHA) is urging caution in the Caribbean region, despite the low risk of hantavirus infection, as of May 8, 2026. CARPHA's executive director, Dr. Lisa Indar, stated that the risk to the Caribbean is considered low, with the virus being more commonly transmitted by rodents rather than urban rat populations. CARPHA was alerted to a cluster of respiratory illnesses affecting passengers and crew on a cruise ship in the central Atlantic Ocean, with hantavirus confirmed in one patient. CARPHA, recognizing the Caribbean's position as a leading cruise destination, encourages member states to remain vigilant. They are advising countries to review and strengthen vessel surveillance systems and public health protocols, especially at ports of entry. CARPHA's Tourism and Health Information System and the Caribbean Vessel Surveillance System (CVSS) provide early warnings of public health threats. These systems facilitate timely information sharing and support rapid responses by health authorities.
