Winter Vaccination Plans for Jamaica Disrupted by Leptospirosis Outbreak

After Hurricane Melissa struck in late October 2025, Jamaica's Ministry of Health declared a health emergency across the island regarding leptospirosis (Weil's disease).

The passage of Hurricane Melissa led to flooding in many communities, increasing the risk of leptospirosis transmission. By early December 2025, the ministry reported (#36) 71 suspected, probable, or confirmed leptospirosis cases following the hurricane.

Among these cases, seven fatalities have been confirmed as related to leptospirosis.

Local media reported on December 5, 2025, that the ministry is monitoring the ongoing outbreak in St James (15 cases), St Ann (12), and St Elizabeth (8).

Dr. Ciro Ugarte, PAHO Health Emergencies director, recently stated in a press release, "Our priority is to ensure that communities have access to safe, quality health care while remaining vigilant to rapidly detect and respond to health threats that linger in the aftermath of the hurricane."

Additionally, Jamaica's National Surveillance Unit, Ministry of Health and Wellness, had recorded 452 suspected/probable cases of dengue and two suspected dengue-related deaths in 2025.

While the U.S. CDC has not issued a Travel Health Notice as of December 8, 2025, the UK's the Foreign, Commonwealth & Development Office says there is no vaccination or medication to prevent leptospirosis.

And when departing from the U.S., the second-generation dengue vaccine is currently unavailable.
