The government of the Philippines reports continuing transmission of leptospirosis. From 1 January 2023 to 2 September 2023, there have been 3 728 cases of leptospirosis nationwide. Cases numbers began to increase again following storms and flooding in July.
The six regions affected by the current increase in case numbers are: the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM), National Capital Region, Ilocos Region, Region 4-A (Calabarzon), Central Visayas, Zamboanga Peninsula, Northern Mindanao and Davao Region.
Leptospirosis is a bacterial infection transmitted to humans from the urine of infected animals (often rodents). Infection often occurs from water contaminated by infected animal urine.
Travellers participating in adventure/ecotourism, water-based sports activities, athletic endurance events, mountain biking and military exercises have an increased chance of exposure, especially if travelling to high-risk destinations. Veterinarians and humanitarian relief/aid workers are at risk when travelling overseas to work.
Travellers at increased risk should be advised:
No licensed vaccine is available in the UK for leptospirosis.
