Leptospirosis after flooding in Puerto Rico

There are 10 suspected cases of leptospirosis after drinking from streams in Canovanas and Loíza. Four of the patients have died. Without electricity and running water 3 weeks after the hurricane, some of the patients became ill after turning to local streams to relieve their thirst.

Advice

Leptospirosis is acquired through skin exposure (especially if there are open wounds) to water or damp soil that has been contaminated by an infected animal’s urine. For travellers, this exposure is higher after a period of heavy rainfall or flooding. Travellers can reduce the risk of exposure to leptospirosis during floods or heavy rainfall by avoiding contact with flood waters, e.g., wearing waterproof boots and other protective clothing. Other activities that may increase the risk of exposure include recreational water activities, such as rafting or swimming during floods. Avoid consuming contaminated water.
