Epidemiological Situation

During the first four months of 2017, the number of cases was similar to that observed during the same period in 2016 (130 vs. 135 in 2016). Agricultural activities and/or recreational or domestic water-based activities were found in the majority of cases, often involving walking in sandals or barefoot. Agricultural activity was identified in 73% of the patients surveyed, most often without the use of gloves or boots.

The significant seasonal resurgence, particularly in April, is partly due to increased rainfall in February, but also to the accumulation of waste in the immediate environment, reported in 40% of cases, and the presence of open trash cans, reported in 56% of cases, practices that promote the proliferation of rats present in around 90% of cases.

The poor implementation of personal protective measures and hygiene practices in living and working environments is the main factor contributing to infection with leptospires, the bacteria responsible for the disease.
