Officials on the Indian Ocean archipelago, Mayotte have reported an “abnormal” number of cases of the bacterial infection, leptospirosis in 2016 to date.
According to the Journal of Mayotte, “Since the beginning of the year, 147 cases were reported, a record. For the record, in 2015, our department had registered 90 sick throughout the year.”
Leptospirosis is caused by a corkscrew-shaped bacterium called Leptospira interrogans, is often referred to as “rat fever” due to the principal role rats play in spreading the disease (scientists refer this type of animal as a reservoir host). Other animals can also be important reservoirs of the disease.
These animals can spread the disease in their urine, contaminating water, soil, or food. People who live in close contact with domestic animals or wildlife are at higher risk for getting the disease.
People become infected by coming into contact with contaminated urine, water, food, or soil through breaks in the skin, eyes, mouth, or nose. Outbreaks of leptospirosis are usually caused by exposure to contaminated water, such as floodwaters. Person to person transmission is rare. Infected individuals initially experience fever, severe headache and muscle aches, abdominal pain, and occasionally a skin rash. Patients in the later stages of disease can suffer from jaundice, kidney failure, bleeding from the mouth or nose, bloody urine and can be fatal, especially without proper treatment.
