Context

New Caledonia reported 69 cases of leptospirosis in 2020, nearly 65 cases in 2019, and 75 in 2018. Leptospirosis is caused by a bacterium that spreads to humans through water and soil contaminated by infected animal urine. Symptoms typically appear 5-14 days after exposure but can develop up to 30 days after exposure. Symptoms generally include a headache, fever, muscle aches, chills, diarrhea, vomiting, and abdominal pain. However, some individuals can develop a more severe illness called Weil's disease, which can be life-threatening. Symptoms of Weil's disease may include meningitis (inflammation of the brain and spinal cord), kidney failure, and/or liver failure.

Advice

Avoid contact with contaminated soil and water. Seek medical attention if symptoms develop within one month of being in affected areas.
