The ongoing spell of heavy rain that has resulted in waterlogging in several parts of the city could mean a spike in leptospirosis cases in the coming days, the BMC has said, urging citizens to take preventive steps. Leptospirosis is a bacterial infection. It spreads through the urine of dogs, rats and farm animals.

Dr Nitin Karnik, professor and HoD of Medicine at Sion hospital, said they have been seeing at least two cases of leptospirosis, dengue, and malaria each day for the past three weeks. “We found that people are coming with complaints of high fever and loose motion which is unusual. Usually, people have red eyes, fever, and body ache and some develop jaundice and renal failure.”
