Punjab Chief Minister Bhagwant Mann has been diagnosed with leptospirosis, a bacterial infection caused by the Leptospira bacterium. The 50-year-old Aam Aadmi Party (AAP) leader was admitted to Fortis Hospital in Mohali for a routine check-up after experiencing tropical fever, and subsequent blood tests confirmed the diagnosis. According to a health bulletin from the hospital, Mann is currently receiving antibiotics, and his vital signs are reported to be "completely stable."What Is Leptospirosis? Leptospirosis is one of the most prevalent zoonotic diseases worldwide, often linked to poor sanitation and agricultural practices that involve contact with animals or contaminated water. The bacteria can survive in contaminated water or soil for weeks to months, primarily spreading through the urine of infected animals. Humans can contract the disease through direct contact with infected urine or through contaminated food, water, or soil.There are two main forms of leptospirosis: icteric leptospira, which presents with jaundice, and anicteric leptospira, a milder variant without jaundice. Leptospirosis can also manifest as Weil's disease, a severe complication.What Are Symptoms Of Leptospirosis? Symptoms typically develop 2 to 30 days after exposure and can range from mild to severe. Initial signs often include high-grade fever, red eyes (conjunctival suffusion), calf tenderness, headache, dry cough, nausea, and diarrhea. In more serious cases, the infection can lead to complications such as jaundice, kidney or liver damage, meningitis, respiratory issues, and hemorrhages.Pulmonary haemorrhage—acute bleeding from the lungs—can also occur, posing life-threatening risks such as respiratory and renal failure. The illness may last from a few days to several weeks, and without treatment, recovery can take months, according to the CDC.What Precautions Should Be Taken? To reduce the risk of leptospirosis infection, individuals are advised to take several important precautions. According to the Centers for Disease Control and Prevention (CDC), it is essential to avoid wading through dirty rainwater, especially during the rainy season, and to wear gumboots in such conditions.Proper care of any injuries or cuts is crucial, and frequent handwashing, particularly after handling food or working in potentially contaminated environments, is highly recommended. Additionally, individuals should avoid contact with animals that appear sick or are known carriers of the bacteria.Vaccination is also vital—pet owners should ensure their pets are vaccinated against leptospirosis, especially if they are frequently exposed to water or wildlife. Staying hydrated by drinking plenty of clean water and preventing water stagnation around the home can further minimize the risk of infection.
