In tropical regions, leptospirosis is a prevalent zoonotic illness. The most prevalent reservoirs are rodents and other animals. Humans contracted this illness through coming into touch with water, dirt, or animal tissues that had been exposed to the sickness. It is distinguished by the participation of many systems. Given that it can appear as anything from an undetected infection to hepatocellular failure, early detection is crucial to halting the fulminant course. Here, we'll discuss a severe case involving a 25-year-old female patient who went to the hospital complaining of a fever with chills, a cough, shortness of breath, and bodily aches. Bilateral heterogenous opacity in the mid and lower zone was visible on the chest X-ray. A high resolution computed tomography (HRCT) scan of the chest revealed minor pleural effusion on both sides, as well as bilateral mid- and lower-zone alveolar opacities and a few regions of brochial dilatation that may have been caused by an alveolar haemorrhage. Highly positive results from a serum IgM leptospira test indicated leptospirosis.
