Telangana Leptospirosis Alert: Leptospirosis Cases Rise Sharply in Telangana During Monsoon

Telangana Leptospirosis Alert: Telangana is witnessing a noticeable rise in leptospirosis cases during the monsoon season, prompting health concerns across the state. The bacterial infection is particularly associated with exposure to water or soil contaminated by the urine of infected rodents.

The increase in reported cases has been significant over the past few years. Telangana recorded only two leptospirosis cases in 2023. The number increased to 249 in 2025, representing a sharp rise over the two year period. By June this year, 101 cases had already been reported in the state, indicating that the infection continues to remain a concern during the rainy season.

Although Telangana has recorded fewer cases than some other states in terms of overall numbers, the growth seen over the recent period has drawn attention. Kerala reported 4,001 cases in 2025, while Tamil Nadu recorded 2,862 cases. Karnataka reported 2,302 cases and Maharashtra recorded 2,184 cases during the same year. Several other states, including Jharkhand, Madhya Pradesh and Gujarat, also reported increases.

Doctors say the risk of leptospirosis can rise considerably after heavy rainfall and flooding. When floodwater comes into contact with contaminated soil, drains or other surfaces, people who walk through the water without adequate protection may come into contact with the bacteria.

Urban flooding and poor drainage can further increase the risk. Areas where stagnant water remains for long periods may provide conditions in which people are more likely to come into contact with contaminated surroundings. Rodent activity and sanitation problems can also contribute to the spread of the infection.

Medical professionals in Hyderabad have reported seeing leptospirosis patients during the rainy season. Doctors at government and private hospitals are reportedly encountering several suspected cases each month, particularly among people who have recently been exposed to floodwater or unhygienic surroundings.

One recent case involved a 27 year old man who developed a high fever, severe body pain and worsening kidney function after exposure to floodwater. His initial symptoms were considered similar to dengue or a viral infection. When his condition did not improve as expected, doctors considered the possibility of leptospirosis after learning about his contact with floodwater.

Further testing confirmed the infection. He was subsequently treated with antibiotics and supportive care for his kidney condition and recovered, according to the information provided by doctors.

One of the major challenges with leptospirosis is that its early symptoms can resemble several common illnesses. Patients may initially experience high fever, headache, muscle pain, vomiting and redness in the eyes. Because these symptoms can appear similar to dengue, malaria, typhoid or other viral infections, the actual cause may not always be identified immediately.

Doctors say certain warning signs can make leptospirosis more likely. Yellowing of the eyes or skin, reduced kidney function and worsening symptoms after exposure to contaminated water should prompt doctors to consider the infection.

The disease can become serious if treatment is delayed. In severe cases, leptospirosis can affect the kidneys and liver and may also cause complications involving the lungs and other organs. Early recognition and appropriate antibiotic treatment can reduce the risk of serious complications.

The rise in cases also highlights the importance of preventing exposure during the monsoon. People should avoid unnecessary contact with floodwater, particularly in areas where drainage and sanitation are poor. Those who have to walk through contaminated water should take appropriate protective measures and avoid direct exposure as much as possible.

Health experts also stress the importance of maintaining cleanliness around residential areas. Controlling rodents, preventing the accumulation of stagnant water and improving drainage can help reduce conditions that contribute to the spread of the infection.

People who develop a persistent high fever or severe body pain after coming into contact with floodwater should inform their doctor about that exposure. This information can help doctors consider leptospirosis along with other common causes of fever.

The rise in Telangana cases does not mean every fever during the monsoon is leptospirosis. However, the recent increase shows why the infection should not be overlooked, particularly when a patient has a history of contact with contaminated water or soil.

With the monsoon continuing, health authorities and hospitals are likely to remain alert for further cases. Timely testing, appropriate treatment and greater awareness among the public can play an important role in preventing the infection from becoming severe.
