Dengue and Leptospirosis Outbreaks in India

COVID-19 Cases in Bengal: Despite no major spike, multiple COVID-19 cases have emerged in Bengal after a period of low activity. A 15-year-old boy was admitted to a hospital off EM Bypass, and another patient tested positive in a Kankurgachhi nursing home. Two additional cases were reported from Mograhat in Diamond Harbour, bringing the active case count to four. Previously, there was only one active case.
The teenager from Rishra was admitted to Peerless Hospital's OPD with symptoms including high-grade fever, cough, loose stool, vomiting, and severe dehydration. A respiratory panel test confirmed SARS-CoV-2, ruling out other viruses. According to paediatric critical care specialist Saheli Dasgupta, the boy's gastrointestinal issues were more prominent than respiratory ones. He is currently isolated and treated following protocol. Microbiology head Bhaskar Narayan Chaudhuri noted this was the first SARS-CoV-2 detection in their lab since September 2024.
Health department sources reported a 20-year-old woman and a child from Mograhat tested positive on May 21. They are in stable condition and do not require hospitalization. District health officials are monitoring the area for influenza-like illnesses (ILI) as part of a pan-India surveillance. Another woman from Kolkata was treated and discharged from Woodlands Hospital in early May. Critical care specialist Soutik Panda stated that while the virus is generally self-limiting for healthy individuals, it could be severe for those with comorbidities, especially COPD. The health department emphasizes there is no reason to panic.
Kerala Braces for Epidemic Season: Kerala is preparing for another epidemic season with the early arrival of the Southwest monsoon. The Health department has warned of potential spikes in dengue and leptospirosis, which are regular occurrences during the monsoon months. All four serotypes of dengue virus are endemic, and Kerala has experienced cyclical outbreaks since 2013.
Leptospirosis and water-borne diseases, especially hepatitis A, have become significant public health concerns. The Health department has issued public health alerts and instructed all districts to enhance preparatory measures. Hospitals are preparing for increased admissions and ensuring sufficient medicine stocks. They are also addressing potential waterlogging issues.
Pre-monsoon cleaning activities are ongoing, with a focus on source reduction. The Health department stresses the importance of self-care measures, such as using insect repellants and protective clothing, to prevent mosquito bites. Those engaged in farming, dairy farming, and outdoor cleaning activities should wear protective gumboots and gloves and consider doxycycline prophylaxis to prevent leptospirosis.
Children and adults should wash their hands and feet with soap after contact with rainwater, and children should avoid playing in stagnant pools. The Health department also advises boiling drinking water to prevent hepatitis A, as water source contamination is a risk during rains. Strict personal hygiene is crucial for those recovering from hepatitis A, and they should avoid handling food or kitchen utensils. Rain relief camps should follow guidelines to prevent infectious disease outbreaks. The warning was published on May 24, 2025.
