Influenza and leptospirosis have become the leading causes of death in Kerala this season, with nearly 300 fatalities reported as of September 15. Health officials recorded 10,244 influenza cases, including strains A H1N1, A H2N3 and Influenza B, and 109 deaths attributed to the virus. Leptospirosis deaths reached 100 confirmed cases, with an additional 78 probable deaths, a figure that officials say is lower than in previous years.
Nationwide influenza cases have risen sharply, especially H1N1, with most states reporting spikes. In Kerala, the increase has disproportionately affected senior citizens, prompting public health experts to call for expanded vaccination for the elderly. Unpredictable weather, high temperature and humidity, and possible viral mutations are cited as contributing factors.
The state’s guidelines recommend testing only severe cases; mild flu symptoms can be managed at home with isolation and supportive care. Oseltamivir is advised for pregnant women, those with high fever or persistent symptoms, and for patients showing red‑flag signs such as breathlessness, chest pain or low oxygen saturation. Doctors urge patients not to self‑treat and to seek early medical care, while the private sector encourages the elderly and those with comorbidities to receive the annual flu vaccine if affordable.
Leptospirosis diagnosis is often delayed because early symptoms mimic viral fevers. To counter this, doctors are now advised to prescribe doxycycline to all patients with fever lacking respiratory signs, as the antibiotic is effective at any stage. Workers exposed to the pathogen—farmers, cleaners, gardeners and dairy farmers—continue to ignore prophylaxis recommendations. Local governments are urged to supply protective gear to these occupational groups.
