Background
Doctors in Chennai and nearby districts are reporting a steady rise in fever cases, with most linked to seasonal viral infections. Health officials said the increase is mainly due to Influenza A, including the H1N1 and H3N2 strains, along with cases of RSV and rhinovirus.
Dr P Sampath, additional director of public health, said fever cases in Tamil Nadu now appear earlier than usual. “The fever season, which once started in October, is now beginning by June or July. This year too, most patients show influenza-like illness,” he said.
Hospitals across the state have recorded a 25–50% increase in outpatients and a 10% rise in admissions, including intensive care. The state lab reported that nearly 30% of people with fever tested positive for Influenza A, while a few had Influenza B. A pre-monsoon survey will be carried out to study viruses in circulation.
Doctors said common symptoms include high fever, cough, sore throat, runny nose, headache, body pain, and tiredness. The majority of such cases are mild, and the condition gets better with rest, although those with weak immunity or chronic disease, such as diabetes, can experience severe complications such as pneumonia.
According to government hospitals in Chennai, more than 500 fever patients visit daily, and about half of them test positive for influenza. Children are sometimes admitted for nebulization and steroids, though fatalities remain low.
Health officials urged the public to wear masks in crowded spaces, take flu vaccines, and clear stagnant water to prevent dengue. The department stressed that no new virus is spreading in the state and that the situation is being closely monitored.
