Bengaluru accounts for more than 3,000 of Karnataka’s 4,125 H1N1 cases

Greater Bengaluru has reported 2,033 H1N1 cases this year, while Bengaluru Urban district has recorded another 982, taking the city region’s tally to more than 3,000.

Karnataka has recorded 4,125 cases so far in 2026, nearing the 4,583 infections reported across the state through all of 2025. The state government plans to review surveillance and preparedness with health officials this week, as the seasonal peak is expected to continue until September.

Concern grew after a Bengaluru school shut following H1N1 cases among students. Doctors believe infections may be higher than the official count because people with mild symptoms may not get tested.

Dr Veena, deputy director of the Integrated Disease Surveillance Programme, said there was “no need for panic” and that laboratories had not found anything unusual in the influenza A virus. The health department has advised residents with persistent fever, cough, sore throat, headache, runny nose, body aches or fatigue to seek medical care.

Officials have also been asked to ensure hospitals are prepared for admissions, including patients with severe acute respiratory infection.
