Key Questions Answered
Between January and June 2026, India recorded 23,952 dengue cases and 31 deaths. Five southern states—Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, and Telangana—together accounted for 15,137 of these cases.
WHO surveillance covering 1–14 September 2026 found that the A(H1N1)pdm09 strain accounted for 75 per cent of influenza-positive samples in India. This figure is well above the 50 per cent regional average recorded for South-East Asia.
To prevent dengue, households should eliminate stagnant water breeding sites by keeping water storage containers covered, emptying containers weekly, and clearing drains. For influenza, annual vaccination is the primary tool, accompanied by respiratory hygiene like frequent handwashing, covering the mouth when coughing, and staying home when feverish.
