H1N1 cases are unusually high in India this year, but there is currently no indication of a new pandemic or major epidemic threat, according to Dr Randeep Guleria. He said many infections are likely going unreported because people with mild symptoms often recover without getting tested.
The influenza virus commonly spreads during the monsoon and winter months. Most patients experience a mild illness and recover within five to seven days. However, older adults, children and people with underlying health conditions need to monitor symptoms carefully.
Dr Guleria said testing is not necessary for everyone with fever or cough. People with persistent fever, chest tightness or breathing difficulties may need medical evaluation and testing. In high-risk or seriously ill patients, doctors may consider starting oseltamivir, commonly known as Tamiflu, early rather than waiting for test results. The antiviral should only be taken on medical advice.
He also stressed the importance of annual flu vaccination. While vaccination may not completely prevent infection, it can lower the risk of severe disease, hospitalisation and ICU admission.
People with flu symptoms should stay home to reduce transmission, particularly around children and vulnerable family members. Good hand hygiene, covering coughs and sneezes and wearing masks in crowded places can also help.
Antibiotics should not be taken without medical advice because they do not treat viral influenza.
