Vice chairperson of medicine from Sir Ganga Ram Hospital, Dr Ambuj Garg, said the H3N2 has been spreading more this time. He also advised patients to take rest and consult a doctor if the condition doesn't improve in five to six days.

What is the H3N2 virus?

The H3N2 virus is a subtype of influenza that causes respiratory illness in humans. It can cause a variety of symptoms, including fever, cough and cold.

Precautions

Precautions for staying safe from the H3N2 flu virus include wearing masks in public, drinking warm water and having nutritious food, warm milk, Doctor Ambuj Garg, vice-chairperson of medicine at Sir Ganga Ram Hospital, said. To further prevent its spread, covering the nose and mouth when sneezing is essential, along with frequently rinsing hands with soap and water. If symptoms persist beyond five days, the patient should consult a doctor. The doctor also emphasised that avoiding crowded places and wearing masks is not mandatory at this stage.

Treatment

For treating patients with severe symptoms of the H3N2 virus, doctors prescribe antiviral medication that should be taken as advised by the doctor. Further, Oseltamivir, a type of antiviral drug, is usually prescribed for the treatment of H3N2. “But, until a blood report shows any sign of secondary infection, antibiotics should not be taken,” Dr. Shashikant Nigam, Consultant for Internal Medicine at Apollo Hospital, Ahmedabad, said.
