As cases of H3N2 virus continue to spread across the country, medical experts are advising people to take precautions. Recent reports from the Indian Council of Medical Research (ICMR) say that the H3N2 virus is causing more hospitalizations than other strains of the flu.
People with weak immunity are at higher risk for complications like pneumonia, bronchitis and seizures which can be life-threatening.
City doctors recommend that the 4-in-1 flu vaccination which can protect against H3N2 and three other strains of flu can help.
Dr M. Surendranath, Paediatrician, Vijay Marie Hospitals said, “Flu viruses like the H3N2 subtype is spreading and may cause severe illness in children leading to hospitalisation. I would like to advise parents to speak to their doctors about the 4-in-1 flu vaccination which can protect against H3N2 and three other flu virus strains.”
ICMR data shows that in the last three months, 10 per cent of SARI patients hospitalized with H3N2 complications needed oxygen and seven per cent required ICU care.
People most at risk for H3N2 and other strains of flu are children below 5 years of age, ageing adults, pregnant women, and those with chronic conditions like diabetes, asthma, kidney and heart diseases.
Dr Prassanna Kumar Reddy, a chest physician at the Breathe Free Lung Clinic said, “Flu can be serious in people with weak immunity. In these people, the H3N2 subtype of flu can lead to hospitalisation. I advise all adults above 50 years, pregnant women and those who suffer from chronic conditions like diabetes and asthma to consult their doctor about the 4-in-1 flu vaccination.”
H3N2 is a subtype of the Influenza A virus. Every year during seasonal changes the temperature change causes flu viruses to increase and spread. Some subtypes spread more than others. All flu viruses, including H3N2, spread through infected individuals when they cough, sneeze or talk. They can also spread when uninfected people touch an object or surface contaminated by these viruses and then touch their nose or mouth.
