India Witnesses Its First H3N2 Deaths Amid Increase In Number Of Cases Across Country. Top Developments

The cases of fever and flu, according to the Indian Council of Medical Research (ICMR), are caused by Influenza A subtype H3N2. These are the most recent developments since the virus's spread.

The country recently witnessed its first death cases caused by the H3N2 influenza virus in Karnataka and Haryana, and several states across the country have reported a high number of influenza cases in the last two-three months, with symptoms including a persistent cough, sometimes accompanied by fever.

The instances of fever and flu, according to the Indian Council of Medical Research (ICMR), are caused by Influenza A subtype H3N2.

Dr. Dhiren Gupta of Ganga Ram Hospital explained why the virus is spreading post-pandemic: "Since 2 years due to Covid there has been no exposure to influenza to children, as a result of this the sudden outbreak of H3N2 virus, which is a normal variant of influenza variant, has caused the increase in the number of cases in children."

He added: "The H3N2 is antigenic drift & a mild mutation, but is not life-threatening. Whichever virus it is if there’s comorbidity then the chances of death are high. The vaccine against H3N2 has less efficacy & our vaccination is low this year".
