H3N2 Influenza Virus: The H3N2 virus has been found to be the cause of a significant portion of the recent increase in influenza cases in the country. The H3N2 subtype of influenza A is currently the leading cause of respiratory disease in the country, according to the Indian Council of Medical Research (ICMR). Indian authorities have now confirmed two additional deaths, one in Haryana and another in Karnataka.
Influenza A subtype H3N2 is the main cause of current respiratory illness. The ICMR-DHR established general surveillance of respiratory viruses in 30 VRDL.

What is the H3N2 influenza virus?
The “Hong Kong flu” is another name for the H3N2 virus. Influenza genus A virus, which is a major contributor to human influenza and causes respiratory infections, includes the H3N2 subtype. Hemagglutinin (H) and neuraminidase (N), two types of proteins that are present on the surface of its coat, are the source of its name.

H3N2 influenza virus: causes
Droplets emitted when a person with highly contagious H3N2 influenza coughs, sneezes, or talks can spread the disease from one person to another. Additionally, the virus can be transmitted if a person touches their mouth or nose after coming into contact with a surface that has the infection. Complications from the flu are more likely to occur in pregnant women, young children, older adults, and people with underlying medical conditions.

H3N2 influenza virus: treatment
The H3N2 flu treatment plan includes getting enough rest, drinking plenty of fluids, and reducing fever with over-the-counter pain relievers. A doctor may also suggest antiviral medications if a patient has severe symptoms or is at high risk of complications.
The WHO recommends that neuraminidase inhibitors be prescribed as soon as possible (ideally within 48 hours of symptom onset) in suspected and confirmed cases to maximize therapeutic benefits.
Meanwhile, the Indian Medical Association (IMA) has urged doctors to avoid giving antibiotics to patients before determining whether the infection is bacterial because doing so can lead to the development of resistance. Most cases of fever, cough, sore throat, and body aches today are caused by influenza, which does not require antibiotics.
