H3N2 Virus – Hospitals are seeing more cases of the flu lately, and the Indian Council of Medical Research confirms that a specific type of flu called H3N2 has been spreading for a couple of months. The flu usually lasts for 5-7 days and is more common during certain times of the year. Symptoms include coughing, nausea, vomiting, sore throat, fever, body aches, and sometimes diarrhea. The H3N2 virus is most common in people under 15 or over 50, and air pollution can make it worse. To stay healthy, it’s best to avoid crowded places, wash your hands often, cover your mouth when coughing or sneezing, and get a flu shot. If you get sick, there’s no need for antibiotics, but you can take medicine to help with symptoms.

H3N2 Virus symptoms

Many people are experiencing prolonged post-viral cough, breathlessness, and sneezing, which is rare in North India where more flu cases have been reported in January, February, and March. The symptoms of the current influenza virus strain are slightly different and more severe compared to previous years during the flu season, according to Dr. Sandeep Budhiraja, Group Medical Director of Max Healthcare and Senior Director of the Institute of Internal Medicine.

New Delhi is experiencing a rapid increase in flu cases, particularly the H3N2 strain, which is causing prolonged illness and coughing. The sudden shift in weather from extreme cold to warm is making the flu symptoms more prominent in people. Dr. SK Chhabra, Head of Department – Pulmonary at Primus Hospital in Chanakyapuri, New Delhi, explained that seasonal changes and pollution are negatively impacting people’s health and increasing the number of viral infections and chest congestion cases. The elderly, children, and pregnant women are particularly vulnerable to these infections.

What Is H3N2 Virus?

The H3N2 virus is a type of influenza A virus, causing respiratory infections every year since it was first discovered in humans in 1968. The virus comes from two protein strains, hemagglutinin (HA) and neuraminidase (NA), which have many subtypes. H3N2 is a combination of these two protein strains.

H3N2 symptoms

  • Fever
  • Chills
  • Cough
  • Nausea
  • Vomiting
  • Sore throat
  • Muscle and body aches
  • Diarrhoea
  • Runny nose and sneezing

Vaccine for H3N2

The annual flu vaccine protects against either three or four strains of flu, called trivalent and quadrivalent vaccines, respectively. The trivalent vaccine contains an H1N1, H3N2, and influenza B strain, while the quadrivalent vaccine includes an extra influenza B strain. The vaccine can reduce the risk of flu illness by 40-60% in the general population, according to the CDC. The vaccine provides better protection against H1N1 and influenza B viruses than against H3N2 viruses, which tend to mutate more and adapt better to egg-based vaccine production. Scientists are developing egg-free methods of vaccine production, but getting the seasonal vaccine is still the best way to prevent flu illness.

  • drinking enough fluids
  • taking over-the-counter medication to relieve symptoms such as fever, headache, and aches and pains

Doctors may prescribe an antiviral medication like Tamiflu for some cases of flu, particularly when started within 48 hours of developing symptoms.

Some people are at higher risk for developing serious complications, like pneumonia or worsening preexisting medical conditions such as asthma.
