H3N2 Virus: Expert Shares 6 Smart Prevention Tips to Stay Protected This Season

As the grip of flu season takes hold, medical experts are sounding an alarm about a spike in H3N2 cases nationwide. Known for causing severe cough, high fever, and lingering weakness, this viral flu has resulted in a surge in hospitalisation rates, especially among children and the elderly. Physicians advise that, even though the virus is easily transmitted in such close environments as schools, offices, and public transportation, most individuals are still neglecting simple preventive practices that might be the difference between a minor infection and a full-blown health crisis.

In an exclusive interaction with the editorial team of Onlymyhealth, our expert, Dr Bhumesh Tyagi, Senior Consultant and General Physician at Sharda Hospital - Noida, explained that by adopting a few conscious habits, you can reduce your chances of contracting and transmitting this infection significantly.

Why H3N2 Prevention Matters

The H3N2 strain is easily transmitted through cough droplets, contaminated surfaces, and close contact, making it highly contagious in high-density environments such as schools, workplaces, and public transportation. Healthy people are likely to recover with rest and treatment, but those in vulnerable populations, such as the elderly, young children, pregnant women, and individuals with pre-existing illness, have a greater risk of developing complications such as pneumonia or exacerbation of their condition.

Key H3N2 Prevention Tips

Here are a few prevention tips shared by Dr Tyagi exclusively that you should follow to steer clear of this viral infection:

1. Practice Good Hand Hygiene

Wash your hands often with soap and water for a minimum of 20 seconds. In its absence, use alcohol-based sanitiser. Do not touch your face using unwashed hands.

2. Wear Masks in Public Places

COVID-19 taught us better. Wearing a mask during travel by public transport, in workspaces, or at events lessens the chance of transmission.

3. Practice Respiratory Manners

Cover your mouth and nose while coughing or sneezing using a tissue or your elbow to prevent spreading droplets. Dispose of tissues immediately.

4. Strengthen Immunity

Eat a balanced diet rich in vitamin C, zinc, and antioxidants. Staying hydrated and getting adequate sleep helps your body fight infections better.

5. Avoid Self-Medication

Do not take antibiotics or antivirals without consulting a doctor. Misuse can worsen resistance and delay recovery.

6. Stay Home If Symptomatic

If you have flu-like symptoms like fever, cough, or body pain, stay home and minimise contact with others to avoid transmitting the virus.

Bottomline

H3N2 is a more virulent strain than the common flu, but it can be controlled and prevented with easy lifestyle changes and responsible practices. Being vigilant, building immune strength, and following hygiene practices are your strongest shields against flu viral seasons. Reach out for medical help if you have a persistent fever or any similar symptoms.
