For the past two weeks, in Delhi, Noida and Gurugram, hospitals have seen a 40 percent rise in respiratory cases. Health experts blame the culprit largely on H3N2 virus. Although influenza is seasonal, this year’s H3N2 strain has been extremely aggressive, featuring high-grade fever and a cough that can persist for up to three weeks.
Symptoms: How to Identify H3N2
The H3N2 virus presents more seriously than other seasonal variants of the flu virus. If you live in the NCR, watch out for these symptoms and signs:
- Persistent Cough: A dry, hacking cough that lasts long after the fever passes.
- High Fever: Acute onset of fever with the onset of chills.
- Body Aches: Severe myalgia (muscle pain) and joint tiredness.
- Respiratory Distress: Sore throat, congestion in the nose and occasionally shortness of breath.
- Gastrointestinal Problems: Some patients, especially kids may have nausea, vomiting, or diarrhea.
Treatment and Recovery
Most H3N2 infections are self-limited. Drink plenty of fluids (water, electrolytes, soups) to prevent dehydration.
- Fever Management: Paracetamol should be recommended for fever and other common body pains. Refrain from self-care and antibiotics; H3N2 is a virus and antibiotics only work against bacteria.
- Antivirals: For higher risks, such as older adults, children or persons with comorbidities, doctors may prescribe antiviral medications, such as Oseltamivir.
- Rest: The immune system will heal if you take complete rest physically.
Prevention: Staying Safe in the Capital
Given Delhi-NCR's high density of population, the virus is transmitted rapidly through respiratory droplets.
- Mask Up: Masking up heavily in crowded places like the Delhi Metro or shopping malls greatly reduces the risk of inhalation.
- Hand Hygiene: Frequently wash your hands with soap or alcohol-based sanitizers.
- Vaccination: The annual flu shot is still the best defense. If you haven’t taken your influenza vaccine this year, health officials say you should now.
Social Distancing: Avoid close contact with those who cough or sneeze.
When to See a Doctor?
Most individuals recover over time at home, but consult a doctor now if you notice:
- Difficulty breathing or bluish lips.
- Chest pain, or persistent dizziness.
- Fever that goes away but then returns with a much worse cough.
- Confusion or severe lethargy.
