New Delhi: The flu season has gripped the capital, with a surge in upper respiratory tract infections. Patients are experiencing runny noses, sore throats, severe coughing bouts, high fever, blocked sinuses, headaches, and swollen tonsils. This time, however, the symptoms are lasting up to 10 days and bringing high-grade fever, adding to concerns.
Severe Cases & Rising Hospital Admissions
Doctors report that flu cases, particularly Influenza B and H1N1 (swine flu), are on the rise, with more patients requiring hospitalization. Dr. Suranjit Chatterjee, Senior Consultant, Internal Medicine, Indraprastha Apollo Hospitals, notes an increase in severe cases over the past two weeks.
“Younger patients, aged 35 to 40, are suffering from extreme body aches, persistent coughs, and worsening symptoms,” says Dr. Chatterjee. “Many develop chest pain, secondary infections, and acute restlessness, prompting hospital visits even when intensive care isn’t necessary.”
Influenza B & H1N1 – The Dominant Strains
- Influenza B: Primarily affects humans, mutates slowly, and is less common than Influenza A.
- H1N1 (Swine Flu): A subtype of Influenza A, known for causing severe symptoms. The 2009-10 outbreak saw a major H1N1 mutation, and the virus continues to circulate.
Can the Flu Lead to Pneumonia?
Yes. Some flu viruses infect the lungs, causing inflammation and fluid build-up. This weakens the immune system, allowing bacteria to thrive, leading to pneumonia and secondary infections.
Why the Sudden Spike?
- Viral Mutation – The flu virus constantly changes, making older immunity less effective.
- Weather Fluctuations – A sudden shift from winter to warmer temperatures affects immunity.
- Environmental Factors – Air pollution and pollen accelerate viral transmission.
