NEW DELHI – Hospitals across Delhi have sounded an alert as the national capital grapples with a significant outbreak of the H3N2 flu, a type of influenza A virus. Health officials are urging citizens to take precautions and seek medical help early, as this strain has shown a tendency to cause more severe and prolonged illness compared to other seasonal flu viruses.
Understanding the Threat
The H3N2 virus is known for its ability to mutate, making it more difficult to manage. It spreads easily through respiratory droplets from coughing, sneezing, or speaking, and can also be transmitted through contact with contaminated surfaces. The symptoms typically appear within one to four days of exposure and can include:
• Severe and sudden fever
• Persistent cough
• Sore throat
• Body aches and fatigue
• Headache
• Runny or stuffy nose
While most healthy individuals can recover within a week, the virus poses a significant threat to vulnerable populations, including older adults, young children, and pregnant women, as it can lead to severe complications like pneumonia. Doctors have also noted that many patients are experiencing a lingering cough and weakness even after the fever subsides.
Prevention and Recovery
Medical experts advise citizens to remain vigilant and take preventive measures to curb the spread of the virus. These include:
• Getting an annual flu vaccine, which often includes protection against H3N2 strains.
• Frequent handwashing with soap and water.
• Avoiding close contact with infected individuals.
• Wearing masks in crowded or confined areas.
• Disinfecting frequently touched surfaces.
For those who do get sick, resting and staying hydrated are crucial. While over-the-counter medications can help manage symptoms, doctors may prescribe antiviral drugs. These are most effective if taken within 48 hours of the onset of symptoms, as they can help reduce the severity and duration of the illness.
