Seasonal Influenza Concerns in Delhi-NCR

Recent reports indicate a rise in seasonal influenza cases in the Delhi-NCR area, necessitating a renewed effort to promote adult vaccination in India. The predominant strains are Influenza A and Influenza B.

Understanding Influenza

  • Influenza, commonly known as the flu, is a contagious respiratory illness caused by viruses.
  • It is often confused with the common cold but has distinct differences in symptoms and severity.
  • Symptoms include sudden cough, sore throat, high fever, muscle pain, body aches, headaches, fatigue, and stuffy nose.
  • Influenza can range from mild to serious illness, sometimes requiring hospitalization and, in severe cases, may lead to death.

Seasonal Peaks in India

  • India experiences two peaks of seasonal influenza: 
    1. January to March
    2. August to October, during the latter part of the southwest monsoon

Influenza Surveillance and Preparedness

India has developed near real-time surveillance of Influenza-like Illness (ILI) and Severe Acute Respiratory Infections (SARI) in health facilities, which was strengthened during the COVID-19 pandemic. Additionally, there is real-time surveillance through diagnostic laboratories across the country.

Importance of Vaccination

  • Surveillance helps in monitoring circulating strains and defining seasonality.
  • Vaccination synchronization with relevant strains is crucial.
  • High-risk groups include children, senior citizens, and individuals with chronic respiratory conditions.

Government's Role and Recommendations

  • The government needs to be prepared to handle outbreaks by anticipating them and promoting preservation among high-risk groups.
  • Increasing awareness on influenza vaccination is key.
  • While children's vaccination is prioritized, adult immunization is often neglected.
  • State governments currently determine the provision of adult vaccinations.
  • Targeted awareness campaigns should emphasize the urgency and importance of vaccines, particularly for high-risk groups, as vaccines save lives.
