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:
- January to March
- 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.
