Seasonal influenza is an acute viral infection that spreads easily from person to person1. Seasonal influenza viruses circulate worldwide and can affect people in any age group1. Symptoms include sudden onset of fever, cough (usually dry), headache, muscle and joint pain, sore throat and a runny nose. The cough can be severe and can last 2 or more weeks. Most people recover from fever and other symptoms within a week without requiring medical attention. However, influenza can cause severe illness or death in high-risk groups2.
HOW CAN I AVOID GETTING THE FLU?
The best way to avoid getting the flu is to get the flu vaccine every year. Influenza viruses evolve constantly, and twice a year.
WHO MAKES RECOMMENDATIONS TO UPDATE THE VACCINE COMPOSITIONS?
The World Health Organization recommends annual influenza vaccination for subjects at risk, such as:
- pregnant women,
- children 6 months to 5 years of age,
- the elderly (65 years of age and over),
- people of all ages with medical conditions such as asthma or other chronic lung or heart conditions.
