More Information

Flu is a viral infection caused by the influenza virus, which affects the respiratory system. It spreads through respiratory droplets when an infected person coughs or sneezes. Symptoms can range from mild to severe and include fever, chills, muscle aches, fatigue, and coughing. The flu can be especially dangerous for young children, elderly individuals, and those with weakened immune systems. Annual vaccination is the most effective way to prevent the flu, as the virus strains tend to change over time, necessitating updates to the vaccine. The flu is often confused with the common cold, but it is typically more severe and can lead to complications like pneumonia and hospitalization. In severe cases, the flu can be fatal, making it a critical public health concern worldwide.
