Understanding Flu and Its Prevention

The video explains that flu is a contagious respiratory illness caused by influenza viruses. It spreads through droplets when infected people cough or sneeze. The virus infects cells, causing inflammation and symptoms. Severe cases can lead to lung damage and other complications. The immune system fights the virus with antibodies. Vaccination reduces the risk of flu and its severity. Everyone over six months should get vaccinated annually. Learn more at cdc.gov.
