Influenza (the flu) is an infection of the nose, throat,
and lungs caused by influenza viruses. There are
many different influenza viruses that are constantly
changing. Flu viruses cause illness, hospital stays and
deaths in the United States each year.
The flu can be very dangerous for children. Each year
about 20,000 children younger than 5 years old are
hospitalized from flu complications, like pneumonia. See the Flu guide for parents from the CDC |
