Influenza is a contagious infection of the nose, throat, and lungs. There are two main types: A and B. Each type includes different strains that change from year to year.
Influenza is not the same as "stomach flu," which is used to describe illnesses with vomiting or nausea. Influenza is a specific respiratory disease and typical symptoms include: fever, chills, muscle aches, headache, cough, sore throat and general weakness. It is spread thorugh contact of an infected person by coughing and sneezing.
Influenza can be dangerous and may have life-threatening complications, such as pneumonia. Seasonal influenza vaccination can reduce the complications and hopitalizations associated with influenza. Vaccination is recommended for all persons six months of age and older.
