Influenza Virus Illustration
Influenza, or the flu, is a group of viruses that affect the nasal passages and lungs. There are three types of influenza, designated A, B, and C. Most cases of the flu resolve within 1 to 2 weeks. Sometimes, people may develop very serious and even life-threatening complications, requiring hospitalization. Pneumonia is one potential complication of the flu. The risk of illness, complications, and death from the flu can be reduced by annual flu vaccination.
