Seasonal Influenza

Seasonal (or common) flu is a viral respiratory illness that can be transmitted person to person. Young healthy children, persons 65 years of age and older, and persons of any age with certain medical conditions are hospitalized with the flu because of severe complications. Annually, 36,000 people die with the flu in the U.S. Annual flu vaccines are available.


Avian Influenza

Avian (or bird) flu is caused by influenza viruses that occur naturally among wild birds. The risk from avian influenza is generally low to most people, because the viruses do not usually infect humans.


Pandemic Influenza

Pandemic flu is human flu that causes a global outbreak, or pandemic, of serious illness. Because there is little natural immunity, the disease can spread easily from person to person. Currently, there is no pandemic flu.
