Are Seasonal, Avian, and Swine (H1N1) Flu Different?Seasonal flu is a respiratory illness that can be transmitted person-to-person. Most people have some immunity and a vaccine is available. H1N1 (Swine) flu is a new influenza virus causing illness in people. This new virus was first detected in people in the United States in April 2009. This virus is spreading from person-to-person, probably in much the same way that regular seasonal influenza viruses spread. Humans may not have a natural immunity. A vaccine is expected to be available to at-risk populations, such as people under the age of 24, in October 2009. Avian (bird) flu is a respiratory illness among wild birds. The H5N1 variant is deadly to domestic fowl and can be transmitted from birds to humans. There is no human immunity. However, a vaccine was created in 2007. Pandemic flu is a virulent flu that causes a global outbreak, or pandemic illness. Because there is little natural immunity, it spreads easily from human to human. The World Health Organization has declared the H1N1 flu outbreak a pandemic. Pandemic Preparedness PlanGoals
