Basic Terms
Seasonal flu is a respiratory illness transmitted between humans. Annual vaccines are available and recommended for all ages. Outbreaks of the seasonal flu are caused by subtypes of influenza viruses that already exist.
Avian influenza (bird flu) is caused by viruses that occur naturally in wild birds. The H5N1 variant is deadly to domestic fowl and in certain circumstances can be transmitted from birds to humans. Currently, there is no immunity to or vaccine available for the highly pathogenic H5N1 virus.
Pandemic flu is an influenza virus that is spreading easily from person to person. There is little immunity, limited or no vaccine; serious illness and complications would be possible.
