We have been planning for pandemic influenza for decades and it is now upon us. This new strain is a hybrid virus with its major surface hemagglutinin antigen sequences derived from swine human and avian flu sources. This new virus is highly communicable by human-to-human transmission fortunately at least thus far it appears to have relatively low pathogenicity potential with an overall low mortality rate in the single digits. The growing pandemic is centered primarily on young healthy adolescent populations. This segment of the population is typically highly mobile and exposed to crowded environments schools social gatherings and traveling and is infrequently immunized with annual influenza vaccines. The degree of protection afforded by previous vaccination with prior influenza A H1N1 strain antigens is currently the matter of some debate. It is conceivable perhaps even likely that as the virus spreads to the very old the very young and other vulnerable populations pregnant women immunocompromised patients those with chronic cardiopulmonary disease and so on the mortality rate will rise. Fortunately the current epidemic strain of swine influenza remains susceptible to the .
