Seasonal (or common) flu is a respiratory illness that can be transmitted person to person. Most people have some immunity, and a vaccine is available.
Avian (or bird) flu is caused by influenza viruses that occur naturally among wild birds. The H5N1 variant is deadly to domestic fowl and, in rare cases, can be transmitted from birds to humans. There is currently no human immunity and no vaccine available.
A pandemic flu is a virulent 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.
The Los Angeles County Department of Public Health has produced a Public Heath Emergency Toolkit to assist schools in dealing with issues surrounding pandemic influenza and infectious diseases. To view the toolkit, please click on the following link:
