Pandemic influenza could affect our world community
Pandemic Influenza
What is Pandemic Influenza (Pandemic Flu)?
A pandemic influenza occurs when a new influenza virus:
- Develops and there is little or no immunity (protection due to previous infection or vaccination) in the human population;
- It is easily passed from human to human;
- Is found in many countries; and,
- Causes serious illness in humans.
Presently avian influenza (H5N1) is not a pandemic influenza because it is mostly a disease of birds and is not easily passed between humans.
What are Seasonal Influenza and Avian Influenza (Bird Flu)?
Seasonal influenza, commonly referred to as the flu, is an infectious disease. In the United States, flu season usually occurs between December and March. The influenza virus is one that has the ability to change easily. However, there is usually enough similarity in the virus that the general population is partially immune from previous infection or vaccination. Each year experts monitor the influenza virus and create a new vaccine to address changes in the virus. For this reason people are encouraged to get a flu shot each year.

Avian Influenza (H5N1), or bird flu, is primarily a disease of wild birds and domesticated poultry. Click to link to the Avian Influenza Webpage.
How is San Francisco Preparing for a Pandemic?
San Francisco agencies are closely monitoring avian influenza and preparing for a pandemic in our region. A San Francisco City Department Avian/Pandemic Influenza Task Force is coordinating planning to ensure a multi-disciplined approach to continuity of operations. The health department is also reaching out to hospitals and clinicians, front line workers, businesses, organizations that meet the needs of special populations, and the general public. For more information see above for the fact sheet "Pandemic Influenza: San Francisco City & County Preparedness".
How do I Prepare for a Pandemic?
San Francisco will work its hardest to protect our community, however, individual preparedness is the best chance we have against pandemic flu. Here are some simple steps you can take to prepare yourself, your family, and your home for pandemic flu:
- Learn about pandemic flu
