Communicable Diseases

A communicable disease could affect many people, causing mild illness, hospitalization, or in rare cases, death. The San Francisco Bay Area has a high probability of a naturally occurring, mild to moderate pandemic.  People in the Bay Area travel more internationally and come into contact with many people on a daily basis.  For more information, visit the San Francisco Department of Public Health's Communicable Disease Control and Prevention website:

Quick Tip:

  • Wash your hands before and after cooking, serving or eating food, or treating a cut or wound; and after using the bathroom, changing a diaper, or coming into contact with a sick person.
