The California Emerging Infections Program (CEIP) is one of ten EIP sites. CEIP is funded by the Centers for Disease Control and Prevention (CDC) and is sponsored by Public Health Foundation Enterprises, Inc. (PHFE). As part of the EIP network, CEIP has been an invaluable national resource for the surveillance, prevention, and control of emerging infectious diseases. CEIP functions under a cooperative agreement with CDC and is a collaboration among the California Department of Public Health, the UC Berkeley School of Public Health, the UC San Francisco School of Medicine, and multiple Bay Area local health jurisdictions.

CEIP was initiated in 1994 with Directors Duc Vugia, MD, MPH and Arthur Reingold, MD, Health Program Manager Gretchen Rothrock, MPH, and seven employees. It now employs over 40 staff.
