CDPH California Influenza Surveillance Program

The California Department of Public Health (CDPHi) Influenza Surveillance Program is a collaborative effort between CDPH, the CDC, Kaiser Permanente, California local health jurisdictions and participating sentinel providers and laboratories.

Annual influenza epidemics follow a winter seasonal pattern in the United States with typical activity peaking during late December to early February. CDPH obtains and analyzes clinical, pharmacy and laboratory data year-round in an effort to determine the timing and impact of influenza activity and to determine how well circulating strains of the virus match those used in the current influenza vaccines.

The most current weekly report on influenza and other respiratory disease activity can be found below, under “Hot Topics & Updates.”
