Marin Flu Surveillance Data

Marin Influenza Surveillance

Marin County Department of Health and Human Services tracks influenza activity by analyzing laboratory testing data and visits to local emergency departments for influenza-like illness.  During the influenza season, we produce an influenza surveillance report that summarizes influenza activity in Marin County, California, and the United States.
We usually observe a peak in influenza activity between late December and February.
