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.

We will release three Influenza Surveillance Update during the 2019-20 influenza season. These reports will be released in late 2019, early 2020, and spring 2020. Additional reports may also be released as necessary.
