COVID-19 Data

In an ongoing effort to understand COVID-19 transmission and improve clinical outcomes in our community, Lake County Public Health tracks demographic, geographic and clinical information about confirmed COVID-19 cases. Public health officials and staff are monitoring data daily, and will update the website data on business days. Lake County Snapshot data is updated every business day by 8:00 p.m. 


The epi curve and testing data will be updated weekly. Due to decreasing cases in the county and the need to protect people's health information, we will be updating the demographic information on the 1st and 3rd weeks of the month. We continue to monitor the data on a daily basis for case investigation and contact tracing.

Please be aware that the data presented here is not real-time and may not reflect the most recent information.
