Reporting Clusters of COVID-19 and Acute Respiratory Illness (ARI) to LAC DPH
Per the LA County Health Officer Order, sites are required to report within 24 hours when the following criteria are met.
In an epidemiologically linked group (e.g. individuals sharing common areas or living space):
- A minimum of 5* cases (at least 20% of the group) meets case definition for acute respiratory illness within a 7-day period.
- At least 10% of the average daily population are absent and/or reporting symptoms of acute respiratory illness, with a minimum of 5* ill, within a 3-day period.
For case definitions and full reporting instructions, visit the COVID-19 and ARI Reporting Page.
How to Report
Report to LAC DPH online using the Shared Portal for Outbreak Tracking (SPOT). For assistance with reporting, see our reporting resources:
- Toolkit for First-time Reporters
- Quick Guide: First-time Reporters
- Quick Guide: Adding Cases to Existing Reports
- Quick Guide: Updating Close Contact to Case
- Quick Guide: Reporting a New Cluster as an Existing User
- Quick Guide: Bulk Upload Reporting
Once LAC DPH receives a cluster report, it will be reviewed to determine the risk of onsite transmission based on number of cases, where residents were housed at time of infection, staff work location and duties, and, how/if the cases interacted with each other.
If the cluster meets outbreak criteria, a public health investigator will be assigned to monitor the outbreak and will be available to provide site-specific COVID-19 prevention and control measures, infectious control recommendations and guidance as needed.
For assistance, contact communityoutbreak@ph.lacounty.gov or call 1-888-397-3993.
Note: Sites may be required to report suspected outbreaks to other agencies. Reporting to LAC DPH does not eliminate these additional reporting requirements.
