When notified of a case at your worksite
When you learn an employee has tested positive, perform an investigation, make a list of contacts, and report results to Berkeley Public Health.
Identify who may have been exposed
When an employee tests positive for COVID-19, you’ll need to perform an investigation to identify anyone who may have been exposed.
Review the employee’s schedule and work location to determine who they have had close contact with during their infectious period. For the purposes of the investigation:
- Close contacts: a “close contact” is anyone who was within 6 feet of the infected employee for 15 minutes or more over a 24-hour period.
- Exposure dates
- If the employee has symptoms of COVID-19, the infectious period begins 2 days before symptoms first appeared
- If an employee tested positive without symptoms, review their interactions for their last two days at the worksite
When conducting your investigation, remember to review time spent in shared spaces, such as break rooms, and contact with non-employees, such as customers or vendors.
Report to Public Health
Report all exposures via the Shared Portal for Outbreak Tracing (SPOT). Be sure to select Berkeley as the Local Health Jurisdiction.
Once entered someone from City of Berkeley will respond via email or phone within 1 business day.
Notify any employees you have identified as potentially being exposed, anyone who is symptomatic or unvaccinated should be instructed to get tested and to quarantine at home for 10 days after the last exposure to the infected employee. The City has prepared a template you can use for this letter:Document
Do not disclose the name of the employee who has tested positive.
Provide testing opportunities
You are required by Cal/OSHA to offer COVID-19 testing during working hours to employees who had a potential COVID-19 exposure. This testing must be available to employees at no cost.
Please note that a negative test is not clearance to return to work. Employees should only return to work after they have completed their 10 day quarantine.
Outbreaks (3 or more cases)
If you learn of 3 or more confirmed cases among employees, contact us immediately and arrange for testing for all employees.
Report all exposures via the Shared Portal for Outbreak Tracing (SPOT) then call (510) 981-5292 or email firstname.lastname@example.org with the subject line “Berkeley Worksite Exposure - possible outbreak.”
Berkeley Public Health will ask for the following information. Please have as much of this available as possible when you report - but do not delay reporting an outbreak if you are missing any of these documents:
- Layout of your worksite and the location where the infected employee works
- List of employees exposed and their vaccination status
A Berkeley Public Health investigator will contact you and provide guidance on next steps, including possible site closure.
Refer to Cal/OSHA for additional recommendations and guidance.
