About Potential COVID-19 Exposure in the Workplace

A “Potential COVID-19 exposure” means sharing the same airspace as a COVID-19 case for a cumulative total of 15 minutes or more over a 24-hour period during the COVID-19 case’s infectious period, regardless of the use of face coverings. 

“Infectious period” means the following time period, unless otherwise defined by CDPH regulation or order, in which case the CDPH definition shall apply:

(A) For COVID-19 cases who develop COVID-19 symptoms, from two days before the date of symptom onset until:

(1) Ten days have passed after symptoms first appeared, or through day five if testing negative on day five or later; and

(2) Twenty-four hours have passed with no fever, without the use of fever-reducing medications, and symptoms have improved.

(B) For COVID-19 cases who never develop COVID-19 symptoms, from two days before the positive specimen collection date through 10 days (or through day five if testing negative on day five or later) after the date on which the specimen for their first positive test for COVID-19 was collected.

Please note that there can be reporting delays between when an individual is tested and found to be positive, and when the corresponding potential exposure locations are reflected here. The Potential Workplace Exposure dates reflect either the date a person developed symptoms, or in the absence of symptoms, the date of a positive test result. This date is more effective for personal exposure consideration as it defines the infectious period.
