B. Contact Tracing and Employee / Employers


  • Yes, if the employee is an OC resident.
  • No, if the employee is a not an OC resident. The employee's county health department of residence will manage the case. The HCA may assist another county in their investigation when it involves an OC employer.

The HCA has established a Case and Contact Investigator (CCI) team. More information on the CCI team may be found at the following link: https://occovid19.ochealthinfo.com/sites/virus/files/2020-05/COVID-19_Contact_Tracing_v03.pdf


Privacy laws require maintaining an employee's confidentiality. The HCA will only notify the employer if there are exposures in the workplace and an investigation is necessary.


Refer to State guidance for the relevant sector here: https://covid19.ca.gov/industry-guidance/. Generally, employers do not need to report individual cases to health department (the HCA) as all laboratories are required to report results; however, in some industry types — such as schools — the employer is required to report cases. For additional information, please call our Health Referral Line from Monday - Friday from 8 a.m. - 5 p.m. at 1(800) 564-8448.


State guidance for most sectors requires employers to have the ability to do contact tracing within the workplace; however, the employer is not responsible for contact tracing outside of the workplace. The HCA’s Case and Contact Investigator team will perform contact tracing if the employee is an OC resident or if assistance is requested from another County for a non-OC resident.

The Centers for Disease Control and Prevention has available FAQs for employers with suspected or confirmed COVID-19 employees, which are available at the following link: https://www.cdc.gov/coronavirus/2019-ncov/community/general-business-faq.html#Suspected-or-Confirmed-Cases-of-COVID-19-in-the-Workplace

Please know the HCA does not perform case investigation and contact tracing based on serology (antibody) test results. Serology results alone are NOT used to diagnose a current COVID-19 infection.

If you have additional questions, please call the HCA's Health Referral Line Monday - Friday from 8 a.m. - 5 p.m. at (800) 564-8448.
