COVID Cases at the Lab

COVID Cases in the Berkeley Lab Community 

last updated April 12, 2024

Our highest priority is the health and well-being of our workers, their families, and our communities. The Lab’s COVID-19 protocols are designed to maintain a very low exposure risk for those working on site, taking into account that occasionally, people who are unaware they are infected with COVID-19 will enter a Lab facility. 

If you are symptomatic, think you may have been exposed to someone with COVID-19, test positive for COVID-19, or have supervisory responsibility for someone who may be infected with COVID-19, please contact Health Services immediately at 510-486-6266 for information on the next steps. ALL CALLS TO HEALTH SERVICES ARE CONFIDENTIAL.

Note: The Lab is required to report all known COVID-19 cases to the Department of Energy, no matter if workers are on site or not. Therefore, all COVID-19 cases in the Lab population should be reported to Health Services. Even those individuals teleworking or those who have not been on a Berkeley Lab site in the 14 days prior to the onset of symptoms should report their results to Health Services. 

In addition, all are welcome to contact Health Services with questions or concerns.  Individual patient care information is kept confidential, and only Health Services staff are informed of any medical concerns. Health Services is mandated to report the number of positive cases to the City of Berkeley Public Health Department and Lab management.
