COVID-19 Cases at the Lab

COVID-19 Cases in the Berkeley Lab Community

last updated September 18, 2020

Our highest priority is the health and well-being of our employees, 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 next steps.
