Category 3 Clinical Research Density to Increase on February 1

January 28, 2021

Dear Research Community:

I am writing to announce that Category 3 clinical research density will increase from 12.5% to 25% on Monday, February 1, 2021. COVID-19 clinical research and clinical research determined to be essential to the health and/or well-being of the participant can continue without restriction.

The ability to increase Category 3 clinical research density at this time is due to the reduced rates of COVID-19 infection in the Bay Area counties, the reduced number of COVID-19 infections among UCSF employees, and the reduced number of COVID-19 hospitalizations in UCSF-affiliated hospitals. We also recognize the ongoing outstanding safety practices of our researchers, who continue to adhere to public health protocols requiring face coverings, physical distancing, completing the daily health screening before coming to campus, and practicing good hand hygiene.

Anyone concerned about adherence to public health protocols in their work environment or building should email EH&S at [email protected] or submit an anonymous employee hazard report online.

We greatly appreciate your commitment to safely conducting research during this pandemic. The precautions you take will help ensure that UCSF can continue to care for patients and protect the health and well-being of our faculty, staff, students, visitors, and the general public.
