Dear Colleagues,

As respiratory viral season comes to a close, we want to share important updates regarding masking and flu vaccine programs across UCSF Health.

End of Respiratory Season & Flu Vaccine Programs
April 30, 2025, will mark the official end of the respiratory viral season and the conclusion of this year’s employee and inpatient flu vaccination programs.

End of UCSF Health-wide Masking Requirement
Effective May 1, 2025, the UCSF Health-wide health care personnel masking requirement will also end. This change aligns with public health guidance and reflects lower levels of community viral transmission. Staff may continue to wear a mask at any time based on personal preference or comfort.

Ongoing Masking for Certain Immunocompromised Patients
Protecting our most vulnerable patients remains a priority. Health care personnel will still be required to wear a mask when entering patient rooms in the following inpatient services:

• Adult Hematology, Blood & Marrow Transplant, and Cellular Therapy
• Adult Lung Transplant
• Pediatric Solid Organ Transplant (based on each service’s determination of immunosuppressed status)

To support implementation, we’ve developed clear workflows and Epic documentation, along with a standard sign that will be posted outside rooms where masking is required. This sign can also be used when a patient, caregiver, or care team requests that staff wear masks, regardless of service or provider order. More information is available here.

Thank you for your continued commitment to providing safe and compassionate care. If you have any questions, please reach out to your unit leadership or infection prevention team.

Sincerely,

Joshua Adler, MD
Chief Clinical Officer, UCSF Health
