Your Guide to COVID-19 & Respiratory Illnesses

November 10, 2025

Recommendations

Thank you for your continued cooperation and support. Caltech follows guidance from Pasadena Public Health for requirements related to respiratory illnesses and other communicable diseases. We also comply with all applicable OSHA workplace regulations.

Student Wellness Services (SWS) Contact Tracing remains available to assist with individual cases, and to monitor and support response efforts in the event of clusters or outbreaks. We encourage voluntary reporting to help maintain a healthy campus environment—supporting our community's ability to sustain in-person learning and research while addressing ongoing and emerging public health concerns.

Reminders:

  • Report your illness using the COVID-19 app: All faculty, staff, post-doctoral scholars, and students are encouraged to report positive test results via the COVID-19 reporting app.
  • Vaccination/Booster – Effective June 19, 2023: Caltech has ended its current COVID-19 vaccination requirement for Caltech employees and students. Per the Pasadena Public Health Department, it is still recommended to stay up to date on your vaccines to help protect yourself this respiratory illness season.
  • Masking – Effective April 17, 2023: Masks are voluntary in indoor spaces unless otherwise indicated. Free masks are still available for pickup at the bookstore with your Caltech ID.
  • For employees, if you are unable to work due to illness, please notify your supervisor as soon as possible. You may also coordinate with your supervisor to arrange remote work, if appropriate for your job duties. If you anticipate being out for more than five consecutive workdays, please contact the Disability and Leave Administration Unit (DLAU) at [email protected] or call (626) 395-3092. As per OSHA regulations, all workplace exposures are reported on the COVID-19 Dashboard.
