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.

Please note that test results from UCLA SwabSEQ or SWS are not reported identifying any individual's results. All faculty,staff and students are encouraged to report positive test results via the COVID-19 reporting app.
