Pasadena Public Health Department (PPHD) recommends anyone who is ill with respiratory symptoms or fever to stay home until they are fever-free for 24 hours and their symptoms have improved. Health officials also recommend that individuals with respiratory illnesses test repeatedly for COVID-19, with at least 24 hours between tests, if the initial test is negative but the individual remains symptomatic. Testing for COVID-19 with an at-home antigen test is encouraged to help minimize the spread of the virus. Please view the 8/19/2024 update for additional information.
While awaiting results, it is recommended that you minimize contact with others and wear a mask if you must go out into the community.

Caltech has implemented revised COVID-19 isolation guidelines in accordance with the California Department of Public Health (CDPH) and Pasadena Public Health Department (PPHD). The updated guidelines use a symptom-based approach for determining when isolation for COVID-19 is required.
Whether or not you are experiencing symptoms, you are instructed to stay home or isolate until 24 hours have passed. You may resume activities on campus with a mask if you meet the following criteria:
- fever-free for 24 hours without the use of fever-reducing medicines AND
- other symptoms are mild and improving or you remain asymptomatic.
You MUST wear a well-fitted (N95, KN95) mask around others through Day 10.
Isolate in Place
All undergraduate and graduate students living in Caltech housing may isolate in place. You may pick up meals from any campus venue while wearing a mask.
If you are too ill to pick up meals yourself, please ask a friend for assistance. Only in truly urgent situations should you contact your house RA or RLC for assistance with meals.
Medical Care
If your symptoms are not improving or you have any medical concerns, please call the student health center at (626) 395-6393 to schedule an appointment.
For after hours or weekend care, you may schedule a telehealth appointment with TimelyCare. This serves as a 24/7 virtual extension of our health and counseling services resources. It is free of charge for all enrolled students.
Read about self-care for respiratory symptoms.
Isolation Release
If your daily health surveys indicate that you have met the symptoms criteria, you will receive a release communication via your Student Health Portal.
A "close contact" is defined as someone who shared the same indoor airspace (e.g., small classrooms, labs, office) with a person diagnosed with COVID-19 for 15 minutes or more over a 24-hour period (does not have to be consecutive).
Guidelines for Post-Exposure:
- If you begin to feel sick with COVID-19 symptoms, please test immediately.
- If you do not have symptoms, are at a higher risk of severe COVID-19 infection, and would benefit from treatment, test within 5 days.
- If you do not have symptoms and have contact with people who are at higher risk for severe infection, it is recommended that you mask indoors when around them for 10 days. Consider testing within 5 days after the last exposure prior to contact with higher-risk people. Testing is available on campus via the surveillance testing program.
Note: Day 0 is the last day of your last contact/exposure with the confirmed case and Day 1 is the first full day after your last exposure.
