When to End Isolation

An important strategy for reducing transmission of COVID-19 is to identify those with infections and instruct them to isolate while they are infectious. It is also important to identify close contacts of infected individuals and provide guidance on how to take care of themselves and prevent transmission to others.   

Note that isolation guidelines are different for health care workers and those who work in clinical setting.

Day 0 = day of a positive test result (for Yale faculty, staff, and students) or the day that symptoms started (others)

Close Contacts

A close contact is someone who was less than 6 feet away from an infected person for a total of 15 minutes or more over a 24-hour period (for example, three separate 5-minute exposures for a total of 15 minutes). An infected person can spread the virus that causes COVID-19 starting 2 days before they have any symptoms (or, for people without symptoms, 2 days before the positive specimen collection date).

All household contacts, including roommates or suitemates are close contacts due to shared living spaces. 

With your help, your close contacts can be made aware of their exposure so they can take steps to test, mask, and monitor for symptoms. Yale faculty, staff and students may access our anonymous close contact notification form to notify close contacts who have yale.edu email addresses. (You must have a netID to access the form.) For all others see this guidance from the CDC
