Los Angeles Department of Public Health, as well as the California Department of Public Health, has updated COVID isolation requirements and OSHA has aligned so that we treat adult and student COVID isolation the same.  There are two scenarios listed below.

Individuals with COVID-19 with symptoms:  Individuals who have a confirmed case of COVID-19 and are experiencing symptoms shall stay home away from others until fever-free for 24 hours without using fever-reducing medication AND other symptoms are mild and improving.  Masks are required to leave isolation before 10 days from when symptoms began or the date of their first positive test, when around other people.  You can remove your mask sooner if you have two sequential negative tests at least one day apart.

Individuals with COVID-19 without symptoms:  Individuals who have a confirmed case of COVID-19 and are not experiencing symptoms are not required to isolate provided they wear a well-fitting, high-quality respiratory mask whenever around other people.  You can remove your mask sooner if you have two sequential negative tests at least one day apart.
