If you test positive on a rapid antigen or PCR test, you must self isolate (regardless of vaccination status). Initially, self isolation should be followed for five days. Following the fifth day, masks must be worn at all times when around other people. If unable to wear a mask, one must continue to self isolate until Day 10. One can stop wearing a mask or end self isolation prior to Day 10 if two negative test results are received within 48 hours of each other.
