Updated General Public Isolation & Quarantine Requirements

The latest guidance from the CDC recommends that people who test positive for COVID-19 should stay home and isolate alone and away from others for at least five days after testing positive, reduced from a 10-day isolation.

If you do not have symptoms five days after your positive test, you can leave isolation, but should continue to wear a well-fitting mask around others for an additional five days. If you still have symptoms after isolating for five days, you should stay home until symptoms resolve.

The CDC’s recommendations are based on the latest scientific data on COVID-19 transmission. Data show that people with COVID-19 are most contagious one to two days prior to experiencing symptoms and two to three days after the onset of symptoms. The new guidance also recognizes the added degree of protection provided by vaccination and a booster dose.


Isolation & Quarantine Requirements for other settings

  • People who live or work in in a high-risk setting, including long-term care, correctional and healthcare settings, contact your employer and/or public health for guidance.
  • People who have children in early childhood/daycares/pre-school or who have students in K-12 schools should contact their schools and/or public health for guidance.
