You can end quarantine 14 days after your last close contact with a person who has COVID-19.
Even if you get tested for COVID-19, have no symptoms, and have a negative test, you should remain in quarantine for the entire 14 days. COVID-19 symptoms can appear anywhere from 2 to 14 days after exposure.
If, during your quarantine, you have close contact with a person with COVID-19, you need to begin your quarantine over from day 1 and remain there until 14 days have passed with no contact.
If you are caring for someone with COVID-19 and can’t avoid close contact, you can end your quarantine 14 days after that person has been able to end home isolation.
