Isolation: separates those infected with a contagious disease from people who are not infected.
Quarantine: restricts the movement of persons who were exposed to a contagious disease in case they become infected.
Duration of isolation or quarantine: To calculate the 5 or 10 days of isolation or quarantine, the date of either your positive test or the date that COVID-19 symptoms began is "Day 0." Then add 5 days to that date. For example, if your positive test date or the day symptoms began was January 1, add 5 days to that and your 5th day will be January 6.
Isolation and quarantine are proven public health interventions fundamental to reducing COVID-19 transmission. Isolation and quarantine processes are in place to slow the spread of the virus.
