Self-quarantine is a step up from self-monitoring because the person at risk of infection — even though the person still doesn't have symptoms ― had a higher chance of exposure. Quarantining means staying home and away from other people as much as possible for that 14-day period. People in this circumstance who don't live alone should do their best to retreat to their room or find a separate area in their home, and they shouldn't go out shopping, eating or socializing. A diagnosis of COVID-19 triggers isolation.
