The Centers for Disease Control and Prevention has revised its guidelines for people who may have been exposed to the coronavirus. Now, instead of the standard 14-day quarantine it has been recommending, the CDC says that potential exposure warrants a quarantine of 10 or seven days, depending on one's test results and symptoms.

If individuals do not develop symptoms, they need only quarantine for 10 days; if they test negative, that period can be reduced to just one week.
