On Wednesday, the Centers for Disease Control and Prevention 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.

Saline County Health Department Administrator Tara Brewer says the state of Missouri will decide in the next 24-hours if they will be following the same CDC guidelines.

According to the CDC, 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.

The revision marks a significant change from the CDC’s recommendations since the start of the pandemic earlier this year. While the agency says a 14-day quarantine remains the safest option, it acknowledged this length placed difficult demands on people.
