The Centers for Disease Control and Prevention is set to shorten the recommended length of quarantine after exposure to someone who is positive for COVID-19, as the virus rages across the nation.

According to a senior administration official, the new guidelines will allow people who have come in contact to someone infected with the virus to resume normal activity after 10 days, or 7 days if they receive a negative test result. That’s down from the 14-day period recommended since the onset of the pandemic.

While the CDC had said the incubation period for the virus was thought to extend to 14 days, most individuals became infectious and developed symptoms between 4 and 5 days after exposure.
