According to the new guidelines, close contacts of these individuals should quarantine for seven to 10 days after exposure, which is a decrease from the initially recommended 14 days. These individuals can then end their quarantines after seven days if they receive a negative test, or 10 days if they do not get tested and “no symptoms have been reported during daily monitoring,” the CDC noted on its website.

It should be noted, however, that while the CDC has provided these alternative guidelines, they are still continuing to recommend quarantine for 14 days. 

“[The CDC] recognizes that any quarantine shorter than 14 days balances reduced burden against a small possibility of spreading the virus,” the health organization said on its website. “CDC will continue to evaluate new information and update recommendations as needed.”

Why Alternative Guidelines? 

While the CDC will continue to consider 14-day quarantines optimal, the organization recognizes that this quarantine length may prove difficult both physically and mentally for some individuals, as well as lead to financial difficulties. All of these factors, the CDC points out, are reasons that may contribute to a person’s ability to comply with the guidelines.

“Implementing quarantines can also pose additional burdens on public health systems and communities, especially during periods when new infections, and consequently the number of contacts needing to quarantine, is rapidly rising,” the CDC said on its website, adding that quarantine may also inhibit the ability to adequately contact trace if individuals become worried about the possibility of quarantining for a 14-day period.

“The change in guidelines was made in an effort to reduce the economic hardship endured by people who need to go back to work,” Soma Mandal, MD, a board-certified internist at Summit Medical Group in Berkeley Heights, New Jersey, tells Verywell. “The shorter quarantine period will hopefully enhance public compliance.” 

What Does ‘Close Contact’ Mean? 

In October, the CDC expanded its definition of close contact to include someone who has been within six feet of a person who has COVID-19 for a cumulative total of 15 minutes or more over a 24-hour period. Previously, this definition was limited to individuals who had 15 minutes of continuous exposure within six feet of an infected person.

Why the 14-Day Quarantine Guideline?

The CDC says the recommended 14-day quarantine after exposure was based on the initial estimates surrounding the COVID-19 incubation period.

“Quarantine’s importance grew after it was evident that persons are able to transmit SARS-CoV-2 before symptoms develop, and that a substantial portion of infected persons (likely somewhere between 20% to 40%) never develop symptomatic illness but can still transmit the virus,” the CDC says on its website. “In this context, quarantine is a critical measure to control transmission.”
