CDC recognizes that any quarantine shorter than 14 days balances reduced burden against a small possibility of increasing the spread of the virus. However, with the addition of diagnostic testing of a specimen collected up to 48 hours before Day 10, the estimated post-quarantine transmission risk was reduced to 0.3% (range 0.0%-2.4%) for RT-PCR testing, and 1.1% (0.1%-9.5%) for antigen testing with a test that had a diagnostic sensitivity of 70%. 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, are rapidly rising. The CDC is working on a big change to coronavirus quarantine guidelines for people who have been in contact with infected individuals. Modelers from the University of Utah School of Medicine estimated the post-quarantine transmission risk accordingly (unpublished data).

The variability of SARS-CoV-2 transmission observed to-date indicates that while a shorter quarantine  substantially reduces secondary transmission risk, there may be settings (e.g., with high contact rates) where even a  small risk of post-quarantine transmission could still result in substantial secondary clusters. What's the difference between quarantine and isolation? Your local public health authorities make the final decisions about how long quarantine should last, based on local conditions and needs. 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%1) never develop symptomatic illness but can still transmit the virus.
