CDC’s new COVID-19 Quarantine and Isolation (Q&I) Calculator takes the stress out of figuring when, and for how long, people with COVID-19 and close contacts need to stay home, get tested, and wear a well-fitting mask. Developed in response to requests from partners and the public, the calculator provides important information about what precautions people with COVID-19 and their close contacts can take to protect loved ones and slow the spread of COVID-19 in their communities. This online, mobile-friendly calculator provides an easy-to-use way to help people follow CDC’s quarantine and isolation guidance and get customized information to address their unique situation.

The tool is available in several languages.
