When should I quarantine or isolate?

Quarantine occurs BEFORE a person becomes sick or tests positive.  Quarantine (see below) if you have been in close contact (within 6 feet of someone for a cumulative total of 15 minutes or more over a 24-hour period) with someone who has COVID-19.

Isolation occurs AFTER a person becomes sick or tests positive, regardless of vaccination status. A person with COVID-19 is required to stay home, not go to work, and avoid other people, staying isolated in their own bedroom and using their own bathroom as much as possible.

If You Must Travel During the Pandemic

COVID-19 doesn’t take a vacation. Travel can increase your chances of getting and spreading COVID-19. The CDC recommends delaying travel until you are fully vaccinated. Review the local regulations and pre-travel requirements (negative test for entry, complete vaccination) before traveling.
