Travel Guidelines for Suburban Cook County

Updated 9/14/2021

The Cook County Department of Public Health (CCDPH) weekly COVID-19 Travel Advisory now includes 48 states and three territories, as daily COVID case rates have come down in many states. Other states and territories, however, including some with the largest numbers of COVID cases, continue to experience high daily case rates. 

Connecticut and the District of Columbia have been taken off the Travel Advisory, as their daily COVID case rates have been under 15 per 100,000 residents for two consecutive weeks. States are removed from the Travel Advisory when they maintain a COVID case rate below 15 per 100,000 residents in two consecutive weeks. States and territories that could come off the Travel Advisory next week, as their daily case rates per 100,000 residents as of Tuesday are lower than 15, are California, Puerto Rico, and Vermont.

Unvaccinated travelers should be tested for COVID before and after travel.

CDC Recommendations For Unvaccinated People

If you are not fully vaccinated and must travel, take the following steps to protect yourself and others from COVID-19:

  • Before you travel:
    • Get tested with a viral test 1-3 days before your trip.
  • While you are traveling:
    • Wearing a mask over your nose and mouth is required on planes, buses, trains, and other forms of public transportation traveling into, within, or out of the United States and while indoors at U.S. transportation hubs such as airports and stations. Travelers are not required to wear a mask in outdoor areas of a conveyance (like on open deck areas of a ferry or the uncovered top deck of a bus). CDC recommends that travelers who are not fully vaccinated continue to wear a mask and maintain physical distance when traveling.
    • Avoid crowds and stay at least 6 feet/2 meters (about 2 arm lengths) from anyone who is not traveling with you.
    • Wash your hands often or use hand sanitizer (with at least 60% alcohol).
  • After you travel:
      • Get tested with a viral test 3-5 days after travel AND stay home and self-quarantine for a full 7 days after travel.
        • Even if you test negative, stay home and self-quarantine for the full 7 days.
        • If your test is positive, isolate yourself to protect others from getting infected.
      • If you don’t get tested, stay home and self-quarantine for 10 days after travel.
