Travel Guidance

Travel Guidelines for Suburban Cook County


Updated 11/30/2021
Based on data as of 11/29/2021

The Cook County Department of Public Health (CCDPH) removed two states and Guam from its weekly COVID-19 Travel Advisory today. No new states were added to the advisory, which now stands at 38 states. California, Guam, and North Carolina were removed from the advisory, as their daily COVID case rates have been below 15 per 100,000 residents for two consecutive weeks.

As of Tuesday, every state or territory except for Alabama, California, D.C., Florida, Georgia, Guam, Hawaii, Louisiana, Mississippi, North Carolina, Puerto Rico, South Carolina, Tennessee, Texas, and the Virgin Islands are on the Travel Advisory.

Maryland, Nevada, Oklahoma, Oregon, and Washington, all with daily case rates under 15, could be removed from the travel advisory next week, if their daily COVID case rates remain below 15 per 100,000 residents for a second consecutive week.

Though some states are coming off the Advisory this week – and possibly next week – most Midwest states remain firmly on it. The three states with the highest daily rates of COVID per 100,000 residents in the U.S. are Minnesota, Michigan, and Wisconsin.

The U.S. average daily case rate per 100,000 residents is 21.7, (down from 27.3 last week). Illinois’ daily case rate currently is 23.7 (31.9 last week).

School-aged Children After Domestic Travel
School-aged children do NOT have to quarantine after returning from domestic travel. They should continue to attend school in-person. However, they should get tested 3-5 days after returning from their trip and should monitor for symptoms of COVID-19 for 14 days.

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.
