CHICAGO — The vast majority of the United States is considered low risk under Chicago’s travel advisory.

Just 4.4 percent of U.S. counties are considered medium or high risk under the advisory.

The city’s health department released an updated travel advisory Friday, noting the number of medium- and high-risk counties for COVID-19 has fallen since last week. The advisory is based on data and recommendations from the Centers for Disease Control and Prevention.

The CDC evaluates a county as low, medium or high risk depending on the number of new COVID-19 cases in that area, as well as what toll COVID-19 is placing on the area’s health care system.

All travelers should check the map so they know if they are going to an area where the COVID-19 risk is low, medium or high, according to the health department.

Here’s the city’s guidance:

Low-Risk Areas

Travelers do not need to take additional action, but they should follow standard guidance related to travel, according to the health department.

Medium-Risk Areas

Travelers should consider wearing a mask when indoors in public places.

High-Risk Areas

All travelers:

  • Wear a mask indoors in public place.
  • People 5 and older who are not fully vaccinated should avoid travel to high-risk counties.
  • All travelers should be fully vaccinated and boosted before traveling.
  • Travelers should watch themselves for symptoms of COVID-19. They should isolate and get tested if they develop symptoms.
  • Travelers should consider packing an at-home COVID-19 test so they can use it if they develop symptoms.
  • All travelers should bring a mask with them.

Unvaccinated travelers:

  • Unvaccinated Chicagoans who are 5 or older and go to a high-risk county should stay home and quarantine for five days after returning to Chicago.
  • Those travelers should also take a COVID-19 test three to five days after returning to Chicago. If it’s positive, they should stay home and follow CDC guidance.


• In Illinois, about 8.2 million people — or 64.48 percent of the state’s 12.7 million people — are fully vaccinated against COVID-19, according to state data.

• Across the state, 19,926 vaccine doses are being administered per day, based on a seven-day rolling average.

• Illinois and Chicago have administered at least 21,509,463 vaccine doses of the 26,089,945 provided to them.

• City data shows more than 1.8 million Chicagoans — or 68.7 percent of all residents — are fully vaccinated, and 77.2 percent of all Chicagoans have gotten at least one shot.

Everyone 5 and older is eligible to get vaccinated in Chicago.

COVID-19 vaccinations are free and do not require insurance. Anyone can call the city’s coronavirus hotline at 312-746-4835 to get more information on how and where to get vaccinated in their community.
