Rising COVID-19 rates in other states have prompted Chicago to restart a travel order.
The move comes after weeks of no travel restrictions and declining infections. The Chicago Department of Public Health announced Tuesday that unvaccinated travelers from Missouri and Arkansas have to either quarantine for 10 days or have a negative COVID-19 test. The restriction goes into effect Friday.
Both states have met Chicago's mark of at least 15 daily infections per 100,000 residents. Health officials say other states could be added if cases continue to rise, including Nevada, Louisiana, Utah and Florida.
Missouri is logging 203 cases per day per 100,000 people over the last week, according to the Centers for Disease Control and Prevention. Arkansas is seeing 237 cases per capita each day. Those numbers make them the two most infected states in the country.
