The Chicago Department of Public Health has not made any changes to its COVID-19 Travel Advisory since last week when it took California and Puerto Rico off the advisory because average daily new cases there fell below 15 per 100,000 residents, officials announced Tuesday. Public health officials added that Connecticut’s daily case rate is under 10 per 100,000 this week, and if that rate stays below 15 per 100,000 residents, it could come off the city’s advisory next week.
