I am flying into Midway, then taking the orange line, I believe, to the stop nearest Amtrak station. I will be leaving on Amtrak about 4 hours after getting into the city. The Chicago website says that travelers must quarantine if their final destination is the city of Chicago. Since I am getting on the Amtrak and going to Seattle --essentially "transiting"-- does this mean I would need to quarantine? I appreciate any insight anyone can provide.
