Hello does anybody know if you need a covet test to return back to the United States mainland? We are returning home our airport is Chicago O'Hare. We do not live in Chicago but I was just reading that the mayor of Chicago is requiring a test or a 10-day quarantine. However when you look on the CDC website it states that you do not need to have a test to return back to the mainland from Puerto Rico. Anybody have any advice about this?
