On Sept. 22, the Chicago Department of Public Health (CDPH) took one state and one territoryCalifornia and Puerto Ricooff its weekly COVID-19 Travel Advisory, while Connecticut and the District of Columbia returned to the advisory.
The number of states and territories48 and three, respectivelyremain unchanged from last week.
States are removed from the Travel Advisory when they maintain a COVID case rate below 15 per 100,000 residents in two consecutive weeks. No other states or territories are at under 15 this week, so it will be at least two weeks until any new states come off the advisory.
Under the advisory, unvaccinated travelers should be tested for COVID before and after travel and should quarantine upon arrival in Chicago.
