Use the search bar on the upper left, or sort by any column, to see a community's current coronavirus situation.  The World Health Organization considers a safe positivity rate to be 5.0% or under.  However, the State of Illinois considers a positivity rate under 8.0% to be acceptable, and the state often issues warnings to counties or regions when their rates reach 8.0% or above. Most all health organizations have real concerns when a positivity rate goes over 10%. The "7-Day Daily New Case Average per 100K" is a computation of the average daily new case count, over the most recent seven days, as a proportion of an area's population divided by 100,000. New-case averages under 10.0 are generally considered okay (though lower is always better).  Many states issue restrictions for travelers from areas where this figure is 10.0 or above. The City of Chicago often issues  restrictions for travelers from other states where this figure is 15.0 or above - requiring them to quarantine for 14 days upon arrival in the city. (The city has not, however, issued similar quarantine requirements for communities within Illinois -- or neighborhoods within the city -- when they have new-case rates of 15.0 or above.). NBC5 and Telemundo update this chart every evening.
