Loss of federal funding has led to COVID-19 testing site closures throughout Illinois, and the nation. Milder symptoms for those who are vaccinated and increased use of at-home rapid tests, which people rarely report to health authorities, means accurate COVID-19 data is increasingly hard to come by. 

After a year of delays, the Array of Things urban data sensor project is back on track and prepping to collect all sorts of information on Chicago's streets by early next year. Joining us to discuss the initiative are the project’s lead scientist Charlie Catlett and author Lori Andrews.
