Research by the University of Washington, released Thursday, predicted the peak will hit Illinois around April 16. Another team of scientists, who advocate for social distancing under the name CovidActNow, have forecast that a wave may not hit until at least May 14, and as late as May 26, depending on how well people avoid spreading the virus. The better residents are at social distancing, the longer it will take for the wave to hit and the milder the wave will be, according to the forecast.
