According to the Illinois Department of Public Health (IDPH), in the period just prior to and just after Governor JB Pritzker issued his first stay-at-home order in March, houses of worship in Illinois experienced thirteen COVID-19 outbreaks, resulting in 88 cases.
Since then, Illinois has seen no such outbreaks until one was revealed last week. IDPH told me of a very recent church-related outbreak of 39 cases, including the pastor.
