“In August, we estimated there could be 39,000 COVID-19 cases in September among school-aged kids in Utah. We were way off. The actual number was 9,957, well below our projection,” the Utah Department of Health said in a recent tweet.

Officials with the department acknowledged that public health modeling is “complex,” as it attempts to predict behavior based on past measures.
