PITTSBURG, Kan. — While the number of new COVID-19 cases in Crawford County decreased somewhat last week compared to the previous few weeks, public health officials said Tuesday that a recent increase in positive cases among children is a growing concern. There were 114 new cases last week, Public Health Officer Dr. Tim Stebbins told the Crawford County Commission on Tuesday, down from 185 the previous week and 186 the week before that. As of last Friday, 30 percent of newly identified positive cases were in the 0 to 17 age range, according to the county’s gating criteria, but the proportion of new cases that are being found in children is increasing, Stebbins said.
