The two outbreaks occurred in Schuyler and Adams counties.
At the summer camp, held in mid-June, the state health department said it was aware of “only a handful” of campers and staff who received COVID-19 vaccines. Masks were not required indoors, and the camp was not checking vaccination status, the agency said.
Most of the cases were among teens, IDPH Director Dr. Ngozi Ezike said in a statement.
“The perceived risk to children may seem small, but even a mild case of COVID-19 can cause long-term health issues,” she said. “Additionally, infected youth who may not experience severe illness can still spread the virus to others, including those who are too young to be vaccinated or those who don’t build the strong expected immune response to the vaccine.”
