(CNN) -- Indiana and Montana have joined the growing list of states with confirmed cases of Enterovirus D68, health officials say.

Four children in Lake County were sickened by Enterovirus D68 and were treated at University of Chicago Hospital, according to a press release from the Indiana Department of Health; all four have since been discharged from the hospital. Lake County is in the northwest corner of the state.

Montana has one confirmed case of Enterovirus D68, says Jon Ebelt, a spokesman for the state's public health department. "A specimen sent to the CDC from a child under the age of 10 has tested positive for the particular strain of enterovirus," he told CNN.

Enteroviruses are very common, especially in the fall and winter months. The Centers for Disease Control and Prevention estimates 10 to 15 million infections occur in the United States each year. But this type of enterovirus -- Enterovirus D68 -- appears to be exacerbating breathing problems in children with asthma.
