IDAHO FALLS, Idaho (AP) — Eastern Idaho health officials say four children have been hospitalized due to a respiratory virus.

Officials tell KIFI-TV that the children on Wednesday are being treated at the Eastern Idaho Regional Medical Center. Hundreds of children in more than 10 states have been sickened by a severe respiratory illness that public health officials say may be caused by an uncommon virus similar to the germ that causes the common cold.

The four cases in eastern Idaho are the first reported in the state. Hospital officials say the children have symptoms consistent with enterovirus 68. Health experts say the virus can cause mild coldlike symptoms but that this summer's cases are unusually severe and include serious breathing problems.
