POCATELLO, Idaho (KIFI) — Health officials are reporting five probable measles cases in Canyon County, all within a single unvaccinated household, as they work to prevent the virus from spreading in local schools and the wider community. “We have had five probable cases of measles here in Canyon County,” she said. Eastern Idaho has reported measles cases this year from Madison County; however, due to the time it takes for symptoms to fully manifest, they have not yet been confirmed. Ian Troesoyer, a nurse practitioner and epidemiologist for Southeastern Idaho Public Health, said Idaho is at a crossroads. “We are worried about measles cases in our own state and from adjoining states coming into our district,” he said.
