Rare case of plague is confirmed in Oregon. Here's what to know about symptoms and how it spreads.

Health officials in Deschutes County, Oregon, confirmed a rare case of human plague in a local resident last week, marking the first reported case in the state since 2015. Officials said the individual was likely infected by their pet cat, which showed symptoms of the disease.

"All close contacts of the resident and their pet have been contacted and provided medication to prevent illness," Deschutes County Health Officer Dr. Richard Fawcett said in a news release Wednesday. 

No additional plague cases have emerged during their investigation, said officials in the mostly rural county in central Oregon.
