A Michigan resident who had been vacationing in Colorado has tested positive for bubonic plague.
The Michigan Department of Health says the unnamed resident is the state’s first ever recorded case of the disease. They said it’s likely the contracted the disease in Colorado because they visited an area “with reported plague activity.”
The confirmed infection is the 14th case of the life threatening disease this year. Three people have died from the plague this year: two in Colorado and one in Utah.
The Centers for Disease Control said that the plague has been reported almost exclusively in New Mexico, Arizona and Colorado since 1970. Only one infection has been confirmed to have taken place outside of those states, and that was in a lab environment.
Doctors say the disease is still extremely rare.
“Now, it’s very rare, especially in the U.S. There are only about 7 to 10 cases a year, but it still exists,” medical contributor Dr. Holly Phillips told “CBS This Morning.” “Think of rodents in very rural states — western states, southwest, ranches, farms — that’s likely what happened here.”
The number of overall infections this year is more than double the national average of seven cases.
