Bubonic plague has emerged in Michigan - part of a troubling national trend that has seen annual cases of the disease double.
While this is Michigan's first reported case of the plague, ABC News is reporting that the victim had just returned from a trip to on of the disease's known hot spots - the American West:
"The Michigan Department of Health and Human Services said Monday that a Marquette County resident is recovering after being treated for the bubonic plague. The resident recently returned from an area of Colorado that had reported plague activity. That region is experiencing an increase in plague cases, four of which have been fatal. Officials don't know the cause."
The Centers for Disease Control says most human cases in the United States occur in two western regions:
- Northern New Mexico, northern Arizona, and southern Colorado
- California, southern Oregon, and far western Nevada
The California Department of Public Health has investigated two recent cases of human plague. In the latest incident , the patient had been vacationing in Yosemite National Park (Yosemite), the Sierra National Forest and surrounding areas in California in early August.
In California, plague-infected animals are most likely to be found in the foothills and mountains and to a lesser extent, along the coast. This month, a squirrel near Lake Tahoe tested positive for plague. In 2014, non-human plague activity was detected in animals in seven counties: El Dorado, Mariposa, Modoc, Plumas, San Diego, Santa Barbara, and Sierra.
This is map from the California Department of Public Health displays location-specific and county-level information of wild rodent testing since 1984.
- Never feed squirrels, chipmunks or other rodents and never touch sick or dead rodents.
- Avoid walking or camping near rodent burrows.
- Wear long pants tucked into socks or boot tops to reduce exposure to fleas.
- Spray insect repellent containing DEET on socks and pant cuffs to reduce exposure to fleas.
- Keep wild rodents out of homes, trailers, and outbuildings and away from pets.
