Plague Awareness

2018 PLAGUE SEASON

Ground squirrels in Idaho's desert sagebrush areas are known to be a source of plague. The highest risk for plague exposure to animals and humans occurs March through July. In early June 2018, an Elmore County child was confirmed to have plague. The child was treated and has recovered. It is most likely the child contracted plauge in Oregon, but an exact source was not found. In late June 2018, an Elmore County pet cat tested positive for plague. The cat was treated and is recovering. In mid-July, a feral cat died, most likely from plague.

Although no rodent die-offs have been reported so far in 2018, Idaho public health and wildlife officials remind people there is always potential for ground squirrels who reside in desert areas with sagebrush to carry plague, and urge anyone visiting these areas to take precautions to protect themselves and pets from plague.

In recent years, pets have become ill or died from contact with ground squirrels or their fleas — and put humans in danger of illness and death. In 2016, four cats from Elmore County and one from Ada County became infected with plague. Four of the five infected cats died.
