Plague in Idaho squirrels prompts health warning

Boise, Idaho • Ground squirrels south of Boise have tested positive for plague, and humans and pets should avoid the area, Idaho health officials say.

The bacterial disease can be spread by the bites of fleas or by direct contact with infected animals, the Idaho Department of Health and Welfare said in a statement Friday.

"We would probably advise people not to go out in that area," said Tom Shanahan, spokesman for the agency. "If you go out there, you need to take precautions."

Officials said that includes insect repellent and staying away from dead animals. Pets should be protected with flea-repellent products and not be allowed to roam free, which increases the chances of a pet rolling on a dead ground squirrel or picking it up.

Mike Keckler of Idaho Fish and Game said the agency investigated earlier this week after receiving reports of dead ground squirrels and found 24 die-off sites. Seven dead squirrels were sent overnight to the U.S. Centers for Disease Control and Prevention, he said, and researchers confirmed on Friday morning to Idaho officials that plague caused the deaths.
