California health officials investigate another case of plague in Yosemite

California health officials are investigating another possible case of plague in a tourist from Georgia who fell ill after visiting Yosemite National Park, the second case in less than a month.

The California Department of Public Health on Tuesday said that “the presumptive positive case” of plague occurred on a patient who visited Yosemite, the Sierra National Forest and surrounding areas early this month.

The US Centers for Disease Control is testing the person, whose gender and age were not released, officials said.

US Public Health Service doctor Danielle Buttke, who is in Yosemite investigating the outbreak, says no new areas have been closed in the national park.

A child fell ill with the plague after camping with his family at Yosemite’s Crane Flat Campground in mid-July. The park reopened Crane Flat last week after treating it for four days with an insecticide.

Park officials closed the Tuolumne Meadows Campground from noon Monday through noon Friday last week so authorities can treat the area with a flea-killing insecticide after two squirrels died of plague in the area.

Campers had their reservations canceled at the 304-site campground so the insecticide can be sprayed into rodent “burrow holes,” the health department said.

Plague is carried by squirrels, chipmunks and other small rodents and is spread by their fleas, but transmission between people is rare.

“Although the presence of plague has been confirmed in wild rodents over the past two weeks at Crane Flat and Tuolumne Meadows campgrounds in Yosemite, the risk to human health remains low,” the health department said in a statement. “Action to protect human and wildlife health by closing and treating campgrounds was taken out of an abundance of caution.”

Officials say people should never feed squirrels and other small rodents. Campers should avoid setting up near rodent burrows, and hikers should wear long pants and use bug repellent to keep fleas away.
