Yosemite National Park officials announced Friday that they are temporarily closing a popular campsite after two squirrels were found dead with the plague.

Tuolumne Meadows Campground, a 304-site campground within Yosemite, will close starting from noon on Monday until noon on Friday. During this time, authorities will be treating the area with flea-killing insecticide, according to CBS News.

Treating the area is being described as an "extremely precautionary public health measure," park officials have said, The Los Angeles Times reported.

The campground closure comes one week after a child was diagnosed with the plague at Crane Flat Campground, 40 miles from where the infected squirrels were found, according to The Telegraph. This was the first reported case of the disease in humans in California since 2006.

Health department officials have commented on the recent cases, saying that, "although the presence of plague has been confirmed at Crane Flat and Tuolumne Meadows campgrounds, the risk to human health remains low."

Crane Flat Campground was closed for four nights in order for officials to perform flea treatments, according to the LA Times.

Two people have died from the plague in Colorado this year, according to the Telegraph. Since 1970, 42 people in California have contracted the disease, nine of them fatally.
