According to the California Department of Health, a Georgia native is believed to have contracted the disease during a recent vacation. Areas that the tourist visited are currently being examined by the National Forest Service and the Center for Disease Control.
Less than a month ago, a child from Los Angeles Country became ill and was hospitalized after visiting Yosemite National Park. That child is recovering, and no other members of the camping party have reported any related symptoms, according to authorities.
Prior to this year, the last case of human plague reported in the Yosemite Valley was in 1959.
Plague is an infectious bacterial disease that is carried by squirrels, chipmunks and other wild rodents and their fleas. When an infected rodent becomes sick and dies, its fleas can carry the infection to other warm-blooded animals or humans.
Early symptoms of plague include high fever, chills, nausea, weakness and swollen lymph nodes in the neck, armpit or groin. People who develop these symptoms should seek immediate medical attention and notify their health care provider that they have been camping or out in the wilderness and have been exposed to rodents and fleas. Plague is treatable in its early stages with prompt diagnosis and proper antibiotic treatment.
Since 1970, 42 human cases of plague have been confirmed in California, of which nine were fatal.
