Another set of tests have determined fleas found in Doney Park are carrying the plague. Coconino County health officials say fleas were collected near prairie dog burrows northeast of Flagstaff. Last week, fleas tested in the Red Lake area northeast of Williams also tested positive for the disease. The disease can be transmitted to humans and other animals by the bite of an infected flea or by direct contact with an infected animal. Symptoms of plague include: fever, chills, headache, weakness, muscle pain and swollen lymph glands. If anyone has been exposed to rodents or prairie dogs and has the symptoms, see your doctor immediately.
