Forget bird flu - watch out for the ground squirrels


Los Angeles County health officials have confirmed a case of bubonic plague in an adult woman. This is the first human case of plague in a Los Angeles County resident since 1984.

The affected individual resides in the Country Club Park area of the city of Los Angeles. The woman, who came down with symptoms one week ago and remains hospitalized, may have been exposed to fleas in the area around her home. The investigation is continuing. "Bubonic plague is not usually transmissible from person to person," says Jonathan Fielding, M.D., M.P.H, Director of Public Health and Health Officer, Los Angeles County.

"Fortunately, human plague infection is rare in urban environments, and this single case should not be a cause for alarm in the area where it occurred." "Plague is characterized by fever, muscle aches, nausea, headache, sore throat, fatigue, and swollen, tender lymph nodes associated with the arm or leg that has flea bites and is treatable with antibiotics," added Dr. Roshan Reporter of the Acute Communicable Disease Control Program. "The disease often causes illness serious enough to warrant hospitalization, but if treated is rarely fatal."

Bubonic plague is endemic among ground squirrels around Tehachapi, Lake Isabella, Frazier Park, and in the Angeles National Forest between Los Angeles and Antelope Valley. Los Angeles County health officials annually send out warnings for campers, hikers and residents in those areas to take precautions against the disease mainly by avoiding ground squirrels and their fleas.
