The symptoms of this illness have now been separated into three
stages. If caught before the end of the first stage, the illness is
usually easily treated by antibiotics. In general, a high fever
combined with stiffness or arthritic symptoms (in both people and
animals) can indicate Lyme disease. The next two stages represent
greater systematic involvement and include the nervous system and the
heart. If still untreated, the third stage involves the
musculoskeletal system. The erythema migrans (small round rash at the
site of the bite) is the best early sign of a problem. Unfortunately,
the tick that bites is usually a larva or nymph and so is seldom seen.
The resulting rash is seen in approximately 80% of adults but only
about 50% of children. It is imperative that it be diagnosed early
since the more severe symptoms can begin quickly. Treatment consists
of several broad spectrum antibiotics -- including tetracycline,
penicillin, and erythromycin. This is effective, especially in the
early stages. Consult with your veterinarian or doctor.
