Tularemia: review of eight cases of tick-borne infection and the epidemiology of the disease in Georgia.

In the period 1960 to 1979, 177 cases of tularemia occurred in residents of Georgia. A tick bite was the implicated source of exposure in eight cases (4.5%), whereas 91 cases (51.4%) were associated with direct contact with infected rabbits. In Georgia and other southeastern states, the epidemiology of human tularemia infection primarily involves rabbits. However, a diagnosis of tularemia should still be considered in this region in a febrile patient with or without a primary lesion or reported exposure to rabbits. A history of having been bitten by a tick may be the major clue in determining the diagnosis. A primary ulcerative lesion on the legs or in concealed body areas such as the axillary or intergluteal regions, is commonly the presenting sign in the patient with tick-borne tularemia.
