Rabies virus, the gray fox, and the Alleghenian Biotic Region form a pathobiocenose; rabies in Virginia exists in a diffuse nidus, the Alleghenian Biotic Region. Physiographic features may serve as barriers or as passageways for epidemic spread of rabies. Epidemic spread is characterized by a radial pattern and a linear northeast-southwest pattern reflecting physiographic features. Incidence of rabies in the fox varies according to seasons. Present control efforts are generally ineffective; under certain conditions, population reduction for control of rabies may be detrimental instead of beneficial.
狂犬病病毒、灰狐和阿巴拉契亚生物区构成了一个病理生物群落；弗吉尼亚州的狂犬病存在于一个扩散的疫源地，即阿巴拉契亚生物区。自然地理特征可能成为狂犬病流行传播的障碍或通道。流行传播的特征是呈放射状模式和反映自然地理特征的东北 - 西南向线性模式。狐狸中狂犬病的发病率随季节变化。目前的防控措施总体上效果不佳；在某些情况下，为控制狂犬病而减少种群数量可能有害而非有益。
