Gray Wolf

Recorded incidences of rabid wolves in Eurasia go far back as the 13th century. The number of cases of rabid wolves are however low when compared to other species. Wolves do not serve as primary reservoirs of the disease, but can catch it from other animals such as dogs, jackals and foxes. Cases of rabies in wolves are very rare in North America, though numerous in the eastern Mediterranean, Middle East and Central Asia. Wolves apparently develop the "furious" phase of rabies to a very high degree. This, coupled with their size and strength, make rabid wolves perhaps the most dangerous of rabid animals, with bites from rabid wolves being 15 times more dangerous than those of rabid dogs. Rabid wolves usually act alone, travelling large distances and often biting large numbers of people and domestic animals. Most rabid wolf attacks occur in the spring and autumn periods. Unlike with predatory attacks, the victims of rabid wolves are not eaten, and the attack generally only lasts a day. Also, the victims are chosen at random, though the majority of cases involve adult men.
Predatory attacks usually involve single wolves or packs that learn to exploit humans as prey. Such attacks may be preceded by a long period of habituation, in which wolves gradually lose their fear of humans. The victims are generally attacked in a sustained manner around the neck and face, and are then dragged off and consumed, unless the wolves are disturbed. Such attacks tend to cluster in time and space until the offending animals are killed. Predatory attacks can occur at any time of the year, with a peak in the June–August period, when the chances of people entering forested areas (for livestock grazing or berry and mushroom picking) increase, though cases of non-rabid wolf attacks in winter have been recorded in Belarus, the Kirovsk and Irkutsk districts, Karelia and Ukraine. Also, wolves with pups experience greater food stresses during this period. The majority of victims of predatory wolf attacks are children under the age of 18 and, in the rare cases where adults are killed, the victims are almost always women. Non-rabid wolves are able to distinguish between armed and unarmed people, and will typically avoid investigating people who display self confident demeanors typical of being armed.
Wolves may react aggressively in self defense, though such attacks are mostly limited to quick bites on extremities, and the attacks are not pressed.
