Animal attacks are a common cause of either human fatalities or injuries. The frequency of animal attacks varies with geographical location. In the United States, a person is more likely to be killed by a domesticated dog than they are to die from being hit by lightning.
Animal attacks have been identified as a major public health problem. In 1997 it was estimated that up to 2 million animal bites occur each year in the United States. Injuries caused by animal attacks result in thousands of fatalities worldwide every year. All causes of death are reported to the Centers for Disease Control and Prevention each year. Medical injury codes are used to identify specific cases. The World Health Organization uses identical coding, though it is unclear whether all countries keep track of fatalities caused by animals.
Bite injuries are often the consequences of an animal attack, including those instances when a human attacks another human. Human bites are the third most frequent type of bite after dog and cat bites.Dog bites are commonplace, with children the most commonly bitten and the face the most common target. In 1936, amputation was required in one third of cases in which treatment was delayed for 24 hours or longer.
Animal bites are the most common form of injury from animal attacks. The US estimated annual count of animal bites is 250,000 human bites, 1 to 2 million dog bites, 400,000 cat bites, and 45,000 bites from snakes. Bites from skunks, horses, squirrels, rats, rabbits, pigs, and monkeys may be up to 1 percent of bite injuries. Pet ferrets attacks that were unprovoked have caused serious facial injuries. Non-domesticated animals though assumed to be more common especially as a cause of rabies infection, make up less than one percent of reported bite wounds. When a person is bitten, it is more likely to occur on the right arm, most likely due to defensive reactions when the victims uses her or his dominant arm. Estimates are that three quarters of bites are located on the arms or legs of humans. Bites to the face of humans constitutes only 10 percent of the total. Two thirds of bite injuries in humans are suffered by children aged ten and younger. The subsequent treatment for those who have been attacked (if they survive) depends on the injuries. Though trauma may be addressed first, subsequent infections are also treated with appropriate antibiotics.
