The most common cause of death was humans being infected by a dog with rabies. However, the National Canine Research Council reported that fatalities from dog maulings are extremely rare. In 2010, only 33 cases were reported of people being killed by a dog mauling. Snakes were ranked third for causing 50,000 human deaths a year. Of the roughly 3,000 snake species that exist in the world, about 600 are venomous, according to a study published in the PLOS Journal of Medicine. Humans were ranked as the second highest killer of the human race, averaging around 475,000 deaths caused by suicides and homicides.
