Wild Animals That Kill


What wild animals are most likely to kill a human?

It's not lions, tiger, or bears.  The seven most dangerous wild animals are:

  • Scorpions envenomate around 1.5 million people a year and kill about 3,000 people a year.

  • Tsetse Flies infect people with a disease called African trypanosomiasis, also known as sleeping sickness. About 60-70 million people in 20 nations are at various levels of risk from Tsetse flie sleeping sickness, and the DALY index estimate (disability-adjusted life years, which measures the length of life lost to premature death and the length of a life lived with a handicap) is that sleeping illness causes 2 million DALYs each year, or about 10,000 direct deaths per year.

  • Assassin bugs, also known as Kissing bugs, are attracted to lights in homes where they bite people and spread the parasite that causes Chagas disease which kills about 10,000 people every year.

  • Feral dogs can pass rabies and cause fatal bites and maulings. The World Health Organization estimated that 59,000 people died from rabies in 2018, with about 60 percent of deaths in Asia and 36 percent of deaths in Africa, and with about half of all rabies infections (30,000) caused by  dog bites. In addition, every year, tens of millions of people across the globe are bitten by dogs, with thousands -- mostly children and the very old -- succumbing from their wounds.

  • Freshwater snails have infected about 236 million people with a parasitic worm that causes schistosomiasis, a disease which kills about about 20,000 people a year.

  • Snakes bite about 5.4 million people a year and about 2.7 million are envenomated (not all venomous snakes actually envenomate when striking). Between 50,000 and 100,000 people die each year because of snake bites, and around three times as many amputations and other permanent disabilities are caused by snakebites annually.

  • Mosquitoes kill between 700,000 and a million people a year through diseases that range from malaria to filariasis and arboviral diseases like yellow fever, Chikungunya, West Nile, encephalitis, dengue fever, and Zika.

What are the most dangerous wild animals in the US?   Deer (due to vehicle impact), farm animals (horses, cows, pigs), anaphylaxis from bees, wasps, or hornet stings, and dog attacks.
