Animal attacks are a common cause of either human injuries and fatalities worldwide. The large hippo, found in East Africa, occurs south of the Sahara, is often cited as the most dangerous large animal in the world, killing an estimated 500 people a year in Africa. Hippos are aggressive animals, and they have very sharp teeth. Male hippos can weigh up to 2,750kg.

9. Crocodile

Crocodiles are large aquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Crocodile’s physical traits allow it to be a successful predator.

Around 1,000 people each year are fatally attacked by crocodiles.  However, the deaths caused by crocodiles have been as high as 2,500 a year, according to Pravada.

8. Tapeworms

Tapeworms are flat, segmented worms that live in the intestines of some animals. Both Animals and Humans can become infected with these parasites when grazing in pastures or drinking contaminated water.

Tapeworms were the No. 9 killer, causing 2,000 human deaths per year. Tapeworms most commonly reside in the intestines, but some cases have been documented of tapeworms infesting the human brain.

7. “Ascaris” Giant Roundworm

Ascaris is an intestinal parasite of humans. It is the most common human worm infection. An estimated 807 million–1.2 billion people in the world are infected with Ascaris lumbricoides.

Ascaris parasites live in the intestine and Ascaris eggs are passed in the faeces of infected people and caused a disease called Ascariasis. Infections have no symptoms in more than 85% of cases, especially if the number of worms is small.

The Ascaris Roundworm is causing roughly 2,500 deaths per year. Around 10% of the world’s population in developing countries is infected with intestinal worms with a large percentage caused by Ascaris, according to the World Health Organization.

6. Freshwater Snails

Freshwater Snails can be fascinating inhabitants in an aquarium. However, the tiny parasitic snails that live in rivers and lakes across the world spread the disease called schistosomiasis, to humans.

The symptoms of the disease can include paralysis of the legs, vomiting blood and flu-like symptoms and cause roughly 10,000 human deaths per year. Lack of hygiene and certain play habits of school-aged children such as swimming or fishing in infested water make them especially vulnerable to infection.

5. “Reduviidae” Assassin Bug

Assassin bugs (or kissing bugs) get their names from their habit of biting humans on the face near the lips. They spread Chagas disease, which can be deadly. It is estimated that around 7 million people in Central and South America have Chagas disease.

It is estimated that 6.6 million people, mostly in Mexico, Central America and South America, have Chagas disease as of 2015.

4. Tsetse Fly

While tsetse flies resemble house flies, having a similar size ranging from 8 to 17 mm, two anatomical characteristics make them easily distinguishable while resting. When planning your African safari, you’ll want to learn a little about the biting tsetse flies and African sleeping sickness.

African Sleeping Sickness or Trypanosomiasis is a potentially fatal disease transmitted by the bite of tsetse flies and can be transmitted to man and animals. The freshwater snail, assassin bug, and Tsetse fly are all responsible for causing 10,000 human deaths per year.

3. Dogs

Dogs took fourth place by causing the deaths of 25,000 people annually around the world. 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.

2. Snakes

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.

1. Mosquito

The No. 1 killer of the human race has been labeled as the mosquito. Mosquitos carry several deadly diseases, including malaria.

Malaria is transmitted exclusively through the bites of Anopheles mosquitoes, and most deaths occur among children living in Africa, where a child dies every minute from malaria, according to the World Health Organization.
