There are about 8.7 million species of animals on earth, most of which are harmless to humans. However, there are exceptions. Several animals take many people’s lives every year due to bites, poisoning, or diseases.
The most dangerous animals to humans in the world are:
Annual death toll: 1 million people
Our worst enemy, and the most dangerous animal globally, is the mosquito. These tiny leeches infect hundreds of millions of people with diseases every year, and about one million people die because of them. Therefore, mosquitoes kill the greatest number of people in the world.
One of the most dangerous mosquito-borne diseases is malaria, which kills over 400,000 people every year. Another mosquito-borne disease is dengue fever, affecting children in Asia and Latin America.
Number of deaths per year: approximately 100,000
Snakes are the most dangerous animals and reptiles on the planet; the WHO estimates that they kill between 81,000 and 138,000 people worldwide each year.
Annual deaths: 59,000
Man’s best friend is also on the list. However, this is not because they often bite their owners, but because they can spread the rabies virus (rabies). People can become infected if they come into contact with the saliva of an infected dog, such as through a bite.
According to WHO estimates, 99% of the approximately 59,000 deaths are caused by rabies transmitted by dogs. It can also be transmitted by a dog licking a wound.
Rabies is a deadly disease that is extremely difficult to treat. Therefore, most people who contract rabies die within two weeks.
4) Predatory Bugs
Annual number of deaths: 12,000
Predatory insects that sting and suck with their powerful noses are also life-threatening to humans. When it sucks blood from humans, it can transmit Chagas disease, a tropical parasitic disease, which kills 12,000 people a year, most of them children.
The course of Chagas disease begins with swelling and pain around the bite. After a few weeks, fever and malaise develop, followed by swelling of the lymph nodes, spleen, and liver. If untreated, the mortality rate is about 10%.
5) Tsetse Fly
Number of deaths per year: 3,500
In fifth place is the tsetse fly, one of the most miniature animals on the world’s most dangerous animals list.
People, especially those living in sub-Saharan Africa, are at risk of sleeping sickness transmitted by the tiny tsetse fly, a leech that prefers human blood.
The bite of this fly, if it is itself infected, can infect humans. Sleeping sickness, which causes headaches, fever, joint pain, itching, and other symptoms, kills 3,500 people every year.
As the disease progresses, people become unconscious, hence the name sleeping sickness. In East Africa, a more acute form of sleeping illness exists, and patients often die within a few weeks.
Number of deaths per year: 700
Tapeworms belong to the flatworm family and appear to be harmless. However, they have the unpleasant habit of living as parasites and do not spare humans.
When their eggs hatch in the bodies of humans and other mammals, the host develops a disease called cysticercosis, which kills 700 people every year.
Tapeworms can grow to be 4 to 10 meters long and can live up to 30 years in a host.
Annual death toll: 500
If the lion is the king of the savannah, the hippopotamus is the hothead of the savannah. You’d better give yourself plenty of room to walk around this temperamental tank.
Until recently, the hippopotamus was considered to be the most dangerous animal in Africa. About 500 people are killed by hippos every year, as they can capsize boats or crush them with their magnificent jaws. Its bite force is 826 kg/cm 2.
Note: the exact figures for the annual number of deaths could not be found. Numbers listed above should be considered as estimates.
