Mosquitoes and Humans Named World's Deadliest Creatures as Sharks Miss Top Ten
A comprehensive data analysis reveals mosquitoes as the deadliest non-human threat, killing over 750,000 people annually. Humans rank second, while sharks cause only a handful of deaths.
If you were asked to name the animal most dangerous to humans, you would likely think of sharks. However, annual mortality statistics show that sharks do not even rank among the top ten. In fact, they sit around 20th place, causing only about six deaths per year worldwide.
The Tiny Giants of Mortality
According to data compiled by Our World in Data, the absolute deadliest creature on Earth is the mosquito. It is estimated that over 750,000 people die each year due to mosquitoes—not from the insects themselves, but from the pathogens they transmit through bites.
-
Malaria (transmitted by female Anopheles mosquitoes) claims approximately 670,000 lives;
-
Dengue fever causes around 53,000 deaths;
-
Japanese encephalitis accounts for 25,000 deaths;
-
Yellow fever kills about 4,400 people;
-
Chikungunya causes 3,700 deaths.
An additional few hundred deaths are caused by West Nile virus, while Zika virus accounts for negligible mortality. The vast majority of these cases occur in Africa.
Land and Water Hazards
Snakes rank third, killing between 81,000 and 138,000 people annually. The wide estimation range is due to the fact that most incidents occur in developing countries with limited access to modern healthcare.
In fourth place is a surprising entry: dogs. Our canine companions cause between 6,600 and 70,000 deaths per year. The vast majority of these deaths are not caused by physical attacks, but by rabies transmission in underdeveloped nations.
Freshwater snails rank fifth, transmitting schistosomiasis, which kills between 11,700 and 14,100 people annually. They are followed by assassin bugs (kissing bugs) in sixth place, which transmit Chagas disease and cause 6,500 to 10,000 deaths, mostly in Central and South America.
Flies occupy the seventh spot:
-
Sandflies (transmitting leishmaniasis) cause between 1,800 and 8,700 deaths;
-
Tsetse flies (transmitting sleeping sickness) cause 700 to 2,500 deaths.
Intestinal worms (roundworms and tapeworms) rank eighth, causing up to 12,000 deaths combined. Scorpions are ninth with approximately 3,000 deaths, and elephants rank tenth, killing around 1,000 people annually, with rising trends reported in India and Sri Lanka.
The Second Deadliest Creature
The second spot on this list belongs to humans. We kill approximately 600,000 of our own kind every year:
"About 435,000 people die from interpersonal violence, 160,000 in wars and terrorism, and approximately 9,000 in law enforcement actions."
This figure excludes traffic accidents and suicides, which are also human-caused. Among larger wild animals, hippopotamuses stand out as the most dangerous safari animals, killing over 50 people annually.
