Bill Gates recently used an infographic to publicize a fight against diseases carried by mosquitoes.
Sharks are responsible for only ten human deaths a year. Around 100 people are killed every 12 months by lion, while crocodiles are responsible for about 1000 deaths in a year. Among the most dangerous animals listed in the graphic are dogs, at number four, due to 25,000 human deaths a year, mostly from rabies caught during dog attacks. The third-deadliest species for humans are snakes, which are responsible for 50,000 deaths every year.
Nearly ten times as many people meet their deaths at the hands of other people, totalling 475,000 annual fatalities. Mosquitoes are the world's number one killer.
The worst is malaria, which kills more than 600,000 people every year; In addition to malaria, several species of the animal can carry several other potentially deadly diseases, including encephalitis, dengue fever and yellow fever.
Mosquitoes are native to every area of the world, except Antarctica. There are more than 2,500 species of the flying insect known to mankind.
