The world’s deadliest animals

World s deadliest animals

During the Gates Notes Mosquito Week Bill Gates posted this Chart-of-the-Year.

(…snip…) What makes mosquitoes so dangerous? Despite their innocuous-sounding name—Spanish for “little fly”—they carry devastating diseases. The worst is malaria, which kills more than 600,000 people every year; another 200 million cases incapacitate people for days at a time. It threatens half of the world’s population and causes billions of dollars in lost productivity annually. Other mosquito-borne diseases include dengue fever, yellow fever, and encephalitis.

There are more than 2,500 species of mosquito, and mosquitoes are found in every region of the world except Antarctica. During the peak breeding seasons, they outnumber every other animal on Earth, except termites and ants. They were responsible for tens of thousands of deaths during the construction of the Panama Canal. And they affect population patterns on a grand scale: In many malarial zones, the disease drives people inland and away from the coast, where the climate is more welcoming to mosquitoes.
