The deadliest animal on the planet.

Mosquitoes are the world's deadliest animal, killing between 500,000 to over a million people per year, mainly due to their ability to spread diseases like malaria, dengue, and Zika. Mosquitoes are effective at spreading disease because they feed on blood, are small and winged, and share an ecosystem and resources with humans. While malaria is treatable, it can be very serious for high-risk people, such as small children and pregnant individuals. Snakes and rabies are also deadly to humans, but humans themselves are one of the deadliest creatures on Earth due to homicide and armed conflict. Preventative measures, such as window screens and mosquito nets, can help reduce the risk of mosquito-borne illnesses.
