Malaria is one of many diseases transmitted by mosquitoes, which kills more than 600,000 people every year. Every day, 200 million people get malaria due to mosquito transmission. This number far exceeds that of unfortunate victims bitten by crocodiles or wolves. According to the number of people who die of diseases every year, an infographic published by Bill Gates on his blog shows 15 kinds of the deadliest animals in the world: mosquitoes kill more people than all the other animals listed in the infographic combined.
Gates said: "Malaria threatens the life safety of half the world's population, and it causes billions of dollars in economic losses every year due to the loss of productivity." The Bill & Melinda Gates Foundation has long been working on ways to eradicate malaria and other mosquito-borne diseases such as dengue fever, yellow fever and encephalitis.
There are more than 2,500 species of mosquitoes in the world, which are distributed in more than 100 countries and every region except Antarctica. Gates said: "At the peak of the breeding season, the number of mosquitoes exceeds that of any other animal on earth except termites and ants. They have a great influence on the population distribution pattern. In many areas where malaria is rampant, the disease forces people to migrate inland, away from coastal areas that are more suitable for mosquitoes. "
Gates' infographic shows that only 10 people die from sharks, 100 people die from lions and 1000 people die from crocodiles every year, but they are all the most terrible animals. Murder and war kill 475 thousand people of the same kind every year, but schistosomiasis caused by freshwater snails, trypanosomiasis carried by insects, sleeping sickness transmitted by tsetse flies and rabies transmitted by dogs are many causes of death.
