It can kill 700,000 people in a year! How terrible is it? Being bitten by it is not just a pus!
When it comes to the most dangerous creatures in the world, many people think of tigers and lions. But in fact, the humble mosquito is the most terrifying creature in the world.
According to WHO, about 700 million people fall ill every year from mosquito bites, resulting in 700,000 deaths. Many parts of the world "talk about mosquito discoloration", but where are mosquitoes terrible?
First of all, the mosquito bite process is even more terrifying than you think. The mosquito's blood-sucking mouth looks like a syringe, but it's actually six. When they suck blood, the six syringes have different divisions of labor, and the ends of the syringes on both sides have something like serrations, and the two serrated tubes are very sharp and can be easily inserted into human skin.
On the inside of these two jagged syringes are two slender syringes, whose role is to prop up the human skin and ensure that the main needle that sucks blood can be easily inserted. After these preparations, the main needle began to insert into the skin to find blood vessels, punctured the blood vessels and began to suck blood.
The remaining needle releases the mosquito's saliva, which contains a substance that allows the blood vessels to open and prevent blood from clotting, which allows the blood to flow more quickly to the main needle tube, allowing the mosquito to suck blood quickly.
In addition, when mosquitoes bite humans, they will also spray some acidic substances into the human body, and humans who are intolerant to this will be allergic to this, and the place where they are bitten by mosquitoes will usually be swollen and pimples, making people itchy and irritable.
Judging from the bacterial viruses carried by mosquitoes, they are complete "killers". One study showed that mosquitoes can transmit more than 80 diseases, including malaria and dengue fever, which kill people.
Malaria is mainly transmitted by a mosquito called Theops malaria mosquito, which is mostly distributed in tropical climates such as Africa and central South America, especially Africa, where a child dies of malaria about every 30 seconds. This is because the body of the mosquito mosquito contains the malaria parasite, which is the pathogen of malaria. They can destroy the body's normal red blood cells, resulting in liver, spleen and other organ lesions, and even deep into the bone marrow.
In addition to humans, mosquitoes can also transmit the malaria virus to animals, causing the death of animals.
Dengue fever is transmitted by the Aedes aegypti mosquito and the Aedes albopictus mosquito, and areas with hot weather and frequent rain are high incidence areas of dengue fever. About 100 million people are infected with the dengue virus each year, and the mortality rate is extremely high. Today, dengue fever has become the most prominent security problem in tropical and subtropical countries. So mosquitoes are the biggest pests on earth.
But such a terrible mosquito, can it really not go extinct? The answer is no. Mosquitoes are part of Earth's biological chain, and their natural enemies are bats. Bats living in dark caves feed on mosquitoes, and they can eat more than a dozen mosquitoes a minute, and they can eliminate more than fifteen thousand mosquitoes in a day.
Even so, mosquitoes cannot be completely eliminated. Because the natural enemies of mosquitoes, bats, like mosquitoes, are the species that carry the most viruses, once the mosquitoes become extinct, the bats are bound to come out to find food to eat, and there will be more disasters to humans.
Mosquitoes may seem small, but they are the biggest threat to human life. Since mosquitoes cannot be completely eliminated, they can only do their own mosquito repellent work to avoid being bitten by mosquitoes.
