For example, mosquitoes can transmit malaria, yellow fever and West Nile virus, which can cause a variety of tropical diseases; Vampire bats, on the other hand, can transmit dysentery, typhoid, night blindness and pernicious anemia viruses, which may cause blood clotting disorders and hemorrhagic diseases; Ticks can also transmit diseases such as forest encephalitis.

Therefore, in the wild environment, humans should avoid close contact with these blood-sucking animals to reduce the risk of contracting diseases.

Mosquitoes are very harmful to humans, female mosquitoes will draw nutrients from the blood of humans and other animals, they carry a variety of pathogenic bacteria and viruses, may cause serious consequences, and even cause human death, the number of direct or indirect human deaths caused by mosquitoes ranks first every year, causing 725,000 deaths every year.

Therefore, in order to reduce the harm of mosquitoes to humans, effective measures should be actively taken. First of all, the environment should be changed to avoid the accumulation of sewage to prevent the breeding of mosquitoes. Secondly, garbage should be swept frequently and disinfected regularly.

In addition, mosquito nets can be installed at home and mosquito repellents can be used in places that are vulnerable to mosquitoes, all of which can effectively reduce the harm of mosquitoes to humans.

Vampire bats

Vampire bats are pterodactylus mammals that live in the Americas, they have different habits from common bats, and like to suck animal and human blood after nightfall to obtain nutrients from them. Scientists have found only three species of vampire bats, which also differ in appearance from one another.

Most of the time, vampire bats only suck the blood of large mammals or birds, and sometimes suck the blood of sleeping humans, because there are a large number of viruses and bacteria on the body of bats, so vampire bats will also be harmful to people.

They will use ultrasound to find prey, observe whether it is asleep, they will first bite the hairless part of the prey, and then quickly jump away to see if the prey wakes up.

If the prey is still in a deep sleep, they will continue to bite open the skin of the prey and then lick the blood with their tongue. The saliva of vampire bats contains anticoagulant components, which can make the wounds of their prey bleed.

Due to their special habits, leeches are also often used in biological research and medical experiments, and leeches have been widely used as a medicinal herb.

Generally, leeches are about 2 to 5 cm long, and there are sharp mouthparts at the top of the head, which they can use to absorb their prey and then suck blood, that is, to draw water and nutrients from the blood of their prey for their own use.

Leeches may also bite humans, but most leeches do not pose a threat to humans, because they only feed on blood, do not cause virus and bacterial transmission, and do not cause direct harm to humans.
