Human civilization has developed to this day, and it is still impossible to avoid the life threats brought to humans by some animals. So do you know which animals in the world have the greatest threat to humans?
The first reaction of many people is that large animals such as mighty lions, tigers, and bears do not know that the killer animals that are truly hidden around us are all inconspicuous "little" animals that can kill people silently.
What are the "little" animal killers? Let's reveal the secrets one by one.
No. 7 - Scorpion
People in the world often use "poisonous scorpion heart" to describe a person's viciousness. The reason is that the toxicity of scorpion is really terrifying.
But in fact, not all scorpions can kill people. After stinging a person, a scorpion often has a severe burning sensation and is accompanied by swelling. If treated in time, it will generally be fine.
But there are several types of scorpions in the world, but it is different, for example, Palestinian scorpion . If it is known as the second scorpion in the scorpion world, then no scorpion dares to rank first in its poisonousness. How toxic is
?
The adult Palestinian scorpion is extremely aggressive. Once the venom is stabbed on its tail, it will cause respiratory failure, paralysis, or stop heartbeat in extreme pain.
and the Mediterranean yellow scorpion. Although it looks very inconspicuous, its toxicity is also particularly fatal. Anyone who sees it will take a detour.
In addition, there are also yellow fat-tailed scorpion , Asian rainforest scorpion , Mexican statue wood scorpion , etc., all of which are famous venomous scorpion.
According to statistics, there are basically more than 3,000 people who are stung by these poisonous scorpions every year.
No. 6 - cone bug
cone bug has two nicknames, one is "Psyllid King". Due to its reproduction, a large number of insect eggs will generally hide in corners like a house, or a place where animals live, so this title is given.
This insect is mainly distributed in Latin America, especially in some poor residential areas. Adult cone bugs are generally about 2.5 cm in size and are large. They like to suck the body fluids of similar flies, or bite animals and humans, and suck blood.
and its other nickname is better, called " kissing insect ". Because cone bugs like to appear at night, especially after people sleep well, they will find weaker places in the human skin for bites, especially on the face, such as lips, eyelids, etc.
Although most cone bugs are greedy and absorb a lot of blood, their movements are gentler, and there is no pain in the wounds they bit by, so there is such a gentle nickname.
However, there are some species of cone bugs, which feel very painful after biting people. There are often large lumps or swelling in the bitten areas, and some local skin can also cause urticaria.
The most terrifying thing is that after sucking blood, cone bugs will generally discharge a small amount of feces from their bodies, leaving them in the bitten wound, which contains a large amount of parasites, which invade human or animal bodies through the wound, or mouth and nose. Once the parasite
enters the human body, it will go straight to the heart and survive in the heart. People who are infected will often experience arrhythmia , or heart failure .
The disease caused by cone bug is called "Trypanosomavirus". The early symptoms of this disease are very similar to AIDS and are extremely transmissible.
Since it is mainly transmitted by blood, once a pregnant woman suffers from this disease, it is very likely to be infected with the fetus in the abdomen.
, and this disease is also extremely hidden.
At the beginning of the infection, it will first have an acute attack. Body temperature rises, facial edema, and accompanied by anemia.It takes up to 3 months and is constantly relying on a large number of drugs for controlled treatment.
Many poor people often choose to fend for themselves because the treatment drugs are too expensive.
. Although some relatively wealthy patients have survived the initial dangerous period with drugs, this disease cannot be cured at all.
It will continue to hide in the human body for several years or even decades, during which the infected person will experience heart hypertrophy or intestinal hypertrophy.
Once the disease occurs again, will be heart failure , and the internal organs that become hypertrophic suddenly burst, and the patient will die without time for treatment.
The fatal disease caused by cone bugs is more than 12,000 per year.
No. 5 - Tsetse fly
Tsetse fly, there are more than 30 species, mainly in Africa. Their body size is generally smaller than ordinary flies, and they mainly rely on sucking domestic animals, humans, or wild animals for their lives.
Although the tsetse fly is only one centimeter in size, its mouthparts are extremely sharp. Anyone or animal that has been bitten by it will have a high fever, be drowsy, or even become unconscious.
In severe cases, it can also cause neurological disorders and cause death.
The danger of Tsetse fly is that it carries countless tiny conical parasites in its body. While it sucks blood, these parasites will enter the blood-sucked living organisms. Once the treatment is not done in time, it is very likely to die.
According to relevant institutions, more than 3 million livestock die from tsetse flies every year in Africa, thus causing no less than 4 billion US dollars in direct economic losses to local residents.
Although all African countries are actively taking measures to completely eliminate tsetse flies, because its larvae survival rate is extremely high and its growth cycle is also fast, the effect of killing tsetse flies has always been unsatisfactory.
Every year, the number of people who die from tsetse flies is as high as 50,000.
fourth place - dog
September 28th of each year is World Rabies Day , which shows the deep fear that rabies brings to humans.
Smart and kind dogs have always been the most loyal companions of humans and are also the pets raised by humans the most in the world.
therefore has also made it the main factor in infecting humans rabies virus .
Since rabies virus is mainly transmitted by saliva, once a human is bitten by a dog suffering from rabies, there is a high probability of being infected. Once you get infected with rabies, the mortality rate will be 100%
However, rabies virus has a long incubation period, so many people will only feel hot or unbearable pain in the wound that is bitten when they are first infected.
But as the virus spreads in the body, it will destroy the human nervous system, and even infect the brain stem, causing people to become mentally ill.
Once rabies occur, there will be no cure.
So humans have actively developed vaccines against rabies virus. Many pet dogs will be taken to the vaccination by their owners as soon as they are born, thus reducing the possibility of many pet dogs being infected with rabies virus.
However, there are still a large number of stray dogs in the world. Because of their poor living environment, they are more likely to carry rabies virus. If someone is bitten by them, they need to go to the hospital to get rabies vaccine in time.
So here to advise those who often have dogs around you to take safety protection to avoid tragedy.
After all, as many as 55,000 people die every year because they are bitten by dogs with rabies.
third place - freshwater snail
Looking at the weak snail, this slow crawling mollusk , many people even treat it as a meal on the plate, but eating a wild freshwater snail may cause death.
The key reason is that snails living in various rivers and lakes have a large number of schistosomiasis parasitizes in their bodies.
Their eggs will enter the water through the snail's excrement, hatch into miraculous cercia, and then temporarily parasitize into snail for secondary development, and tens of thousands of cercia will reproduce soon.
The grown cercariae will automatically break away from the snail and return to the water to move. Once you meet someone who goes into the water, they will immediately drill into the human skin and into the blood, thus causing people to suffer from schistosomiasis.
In a short period of time, people with this disease will become itchy, red and rash, which looks like they are allergic. After a few days, these symptoms will subside, and then there will be headaches, fevers, and diarrhea.
Because parasites have the ability to reproduce very quickly in the human body, they will soon invade various important organs in the human body and cause damage. At this time, the infected people will gradually develop language and movement obstacles.
As the human body's immunity decreases, all organs will degenerate and eventually die.
Some people who live by the river and rely extremely on the river water are easily infected with schistosomiasis.
Due to the unique way of survival and reproduction of Schistosoma schistosomiasis, people who had previously had relatively difficult living conditions would directly treat the water from natural rivers as daily water, so a large number of people died from schistosomiasis.
In related fields in my country, the existence of schistosomiasis has a history of more than 2,100 years.
With the improvement of human living standards and medical conditions, the occurrence of schistosomiasis is also greatly reduced.
However, schistosomiasis caused by freshwater snails every year can still cause nearly 200,000 people to lose their lives.
second place - snake
snake. I believe many people are familiar with it, especially thinking about its cold and smooth skin and the bright red snake letters spit out from their mouths, which is enough to make people shudder.
There are many types of snakes. Although there are many snake-catching experts who can distinguish between poisonous and non-toxic snakes and bring some undestructive snakes to the dining table, no matter how experienced the experienced people are, they will inevitably fail in front of cold-blooded animals such as snakes.
The most venomous snake in the world - the sea snake, can kill people with only 0.01 mg of toxin.
Because it lives in water for a long time, there are relatively limited people who can get in touch with it. In addition, its temperament is relatively mild, so it often does not actively attack humans, but if someone provokes it, the final outcome of the person will be very miserable.
The sea snake bites people, and the human body has almost no pain. Maybe it cannot detect where it bites, but its venom will directly destroy the human body's random muscles .
Because its toxins have a long incubation period in the human body, many people don’t know or care about it at the beginning of being bitten, but gradually they will feel tired and weak in their limbs, and they will die.
King Cobra , I believe many people have heard of its name. It has a nickname called "Snake Evil Star". Once
is bitten by it, it will be injected into a large amount of venom, which can directly cause to shock or respiratory failure in the human body. If you are not treated in time, you will die.
There are also African tree snakes. Many people may not have heard of it. This snake has a very gorgeous appearance and is very good at disguising. It is very toxic. With its super vision, it will be difficult to avoid it as long as it is targeted.
People who are bitten by it will most likely suffer from severe organ bleeding. If you want to treat it, you can only rely on specific serums, otherwise you will have to wait for death. Moreover, the process of death is extremely painful, and the death is particularly miserable.
is known as the fastest snake in the world - black mamba snake . Its black appearance makes people feel scared, and there is no doubt about its toxicity. If you bite it, it will cause heart failure in a short period of time.
In addition, there are also Eastern Brown Snake , tiger spotted rattlesnake, Golden Ring Snake , Tiger Snake , Viper , Taipan Snake , etc. They are all very famous venomous snakes in the world.
The number of people killed by these unfeeling snakes is as high as more than 200,000 every year.
No. 1 - Mosquito
I didn’t expect that the little mosquito would be the number one killer that threatens human life.
Although mosquitoes are small in size, there are more than 80 diseases they can carry and spread.
Many people only have the impression of it in the unbearable red and swollen hard bag after being bitten by it, but I don’t know how many lives it has taken away because of its bite.
According to statistics, among all humans in the world, at least more than 700 million people suffer from various diseases due to mosquito bites every year, and one out of every 17 people will die due to ineffective treatment.
like malaria , dengue , and these terrifying infectious diseases will be transmitted by mosquitoes.
There are more than 3,600 kinds of mosquitoes in the world, and each type of mosquito can become a vector of viruses and spread different viruses.
mosquitoes have extremely strong perception ability. They can quickly lock the target human body through odor, body temperature, color, carbon dioxide concentration exhaled by the human body, as well as the lactic acid secreted by the human skin, and so on, so as to quietly climb up the human skin to complete blood sucking.
Due to the super reproductive ability of mosquitoes, no matter what means humans use, they cannot be completely eliminated.
The four recognized regions in the world: Amazon River in South America, in Africa, in Lake Chad, Lake Tangalka, and Beiwan, Habahe County, Xinjiang. It can be called a paradise for mosquitoes.
In these places, it is easy for mosquitoes to kill people.
However, studies have found that not all mosquitoes in the world are harmful to humans. Apart from mosquitoes that spread diseases, there are mosquitoes that can spread pollen.
Mosquitoes actually play an indispensable role in the entire natural ecosystem.
In short, no matter what the reason is, it is impossible for mosquitoes to disappear completely from this world. All we can do is take active measures to prevent being bitten by it.
After all, this number one killer that threatens human life can kill more than 720,000 people every year.
No matter which animal is a product of nature, it cannot be avoided to coexist with them, then we must maintain a sense of awe. After all, everyone has only one life, so don’t be careless!
