11 reasons mosquitoes are the most dangerous species on Earth

Mosquitoes are not only annoying, they also spread many deadly diseases. Therefore, mosquitoes are one of the most dangerous species on Earth.

>>>Why are some people not bitten by mosquitoes?

Yes, the most dangerous animals on earth can be killed by us with a fist - but if they bite us, they may have caused us to have a deadly disease.

Diseases transmitted by mosquitoes and "mosquitoes" kill more than a million people each year and infect diseases for more than a billion people, causing depression, pain, brain damage, blindness and images. Other serious effects.

Currently, half of the world's population is considered to be at high risk of diseases transmitted by blood-sucking bugs such as ticks, lice and mosquitoes. Today is the World Health Day, World Health Organization (WHO) has warned of a very real risk with a strong slogan: "A small bite, a great danger".

Globally, the most dangerous animals carrying pathogens and infectious diseases are mosquitoes. Here are 11 reasons why mosquitoes are the most dangerous by the Business Insider page:

1. Mosquitoes make 40% of the world population at risk of dengue fever

Dengue fever makes the patient very sick, feeling like a broken bone. It's a mosquito-borne disease, which has the fastest spread rate in the world, with 40% of the world's population facing risks. Each year, 50 to 100 million people suffer from dengue. Although often non-fatal, dengue is still a leading cause of death for children in some Latin American and Asian countries.

It can also develop into severe bleeding, which is much more dangerous, causing bleeding, organ failure and continuous vomiting.

There is no medicine or vaccine to prevent dengue fever. Treatments are usually just trying to keep patients hydrated.

2. Mosquitoes spread yellow fever

Each year about 200,000 people get yellow fever - and 30,000 deaths. It is a form of dengue without treatment. After a period of severe illness, most patients recovered, but about 15% had toxic complications, began internal bleeding and disorders of internal organs. About half of patients have fatal complications.

Cases of yellow fever have increased since the 1980s due to reduced human immunity, deforestation, climate change, increased air travel, and higher rates of infection in cities. Aedes aegypti is called a mosquito by a mosquito.

However, there are vaccines that are effective for this disease - a single dose will provide lifelong immunity. Many countries do not allow tourists to enter the country if they are not vaccinated.

3. Mosquitoes cause chikungunya fever

Chikungunya fever is a disease caused by the chikungunya virus that is transmitted by an infected mosquito. The disease has existed in the world for centuries, but only appeared in America for the first time in late 2013.

The name of the disease comes from a word in the Tanzanian language, which means "distorted," meaning the disease causes severe joint pain, which lasts for weeks, and in some cases can prolong the row. month and year.

"I was in Africa and witnessed children screaming for a long day because of the pain caused by chikungunya," said Mosquito Control Association Joe Conlon.

Humans have very little natural immunity to chikungunya, so mosquitoes can spread the chikungunya virus very quickly across the population. In 2005, an outbreak of chikungunya on the island of La Reunión (France) infected 200,000 of the 750,000 residents here, although mosquitoes on the island are Asian Tiger Mosquitoes. spread virus chikungunya. However, experts recognize that this species has changed and is capable of spreading the disease.

4. Mosquitoes turn individual cases into epidemics

Any person infected with mosquitoes can take it to another country, and cause disease if they are bitten by another mosquito - this happens very often.

In 2007, an Italian man came home from India, accidentally being bitten by a mosquito carrying chikungunya. When he returned home, he visited a cousin - and within 3 months, more than 200 people were infected.

5. Mosquitoes make people also suffer from poultry diseases

Although West Nile virus is only found in birds, humans can get it - usually from a mosquito biting the bird. Most people have no symptoms, but 20% of people have a fever - accompanied by headache, body aches, joint pain, vomiting, diarrhea, or rash.

In 150 cases, there is about 1 more severe progression to West Nile encephalitis or West Nile meningitis, both of which are potentially fatal. Horses may also be infected by West Nile virus. but whether horses or people can spread into epidemics. And while there is a vaccine for this disease, there is no vaccine for humans.

6. Are mosquitoes not fair, some people are more likely to be bitten by mosquitoes than others?

Some people really are mosquito magnet magnets. Mosquitoes are attracted by the smell emitted by bacteria that live on human skin, and some people give off smells that make them especially attractive to beetles. Contrary to what many people say, eating garlic or using natural mosquito repellent is not effective.

7. Mosquitoes spread the Rift Valley fever, which can cause blindness

Rift Valley fever mainly affects animals, but mosquitoes can infect people, and it has terrible symptoms.

Some people do not appear symptoms. But those with symptoms, at first, will feel like they have the flu, then some become stiff and uncomfortable with light. A small number (less than 2%) can suffer eye injuries that make them blind, while others (less than 2%) can develop into a form of brain disease, potentially fatal. death or dengue fever.

Because Rift Valley fever primarily affects animals, it can make agriculture and the economy reel.

8. Mosquitoes can permanently make patients sick

Lymphatic filariasis, a virtually forgotten tropical disease, is a leading cause of permanent injuries for people around the world.

Currently, more than 120 million people are infected with this disease, and about a third of them are deformed, disabled due to the disease.

Mosquitoes spread parasites between humans, then penetrate into the lymphatic system and proliferate over a period of 6-8 years. They can damage the immune system and kidneys, which can later cause painful swelling in the arms, legs, and genitals.

9. Mosquitoes transmit death diseases to children

Although not spread among people, Japanese encephalitis can spread from animals to humans by mosquitoes. This disease kills about 10,000 people every year, mostly children under 5 years old. Although there is no treatment for Japanese encephalitis, you have an effective vaccine to prevent it.

10. Mosquitoes that spread malaria cause hundreds of thousands of deaths each year

Between 2000 and 2012, malaria mortality has dropped significantly - 42% globally. Even so, it is estimated that in 2012 alone, about 627,000 people died from malaria and about 207 million people contracted the disease.

Anopheles mosquitoes transmit Plasmodium parasites in their bite, then cause high fever, chills, and severe flu-like symptoms, which can be fatal if left untreated. The disease can be prevented by having bed nets, insect repellent, wearing long-sleeved shirts, and can be treated, but it still causes many deaths.

11. Mosquitoes are difficult to destroy completely

Remember, the mosquito is an insect species and has been present on Earth for 170 million years, it is difficult to destroy them at its root. Mosquitoes do not need many conditions to live. Any small water container - or anything that can catch rainwater - is enough for mosquitoes to breed. Mosquitoes are also becoming resistant to conventional killers.

Mosquitoes also move very quickly. The Asian Tiger Mosquito, which can cause yellow fever, dengue fever, and chikungunya, has spread to 36 states in the US since its first appearance in 1985.
