One of the most annoying insects in the world,mosquitoes are undoubtedly. Currently, scientists know about 3,600 species, with about 100 of them living in Russia. Not only that, with their bites, they are able to turn the evening outdoor recreation into hell, they can also infect a person with dangerous diseases. Most often, these insects spread yellow fever and Zika virus, but scientists recently noticed that mosquitoes have also begun to actively spread a rather rare disease that can cause brain inflammation and agonizing death.
This disease is known as the eastern horseencephalitis and is considered very dangerous, because during infection a person dies in 30-50% of cases. The virus, which is the source of the disease, enters the human body after a mosquito bite and through the blood reaches the brain and causes its inflammation. Common symptoms of infection are drowsiness, headache and cramps - sometimes the brain is disturbed to the extent that a person dies. Even if the patient survives the disease, she does not disappear without a trace and leaves behind various problems. For example, a person can have epileptic seizures and at least often have a headache.
Mosquitoes that spread horse encephalitis,Usually live in the marshlands of warmer areas of the United States, such as the states of Florida and Texas. Fortunately, cases of infection with the disease are extremely rare, because people rarely appear in swampy areas. In addition, the mosquito becomes infected in marsh bugs, and not in humans - in the human body the virus multiplies too slowly and its concentration is not enough to penetrate the body of a healthy mosquito. In 2016, horse encephalitis was diagnosed only in six people.
The tiger mosquito is one of the most dangerous in the world.
It may seem that this disease is not sodangerous, but scientists believe that in the future it may become more common. The fact is that because of the climatic changes that are causing our planet extreme damage, infectious mosquitoes are looking for new habitats. For example, Asian tiger mosquitoes used to be found only in China, Japan and Australia, but in 2017 they were found even in Russia. Perhaps the day is not far when mosquitoes with horse encephalitis will fly to Russia and European countries.
How to protect yourself from mosquitoes?
The worst thing is that from this disease yetmedication - a person either dies or survives and lives with a headache and epileptic seizures. While there is no vaccine, scientists are trying to find other ways to stop the spread of mosquito-borne diseases. The most effective of them was demonstrated in China - scientists were able to destroy the populations of infected mosquitoes with the help of radiation and biological weapons. It sounds scary, but the method is completely safe for people and clearly pleased the locals, who were probably afraid of terrible diseases.

Currently, contagious mosquitoes are being destroyed.only in certain parts of the planet. Everyone else who is afraid of mosquito bites, it is recommended to use repellents - chemical means to repel insects. After applying them to the skin or clothing, you can see that insects really avoid you, because the substances irritate their nerve endings. By the way, do not confuse repellents with insecticides, because the latter are designed to kill insects, and not scaring.
