Dangerous to humans diseases are often transmitted through the blood. They can be infected in various ways, including through mosquitoes, which transmit about 50 diseases. In the selection of cheltv.ru – 5 of the most dangerous diseases that can be obtained from small annoying vampires.
Malaria
Perhaps the most famous disease transmitted by mosquitoes is malaria. But the disease itself is provoked not by insects, but by unicellular parasite creatures – plasmodia.
The main symptoms of the disease are fever, chills, anemia and an increase in the size of the liver and spleen. This disease affects up to 300 million people every year, and its mortality rate is approximately equal to 2-3%. Existing vaccine only helps in 50% of cases.

Malaria mosquitoes are called anoflesa. They are common everywhere except the Far North and deserts. Most malaria is affected in Africa.
Severe plasmodium climate in Russia allows us to contain the disease in our country. By the way, often the type of malaria mosquito, which lives in the Urals, is confused with long-lipped mosquitoes that feed on plant juices.
Dengue fever
This disease is most often found in travelers who have visited the Caribbean, as well as Central America and Central Asia. The main symptoms are a refusal to eat, chills, nausea, and insomnia.
Although the classic dengue fever is not very dangerous, it can develop into its hemorrhagic version, the mortality rate of which is estimated at 50%. Severe fever causes vomiting of blood, body temperature up to 40 degrees, weakness, low blood pressure.
Fortunately, this disease is not transmitted from person to person. Its main carrier is a species of mosquitoes called Kusaka Yellow feverish. From these insects can also become infected with yellow fever, which affects mainly the inhabitants of Africa. Both diseases affect about 50 million people each year.

West Nile Fever
Initially, this disease spread only in the tropics, but due to the development of tourism, it began to affect residents and other climatic zones. About 80% of cases of infection are asymptomatic, but mainly due to the disease, the temperature rises, sweating and chills appear.
A major outbreak of this disease in Russia was in 1999 in the Krasnodar Territory, Volgograd and Astrakhan Regions. The virus that causes the disease is most viable in the southern regions of our country and countries of the former USSR.
Eastern equine encephalitis
Common mosquitoes of the Culex pipiens species carry this disease. The main symptoms are cramps, fever, muscle pain and fear of light. In Russia, cases of this disease are recorded in Siberia.
The severity of the disease depends on the age of the patient. It is most dangerous for children under 15 years old and for people over 50 years old. In other ages, it is usually asymptomatic.
This encephalitis can affect the nervous system, as well as cause cerebral edema, therefore, in the case of a severe form of the disease, mortality reaches 60%.

Tularemia
Tularemia is a bacterial infection that ordinary mosquitoes and other blood-sucking can carry. It is characterized by severe poisoning (especially when infected through water and products where bacteria can get), fever, and also affects the skin.
In Russia, this disease occurs in almost all regions, and during World War II, large outbreaks caused mice. It is noteworthy that the disease has a bubonic form resembling a plague. Annually, up to 900 people get tularemia in Russia. The best way to fight bacteria is by treating with heat and boiling water.
