What diseases do mosquitoes carry?

Mosquitoes are pesky insects that are found on all continents except Antarctica, and annually cause the death of 725 thousand people.
It would seem that in our latitudes deadly insects are practically not found, and mass infection with malaria was prevented in the sixties of the last century, so the greatest harm they can bring is a sleepless night and itchy bite marks.
Unfortunately, this is not the case.

Let us consider in more detail the diseases that these insects carry.

1 Meningitis is an inflammation of the brain and spinal cord.
Its symptoms are severe headache, weakness, fever, acute sensitivity to light or sound, fever and clouding of consciousness.
In the absence of proper treatment, meningitis can give very serious complications: hearing and vision impairment, hydrocephalus, paralysis and decreased mental abilities.
In 10% of cases, a fatal outcome is observed. Meningitis can be carried by real mosquitoes that pick up the pathogen in birds.

2 Japanese encephalitis, despite the name, is found not only in Japan, but also in almost the entire pacific region.
In Russia, you can get infected on the territory of primorsky Krai.
The disease manifests itself sharply, with the rapid onset of symptoms.
In the first days, there is general weakness, drowsiness and fatigue.
In the following days, there is fever, fever, headache, bifurcation of the image in the eyes, general deterioration of vision and conjunctivitis.
In the future, the patient’s transition to a coma is possible.
Mortality is observed in 40-70% of cases.
Japanese encephalitis is also carried by real mosquitoes.

3 malaria.
The same disease that carries the famous malaria mosquitoes.
The risk of getting bitten by a malaria mosquito and getting infected is quite low, but it is there.
Malaria mosquitoes live in the European part of Russia, Western Siberia and the south of the Far East.
When infected with malaria, the patient has a fever, aches in the joints, convulsions, high fever.
It is also possible a violation of cerebral circulation and an extremely severe headache.
Malaria can be fatal if the patient is not provided with timely medical care.
Children and pregnant women are most at risk.

4 Tularemia occurs in almost all latitudes of our country.
Annually recorded 150-250 cases of tularemia. The main vectors of infection are rodents and blood-sucking insects.
Tularemia is characterized by a sharp increase in temperature to 38.5-40 ° C.
There is a severe headache, weakness, dizziness, pain in the muscles and joints.
There is a change in consciousness against the background of high temperature.
External signs – a gray coating on the tongue and point hemorrhages throughout the oral cavity.
The lymph nodes are greatly enlarged, swelling and redness of the face occur.
There is also a bubonic form of this disease, characterized by the appearance of buboes with pus.
A patient with tularemia must be hospitalized, otherwise complications and death are possible.
Tularemia is carried by burning and real mosquitoes.

5 Allergy to mosquitoes is not an infectious disease, but it is no less dangerous.
In addition, allergies are much more common than the same malaria.
The bite of an allergic mosquito can cause swelling, severe itching, rash.
A reaction from the gastrointestinal tract is possible – nausea, vomiting, abdominal pain and diarrhea.
The most dangerous factor is the possibility of suffocation due to laryngeal edema or anaphylactic shock.
If, after a mosquito bite, a person has severe swelling of the face, neck and head and it has become difficult to breathe, you should immediately take him to the doctor.

How to protect yourself from mosquito bites?

The greatest risk of catching the diseases described above occurs when going out into nature.
Forests, meadows, swamps, rivers and lakes are teeming with mosquitoes.
To protect yourself from bites and their consequences, you need to follow a few simple rules:

  • Use tight and light clothing, maximally covering all parts of the body.
    Wear a hood, hat or anti-enacephalitis suits – they have a hood with a small mesh on the face.
  • Do not use strongly smelling perfumes and deodorants – mosquitoes are attracted to sharp and strong smells.
    It is also not superfluous to take a shower or swim in a pond – in addition to the aroma of perfume, mosquitoes are guided by the smell of sweat.
  • Use repellents. For example, take with you to nature napkins “Nechesun”.
    It is a convenient, compact and effective tool.
  • If you are allergic, carry antihistamines with you.
