The tick, which is referred to as arachnid small insects, feeds, as a rule, on the blood of animals. However, there are species that pose a danger to humans. The blood-sucking insect is a carrier of various diseases. When bitten, it can infect a person with tick-borne encephalitis or borreliosis, hemorrhagic fever, or Lyme disease.
The insect mainly lives in the grass, sometimes in low bushes. On the paws of the tick are microscopic claws that allow it to firmly fix on its victim. After getting on the human body, the insect tries to climb as high as possible (into the armpits, on the back, neck or shoulders). That is why the bloodsucking does not immediately penetrate the skin. A tick bite in a person (photo you see below) does not cause pain. This is because its saliva contains a special substance. It has a strong analgesic property. That is why it is difficult to detect an insect that sticks to a blood vessel and disappears only after saturation.
In the event that a suspicious tubercle appears on the human body, it should be carefully considered. First aid for tick bites should be provided by a doctor. You should not independently remove the insect that has sunk into it from the skin.
In the event that
a tick bite has occurred
, the symptoms of a person who has entered the bloodstream with an encephalitis infection usually appear after ten days. Diagnosis of the disease is possible only during laboratory tests of a patient’s blood test. Initial measures that are taken after an insect bite should be aimed at preventing the further development of a dangerous disease.
After a tick bite has occurred, the person’s symptoms of encephalitis appear depending on the state of the immune forces, as well as the virulence of the virus. Sometimes the disease is quite easy. With a severe form of the disease, signs of central nervous system damage appear.
After a tick bite has occurred, the person's symptoms of encephalitis begin to appear in the second week of infection. The disease can take various forms: febrile and meningeal, as well as meningoencephalitis and poliomyelitis. Any type of infection at the initial stage is manifested by chills, aching in the whole body, an increase in temperature to thirty-eight to forty degrees. Symptoms of a febrile form of encephalitis are also manifested in severe weakness, nausea, loss of appetite, and headache. This virus does not disrupt the central nervous system. The manifestation of fever lasts up to ten days.
In the event that an infection of the meningeal form of encephalitis occurs, a headache, photophobia, vomiting, and various manifestations of irritation of the meninges appear on the background of a febrile state. The poliomyelitic and meningoencephalitic type of infection is supplemented by such symptoms of the disease as impaired consciousness, paralysis, convulsions and mental disorders.
After a tick bite has occurred, the person’s symptoms of another dangerous disease - borreliosis - are expressed by redness in the focus of infection, which appears seven days later and gradually increases in size. Signs of the occurrence of pathology are: fever and headache, constant fatigue and body aches. With the advanced form of borreliosis, the joints, heart and central nervous system are affected.
