What symptom does splenic insect bite have

First, ticks have no pain when biting and sucking blood. However, because of the lower plate of the chela and penetrating into the host at the same time, it can cause local congestion, edema, acute inflammatory reaction and secondary infection. In the process of biting and sucking blood, some ticks secrete neurotoxins in saliva, which can lead to the conduction disorder of host motor fibers, cause ascending muscle paralysis, and cause respiratory failure and death.

Second: after the tick bites, it will send out a kind of anesthesia, burying the head in the skin to suck blood. At the same time, it secretes a kind of substance that can be harmful to the human body, which needs to be taken out in time. If it is not taken out in time, the light patients will itch hard after a few years, and the severe patients will have high fever, deep coma and convulsion, causing forest encephalitis.

Third, ticks can infect human peripheral blood neutrophils after biting. Fever with white blood cells, thrombocytopenia and multiple organ dysfunction are the main clinical manifestations. The main symptoms are fever with general discomfort, headache and fatigue, muscle soreness, nausea, vomiting, anorexia, mental impotence, etc.
