rat mite bites
Introduction
Introduction to rat bites The rat bites (ornithonyssussting) are caused by biting humans on the parasitic mouse body and may be related to the source of the reaction. Occurs in the neck and shoulders, waist and abdomen and limbs, usually diffusely distributed rice grains to soybeans big pimples, wind group, do not blend with each other, itching is severe, local symptomatic treatment. basic knowledge The proportion of sickness: 0.01%-0.05% Susceptible people: no special people Mode of infection: non-infectious Complications: Plague, generalized purulent infection, epidemic hemorrhagic fever
Cause
Cause of rat bite
(1) Causes of the disease
The ornithonyssus sting is caused by a bite of a scorpionfish on the parasitic mouse body and may be related to the source of the reaction.
(two) pathogenesis
It is not very clear at present and may be related to the source of the reaction.
Prevention
Rat bite prevention
Do a good job in environmental hygiene and eliminate mice. The control of human bite disease is important in prevention. Prevention of rodent disease should adopt comprehensive prevention and treatment measures: 1 early detection, correct diagnosis and treatment of patients with Demodex infection; 2 improve environmental sanitation conditions, develop good hygiene habits, wash basins, towels, etc. in the family, often Boil, reduce the chance of transmission. Bathing, drying pillows, bedding; 3 strict disinfection of beauty, massage and other public places to prevent mutual infection. Other preventive measures include the breeding of natural enemies such as cats, and the removal of garbage and debris can reduce the breeding of rodents and reduce the incidence of this disease.
Complication
Rat bite complications Complications, plague, generalized purulent infection, epidemic hemorrhagic fever
In addition to causing damage to the skin and mucous membranes, the disease can also spread other diseases, such as epidemic hemorrhagic fever and even plague. The plague is a Class A infectious disease. If the patient is bitten, severe vomiting and diarrhea appear, and the stool appears. The characteristic faecal stool of the "rice-like" plague needs to be alert to the disease, and the disease is immediately treated. Due to the ulceration of the skin mucosa, patients often have a suppurative infection of the skin mucosa.

Diagnosis
Mouse bite diagnosis
Diagnosis can be based on clinical manifestations.
According to the clinical manifestations of this disease, the disease should be identified with the following diseases:
1. The papular urticaria rash often occurs suddenly, and has little to do with the season. It does not necessarily have a history of contact with grains and weeds, and it is not easy to find the worms.
