How do crabs cause symptoms?

Some people are infected with asymptomatic crabs, crab disease symptoms.

Most patients are accompanied by varying degrees of itching. After the pores are partially bitten, they often show red or small erythema. Where there are blood scabs and micropores on it, allergic reactions may occur after 35 days, and papules may form. Very sensitive people may have papules or even big sores, and occasionally blue or light blue gray-green spots may appear, which are not itchy and do not fade when pressed, especially on the inner thighs, abdomen and waist. This is because of the bite of this pubic vampire, its saliva enters the patient's blood, and the hemoglobin changes color after leaving, and the micro-bleeding at the bite of lice becomes so blue. This fertile soil may exist in a few months. Because skin cancer is itchy, patients may have scratches, papules, scabs, nodules, even erosion, exudation, eczema or scratches, infectious HSV, folliculitis, furuncle and so on. Severe cases are accompanied by fever, general malaise, swollen lymph nodes nearby, headache, leukocytosis and other symptoms.

Crabs can infect eyelashes, eyebrows and eyelids and are called crabs. General treatment is given from the genital area to limit contact. If we look closely at the genitals, we can find crabs and lice eggs.
