Genital herpes is a herpetic rash that grows on the genital area when the body is infected with the herpes simplex virus and has a flare-up, and the symptoms are obvious. After the onset of genital herpes, patients commonly experience erythematous blisters on the skin around the anus and genital area. Previously, the skin may feel itchy or burning, and the blisters may grow in clusters of several or may be scattered in small numbers. After a period of time, the blisters may rupture, causing superficial ulceration or erosion of the skin, which may be painful. At the same time, unilateral lymph nodes around the abdomen and buttocks may become enlarged and painful when pressed. Many patients may also have systemic symptoms, such as headache and fever and weakness of the limbs. The clinical symptoms of the disease are obvious, and the diagnosis can be made by the doctor with the patient’s presentation and past medical history, or by cytological examination and viral culture. The patient himself should keep the affected area dry and clean, using saline to wash it properly and not scratching it to avoid bacterial infection. The main manifestation of genital herpes is the growth of blisters on the skin of the anus and genital area, which can rupture and cause erosion.
