Viral herpes is a relatively common disease in our lives and is somewhat contagious. Viral herpes is a viral skin disease caused by the viral herpes virus. The herpes simplex virus is widespread in the population and the human is the only host. The virus is present in the body of the patient or carrier, with the most virus in the rash herpes fluid, followed by the saliva, urine and stool of the patient or carrier, but with a slightly smaller amount of virus. There are many ways of transmission, mainly through direct contact with skin and mucous membranes. In a few cases, it is also transmitted sexually. For prevention of viral herpes, recurrent herpes simplex (this type is common) often occurs during and after febrile illnesses such as influenza and pneumonia, or when triggering factors such as menstruation, trauma, or mental stimulation occur. Therefore, in daily life, it is important to pay attention to personal hygiene, regular life, diet and regular living. Don’t do labor unintentionally. Enhance the immune function of the body. It is especially important to wash your hands regularly and change or wash your clothes in time when you come in contact with patients with shingles. Less contact with the patient, for the patient’s herpes in the liquid is most contagious, after contact must be disinfected.
