Herpes, clinically common are mainly herpes zoster, herpes simplex and genital herpes. The recurrence rate of herpes zoster is not very high, and usually normal people only get it once in their lifetime. When the immunity is very poor, such as having a malignant tumor, AIDS, etc., it may lead to a recurrence of herpes zoster. Herpes simplex, as well as genital herpes, are both infected by the herpes simplex virus.1. Herpes simplex: It is an infection by the herpes simplex virus type 1, which is mainly found on the face and at the mucosal junction of the mouth and lips.2. Genital herpes: It is caused by the herpes simplex virus type 2 infection, which is a sexually transmitted disease. When the virus content is low, it will be latent in the ganglion, when the body’s immunity is low, the virus will increase replication, and gradually distributed along the nerve to the skin, thus leading to recurrence. Nowadays, medication, which has not completely killed the virus, only inhibits the replication of the virus, so it is difficult to kill the virus completely.
