Herpes simplex, clinically, is divided into infection with herpes simplex type I and type II, where type I herpes simplex virus, mainly occurs in the mucous membrane of the mouth and lips, eyelids, nose, etc., while herpes simplex virus type II infection tends to occur in the vulva, perianal area, etc. The appropriate tests are performed, such as IgG positive, which often represents a previous infection, and IgM, which is often a presenting infection. Herpes simplex virus IgG positive means that the infection has occurred before, and even if there are recent skin lesions, the condition has emerged due to a relapse.
