A positive herpes simplex virus type 2 IgG antibody of 13.8 indicates a previous herpes simplex virus type 2 infection. Herpes simplex virus consists of IgG antibodies and IgM antibodies, of which elevated IgM antibodies have a strong reference to a recent herpes simplex virus type 2 infection, which needs to be searched for and treated aggressively. Herpes simplex virus type 2 IgG antibodies are produced a long time after infection, and in addition last for a very long time. Therefore, positive IgG antibodies indicate previous infection with herpes simplex virus type 2, which usually has no clinical symptoms at present and does not require special treatment. In order to reduce the recurrence of herpes simplex, you can pay attention to a reasonable diet, appropriate exercise, and improve immunity. If you find herpes simplex virus type 2 IgG antibody 13.8, it is recommended to consult a doctor immediately.
