Herpes simplex virus type 2 refers to the external genital herpes virus. A positive IgG antibody indicates a previous infection and does not indicate a current infection, so there is nothing to worry about if it is judged that there is no current infection. For people with normal immune function there is no need to worry, even for those who are pregnant. If it is judged that there is a current infection, it is likely that appropriate treatment will be needed at this time, or to prevent physical harm from being caused. It can be judged by the symptoms, if there is herpes of the external genitalia, it means that there is a recurrent infection, which can be treated with drugs for normal people, such as oral acyclovir, valacyclovir, famciclovir and other antiviral drugs. In pregnant women, there is a risk of fetal malformation, but the child is usually infected through the birth canal, so a cesarean section is an option in this case. In addition to the symptoms, herpes simplex virus type 2 IgM antibodies can be used to determine the presence of the presenting infection.
