Herpes simplex type 1 IgG positivity is usually indicative of having been infected with the herpes simplex type 1 virus or being in the recovery phase of the infection and the presence of herpes simplex type 1 IgG antibodies in the body at present. Herpes simplex virus is mainly categorized into type 1 and type 2, of which herpes simplex virus type 1 is mainly transmitted by direct contact, often appearing in clusters or scattered blisters on the head, face, mouth, cornea and other parts of the body. After herpes simplex virus infection, IgM antibodies usually appear first, followed by IgG antibodies, which exist in the blood for a relatively long period of time, some up to several years, so a positive test for IgG antibodies in the clinic often suggests that there has been a herpes simplex virus type 1 infection or is in the recovery period of the infection. It is recommended to consult a doctor for timely treatment of herpes simplex virus type 1 infection and use antiviral drugs such as acyclovir under the doctor’s guidance. In addition, rest should be paid attention to and avoid overwork.
