What does a positive herpes virus IgG mean?

Herpes is a contagious disease that is usually transmitted through blood or saliva during sexual intercourse. It is highly contagious and herpes is very harmful to human health. It can also easily lead to some physical complications, which have a great impact on physical health. The herpes virus IgG represents a kind of immunoglobulin in the human body. If there is no infection with viral herpes, it will be positive. A positive herpes virus IgG means that there is no virus in the body, but it needs to be observed carefully to avoid infection with the disease later. What does a positive herpes virus IgG mean?

What is herpes virus IgG positive

First, understand the herpes simplex virus. The herpes simplex virus (HSV) exists in the blister scar fluid, saliva and feces of patients, recovering people or healthy carriers. The main way of transmission is direct contact, and it can also be indirectly transmitted through tableware contaminated by saliva. HSV infection has now become the fourth most common infectious disease in the world.

Herpes simplex virus IgG? IgG is produced in the middle and late stages of infection or when the infection has recovered. That is to say, when the infection occurs, igm is produced first (igm is an early infection, usually a current infection), and then disappears after a period of time, and then igg is produced. This antibody disappears very slowly or even does not disappear. Herpes simplex IgG is the antibody produced by a patient who has been infected with herpes simplex.

If the herpes simplex virus IgG is positive and there are no symptoms of herpes, it is because you have been infected with the herpes virus before but are not infected now. This is usually because if you are infected with the virus, the IgG antibody will exist for a long time after the virus disappears.

8 types of herpes viruses

Herpes viruses primarily invade tissues of ectodermal origin, including skin, mucous membranes, and neural tissue. The infection sites and diseases caused are diverse, and there is a tendency for latent infection, posing a serious threat to human health.

1. Herpes simplex virus type 1 (human herpesvirus type 1).

2. Herpes simplex virus type 2 (human herpesvirus type 2).

3. Varicella-zoster virus (human herpesvirus type 3).

4. Epstein-Barr virus (human herpesvirus type 4).

5. Cytomegalovirus (human herpesvirus type 5).

6. Human herpesvirus type 6.

7. Human herpesvirus type 7.

8. Human herpesvirus type 8.

Common manifestations of infection are: ganglion glands, renal lymphoid tissue, lymphoid tissue fever herpes; lip, eye, brain infection; genital herpes chickenpox; herpes zoster mononucleosis, eye, kidney, brain and congenital infection infectious mononucleosis, Burkitt's lymphoma, nasopharyngeal carcinoma, infantile exanthema and some other diseases such as unknown abdominal pain.

feature

It is widely present in nature, causing infections in humans and many animals, mainly invading tissues developed from the ectoderm, such as skin, mucous membranes and nervous tissue.

The word Herpes comes from Greek, meaning crawling like a snake. Herpes virus (HSV) refers to the herpes zoster virus. The herpes viruses in reptiles, fish, frogs and humans are similar in morphology, but their antigenicity, the G+C content in the genomic DNA and the sequence of the viral DNA are all different. The virus particle consists of 162 porous particles arranged in an icosahedral capsid, with a lipid envelope of more than 20 polypeptides on the outside. The viral genome is a linear double-stranded DNA molecule, 140,000 bp long.
