What is herpes

Bacteria are everywhere in life. There are many types of bacteria, and the damage to human health is also very different. When eliminating bacteria, you must be careful not to do it arbitrarily, otherwise it will cause a variety of problems. What is herpes? Many people are not very clear about this. It is a disease caused by a virus, which also has some harm to human health.

If you want to fully understand what herpes is, you need to consult about it in detail, so that you can have a good understanding of it before treatment. However, it should be noted that the treatment of this type of disease takes some time.

What is herpes?

Herpes broadly refers to diseases caused by viruses of the herpesviridae family. There are currently eight viruses in this family known to cause human disease, and these viruses are collectively referred to as human herpesviruses. Common ones include varicella-zoster virus and herpes simplex virus. It can invade multiple organs of the human body.

Common diseases

Varicella-zoster virus disease

Herpes zoster is an acute infectious skin disease caused by the varicella-zoster virus. Children who are not immune to the virus develop chickenpox when infected. Some patients become carriers of the virus after being infected but do not develop symptoms. Because the virus is neurotropic, it can remain dormant in the neurons of the dorsal root ganglia of the spinal cord for a long time after infection. When the resistance is low or when you are tired, infected, or have a cold, the virus can grow and multiply again and move along the nerve fibers to the skin, causing severe inflammation of the invaded nerves and skin. The rash is generally unilateral and distributed according to nerve segments, composed of clustered herpes and accompanied by pain; the older the age, the more severe the neuralgia. This disease is more common in adults and is more common in spring and autumn. The incidence rate increases significantly with age.

(1) Varicella-zoster uveitis Varicella-zoster uveitis can be congenital or acquired. The acute retinal necrosis syndrome caused by it has become an important blinding eye disease. The diagnosis is confirmed by isolating and culturing the varicella-zoster virus from infected tissue. Slit lamp examination can reveal anterior uveal lesions; fundus fluorescein angiography can reveal retinal vasculitis and the corresponding characteristic changes of retinal neovascularization and optic discitis.

(2) Herpes zoster eyelids The typical lesions of herpes zoster eyelids are mostly in the skin distribution areas of the first branch of the trigeminal nerve - the branches of the ophthalmic nerve (frontal nerve, lacrimal nerve and nasociliary nerve) or the branches of the third main branch (relatively rare), and clustered vesicular rashes occur. However, it does not cross the central boundary between the eyelid and the nose, but is limited to one side. Herpes zoster is a more serious eyelid disease caused by infection with the varicella-zoster virus. It is more common in middle-aged and elderly patients. Relapse is rare after cure, and the disease provides lifelong immunity.

(3) Herpes zoster oticus Herpes zoster oticus was first described by Ramsey Hunt in 1907, so it is also called Ramsey Hunt syndrome or Hunt syndrome. It is a disease caused by varicella-zoster virus infection. A group of special symptoms caused by herpes virus infection of the geniculate ganglion of the facial nerve, mainly manifested as severe pain in one ear, ear herpes, ipsilateral peripheral facial paralysis, accompanied by hearing and balance disorders, so it is also called geniculate ganglion syndrome.

Through the above introduction, we have explained one by one what herpes is. This type of disease is also divided into different types, and the treatment methods are also different. After discovering that you have such a disease, you should choose the appropriate treatment method according to your own situation. This will be of great help in improving your own disease.
