What is a bubble diagnosis like?

Herpes is a disease caused by infection with the herpes virus. There are many forms of herpes, including herpes simplex virus, including type 1 and type 2, varicella-zoster virus, human cytomegalovirus, human herpes virus, and Epstein-Barr virus, etc. These are all common herpes viruses and are quite harmful to human health, especially genital herpes which often invades multiple organs of the human body.

Varicella-Zoster Symptoms

(1) Herpes zoster

It is an acute infectious skin disease caused by the varicella-zoster virus. 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. The most common sites are the intercostal nerves, cervical nerves, trigeminal nerves and lumbar sacral nerves. It is composed of clustered herpes and is accompanied by pain. The older the age, the more severe the neuralgia, and it can cause postherpetic neuralgia. This disease is more common in adults and is more common in spring and autumn. The incidence rate increases significantly with age.

(2) Varicella-zoster uveitis

It can be congenital or acquired, and the acute retinal necrosis syndrome it causes 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.

(3) Herpes zoster eyelid

Typical lesions are clustered vesicular rashes in the skin distribution areas of the branches of the first trigeminal nerve (frontal nerve, lacrimal nerve and nasociliary nerve) or the third main branch (relatively rare). However, it does not cross the central boundary between the eyelid and the nose, but is limited to one side. It is more common in middle-aged and elderly patients. Recurrence is rare after cure.

(4) Herpes zoster oticus

It was first described by Ramsey Hunt in 1907, so it is also called Ramsey Hunt syndrome or Hunt syndrome, that is, Hunter syndrome, which 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.
