Clinical information about Herpes Zoster:

Herpes Zoster is the medical term used to refer to a type of viral infection caused by the reactivation of dormant VZV (Varicella-Zoster Virus) remnants. VZV is the virus responsible for Chickenpox.

Even if the Chickenpox disappears, it will leave remnants of VZV in its wake. These remnants can reactivate at a certain point in a person’s life. It’s currently not determined what exactly caused these remnants to reactivate, but research points to illnesses, aging, using certain medicines, and being stressed as potential culprits.

When VZV remnants reactivate, it will give rise to skin rashes that are painful and itchy. Some people might even feel burning or tingling sensations in the area of the rash. They can even form blisters!

The rashes resemble patches, strips, or a band wrapping the skin. People commonly refer to these as shingles.

Synonyms include:

Herpes zoster encephalitis
Herpes zoster with meningitis
Conjunctivitis of left eye caused by herpes zoster virus
Conjunctivitis of right eye caused by herpes zoster virus
Herpes zoster iridocyclitis
Herpetic iridocyclitis

Commonly asked questions

Not necessarily. However, if the Herpes Zoster forms blisters, the fluid in these blisters can cause other people who have never had VZV to be infected and develop Chickenpox.

‍

Postherpetic neuralgia is one. This complication occurs once the rashes are gone. It’s characterized by persistent pain in the nerves of the affected area.

It can also cause skin infections.

They will administer antivirals and pain relievers to help reduce the duration of shingles and lessen the pain. They will also likely recommend taking the shingle vaccine to prevent it from reoccurring. The re-emergence of shingles in a person is rare, though.
