We've all heard about Herpes Zoster Virus (HZV) before but what is it exactly?
If you've had chickenpox as a kid, chances are you've developed antibodies to the virus.
So you won't get infected with chickenpox again even if you find yourself exposed to the infection later on.
But did you know that with this exposure, you could be in a much greater risk of acquiring Shingles?
Shingles is another term for an HZV infection. It is an infection of the skin characterized primarily by skin rashes that appear as blisters and are commonly painful.
It occurs when a dormant ("sleeping") chicken pox infection becomes activated in an older adult.
Here are the essential things that you need to know about the HZV virus:
In essential, HZV (or shingles) is simply a painful skin rash that usually manifests in a strip or a band on one particular site of the body like the face, the shoulders, and the upper or lower limbs. It is readily transmitted through skin-to-skin contact.
(Raised red bumps and blisters caused by the Herpes Zoster Virus)
The same virus that causes chicken pox in kids or young adults, which is the Varicella Zoster Virus, also causes HZV or Shingles. This means that if you already had a case of chicken pox before, then the chances of you acquiring herpes zoster is increased.
Some causes of Shingles also include certain types of medications that may trigger the virus to "wake up". The process in which the virus is reactivated in this way still need more research to completely explain the phenomenon.
In much the same way that HSV 1 and HSV 2 remain dormant for a time inside the human body after an initial infection, the Varicella Zoster Virus (VZV) is also able to remain dormant in the nerve endings of the human body. This is why some older adults have higher chances of acquiring Shingles if they get exposed to the virus again.
HZV is a fairly common infection nowadays, with about 1 in every 4 people tested having the infection at least at one point in their life.
However, a few studies have shown that an increased risk of reinfection can occur among those aged 50 and over.
HZV infection usually manifests on the part of the body that the infected nerve supplies. This means the virus most commonly affects the abdomen, chest, and upper portions of the face.
There are only two primary HZV shingles symptoms: pain and rashes.
A typical HZV infection episode typically lasts about 2-4 weeks after onset.
Yes! In fact, if you haven’t been infected with chickenpox before, then you can catch chickenpox from a person infected with HZV. The rashes associated with the virus are contagious until such time that they are all dried up (and form scabs).
Like most infections, there are a few factors that can markedly increase a person’s likelihood of contracting the virus. Here are some of them:
If you think you have these signs and Herpes Zoster symptoms, best is to visit your family doctor and have it confirmed with an appropriate lab test and diagnosis.
If you are still unsure about your symptoms:
With proper care and management, most people with Shingles will definitely get better and are unlikely to have another outbreak again.
