Herpes Zoster: Contagion, Symptoms, Cures

ADVERTISEMENT

Shingles is the most popular term for the viral condition of the skin “chickenpox” from the name Herpes Zoster. It is actually the reactivation of the exact skin virus that causes chickenpox, so the name Varicella-Zoster Virus (VZV). Chickenpox is a common occurrence among children while shingles is a problem for people of all ages, particularly those who have a weak immune system. In this article, we will discuss what it is, and as well as the most effective treatment options and cures to treat Herpes Zoster, the vaccine that stops it.

Shingles: Contagion

Shingles – The primary infection or the spread of varicella-zoster (VZV) manifests as chickenpox among children. The primary infection is only experienced once. The virus causes itchy blisters to form, however there is a possibility that the infection will be symptomatic, though very rarely.

What is the reason why it is named Saint Anthony’s Fire?

Why is this illness so similar to chickenpox and called shingles? It’s called St. Anthony’s Fire because it has been the saint who is patronized by fire. fire is a reference to the burning fire of vesicles.

Reactivation of latent infections

Following the initial exposure to the varicella zoster Virus The immune system produces specific antibodies that neutralize the virus. It is nearly completely eradicated.

Antibodies that combat the VZV virus appear within the cells within the immune system however, what remained of the virus is inactive (hidden) within the sensory ganglia of spinal cord or the cranial nerves. The virus may remain there for decades without ever activating itself again, but it isn’t discouraged as it’s continually waiting on the immune system’s ability to fail by weakening it.

If you’ve had shingles at one time but it doesn’t suggest that your varicella virus will not be activated again. The reason is that having suffered shingles doesn’t protect you from reactivations later on.

Are shingles infectious?

Yes, patients suffering from Shingles may infect others but only if they’ve never experienced chickenpox or not been vaccinated for the disease. Infected people will contract chickenpox as it is their first contact to this VZV virus. There isn’t a risk of transmission to others suffering from chickenpox.

The virus is the most infectious during the initial stages of formation of blisters, and after the blisters have disintegrated, they develop into skin lesions. Shingles no longer causes illness when lesions begin heal and scabs begin to form.

Shingles: Causes

The root of shingles is the weakening of immune defenses. Risk factors include years, stress, or any other trigger which can weaken your immune system of the body.

The Varicella-Zoster Virus begins by causing the illness that is known as Varicella that is typically associated with children. As we age, our immune systems fail to remove the virus, which remains hidden within the nerves. In the nerves, VZV virus has been waiting for a chance to activate again, as we age or our immune systems weaken, the virus is reactivated and triggers Shingles.

Initial Symptoms and Complications

What are the first signs of Shingles? Initial symptoms include:

Skin acne that cause red spots, blisters or boils

Itching and pain that is constant

The pain may start before the spots begin to appear. Herpes Zoster mostly affects the body, however in the event that it also affects the facial area, specifically the eye region, you must consult your physician immediately.

The most common problems we encounter are:

 

Ophthalmic herpes Zoster: shingles can also affect the eye and if you don’t immediately take action to seek a particular treatment, your eyesight could be impacted by serious effects.

Postherpetic neuralgia: despite the fact that the skin lesions and spots have gone away completely, severe discomfort persists. It is a severe and disabling condition that is difficult to manage.

Treatment and Vaccine

The treatment for shingles is using anti-inflammatory and analgesic medications. The sooner the medication is given, the less severe the illness will be as well as the duration of the symptoms will be less.

For those who are most at vulnerable, like those over 65, a vaccination is available to prevent the development of shingles as well as associated complications.

Herpes Zoster: Risk Factors

What are the risk factors and the epidemiology for Herpes Zoster? Here are some numbers that will provide you with insight into the frequency of the condition and the probability of being affected;

90% of people suffer from chickenpox. Of these just 10-20% are affected by Herpes Zoster.

Herpes Zoster can be a common illness of the elderly. 2 out of 3 cases have patients over 50.

The people who haven’t been afflicted with chickenpox are unlikely to develop shingles. On the other hand those infected with chickenpox may be at risk of return in the VZV virus and suffering from shingles as they age.

Immune system protects the body however, some risk factors which could trigger shingles vary.

Intensive exposure to sunlight.

Old age.

The diseases include AIDS.

Long-term use of medications like corticosteroids and immunosuppressants (which can suppress your immune system).

Physical and mental stress that is severe.

Chemotherapy and radiotherapy (they may affect the immune system to fight infections).

Shingles: Symptoms

The most prominent sign of shingles is the appearance of itchy, painful skin rash. The rash manifests as the development of flat, red or raised patches which eventually transform into blisters or vesicles. The blisters develop for five days and then turn into pustules after they are filled with pus, and then form scabs.

There are other signs associated with the rash:

Acute, localized pain that is localized and severe. The patients describe the pain as an throbbing stabbing, burning pain that penetrates as if a needle was infiltrating the skin.

Tingling and itching in the local area.

Fever during the phase that causes eruption of vesicles.

A feeling of general depression.

Chills.

Headache.

Intolerance towards light.

Stomach pain.

Sometimes, a pain may be felt on the left side the chest, as if was a cardiac origin, but it’s because of the vesicles.

In rare instances, this disease can also cause motor paralysis within the area of nerves that are which are affected VZV virus.

Prodromal Phase

The rash that appears on the skin caused by Shingles can be preceded by the “prodromal” phase that lasts two to three days. In the prodromal stage, at times, the skin is red, and there’s a mild feeling of numbness. This can trigger the sensation of tingling, and that is the place where the blisters emerge. The prodromal stage can begin up to two weeks prior to the time that the first lesions begin to appear on the skin.

 

Localized abdominal pain that is severe could occur in this phase when the typical VZV lesions don’t appear in the immediate time. In this situation it is recommended to wait for a couple of days.

How long will shingles last?

The infectious disease Herpes Zoster is a chronic condition that lasts for 7-10 days following the time the vesicles appear after which they begin to rupture and form scabs.
