Shingles is an infection caused by the varicella – zoster virus, the same virus that causes chicken pox. This virus can survive in your nervous system for years after the chicken pox infection is over and reactivate as shingles.

Shingles skin disease, also known as herpes zoster, often occurs in people over 50 years old. This disease is very rare in children, but if it occurs, it can cause deep and painful wounds. In most cases, zona will resolve within 2 to 3 weeks. Shingles rarely occurs more than once in a person, but according to the Centers for Disease Control and Prevention (CDC), nearly one in three people in the United States will develop it in their lifetime.

What is shingles?

Shingles is a viral infection that affects the nerve and the surrounding skin in the form of painful rashes. This disease is caused by the Varicella Zoster virus, the same silenced chicken pox virus.

For the first time, this virus appears in the form of chicken pox disease, and after complete recovery in nerve cells, it remains silent for many years and becomes active again in the form of shingles. Zona rash starts as a bunch of small bumps that will be different from the surrounding skin. These blisters appear pink, gray, purple, or brown on dark skin, but appear as red bumps on lighter skin.

Which part of the body does shingles affect?
The bumps of this disease turn into fluid-filled blisters after a few days. Usually, after 7 to 10 days, these blisters dry up and become scaly. In general, unlike chicken pox, which spreads in all areas of the body, shingles will mostly affect the upper half of the body. Blisters and zona can appear in areas that have nerve fibers such as the abdomen, neck, chest, and back.

What are the risk factors for shingles?

Age more than 50 years
Extreme stress and anxiety
Reduction of the body’s defense power with cancer or HIV disease
Long-term use of certain immuno suppressive drugs such as steroids
Not being vaccinated for chicken pox in childhood or adulthood
Weakening of the body’s immune system due to chemotherapy or radiation therapy
Complications of herpes zoster (shingles)

Rare and serious complications of zona include:

Brain inflammation or facial paralysis due to the effect of the disease on certain nerves (Ramsey Hunt syndrome)
Eye problems and vision loss
Feeling pain (due to the involvement of the body’s nerves, you feel pain for a long time after complete recovery.)
Bacterial infections with redness, swelling and burning sensation of the skin
Hearing loss or severe pain in one ear
Dizziness or loss of taste

Is shingles dangerous?

In most cases, shingles is not dangerous and does not cause serious damage. except when blistering rashes appear in sensitive areas of the face. Dangerous types of shingles include the following:

face shingles
Sometimes skin rashes appear on one side of the face. If the place where they are created is close to the ear, it can cause an infection. The most important side effects of this type of shingles are hearing loss, balance disorders, and weakness in facial muscles.

On the other hand, shingles inside the mouth can be very painful. It may make eating difficult and affect the sense of taste. A shingles rash on the scalp can cause sensitivity when combing and can lead to permanent bald spots if left untreated.

eye shingles
In this type of disease, blistered rashes usually appear around the eyelids, forehead, and sometimes on the tip or side of the nose. Symptoms such as a feeling of needles or throbbing in the eye, redness, tearing, swelling and blurred vision are complications of eye shingles.

After the rash clears, you may still feel pain in your eye due to nerve damage. In most people, this pain will eventually get better. If left untreated, shingles can lead to serious problems such as long-term vision loss and permanent scarring from corneal swelling.

What are the ways of transmission of zona ?

The varicella-zoster virus, which causes shingles, is not transmitted through the air. The only way to transmit this virus is direct contact with the discharge from the blisters of a person with shingles. In this case, you will not get zona, but you may get chicken pox.


Doctors usually prescribe anti – viral, anti – histamine and anti – inflammatory drugs to treat zona.

Prevention of zona

The best way to prevent it is to get vaccinated against the varicella zoster virus. All children should receive two doses of the chickenpox vaccine, also known as varicella immunization. Adults who have never had chicken pox should also get this vaccine, especially after the age of 50. On the other hand, the chicken pox vaccine before pregnancy is very important to protect the mother and fetus.
