What Is Shingles? 

What is shingles? Shingles is a viral infection that appears in the form of a streak of blisters mostly on the either side of the trunk of the body. The blisters caused by shingles are rashes that cause a lot of itching, irritation and pain. The virus that causes shingles is the varicella-zoster virus the same one that causes chickenpox. Once it has caused chickenpox the virus remains dormant in the body around brain and spinal cords’ nerve tissues. It reactivates after years to cause shingles which is not life threatening yet causes a lot of pain, aching and agony. The chances of developing shingles are greatly reduced by vaccination and if shingles treatment is started as soon as possible.

Causes of Shingles

Cuause is the root of shingles and that where we get start with "what is shingles".

1. Causes

Shingles is caused by the same virus which causes chickenpox. Once your body has recovered from chickenpox, the virus can reach and remain inactive in the nerve tissues for years. The virus can become mobile again for any number of reasons and travel from the nervous system to the skin to cause shingles. Since shingles is most common in old people and those with a weakened immune system, the cause of reactivation of virus may be low immunity.

2. Precaution: It Is Contagious

A person who has a shingles infection can pass on the varicella-zoster virus that causes shingles to other people who do not have immunization against the virus. The person who receives the virus would not get shingles rather he would get chickenpox which is threatening for some people. The shingles virus spread through the boils and blisters of shingles usually by direct physical contact. So you must avoid having physical touching with newborn babies, pregnant women and people with fragile immune system until your shingles sores and blisters have not healed.

Symptoms of Shingles

Knowing "what is shingles" should never overlook what it feels like to have shingles. The first sign of shingles in most patients is the pain in the area where the shingles virus has caused infection. In some shingles patients, the pain is the only thing that appears and they do not develop any blisters. In most other patients the symptoms followed by the stabbing and burning pain are:

  • Rashes and blisters which are formed a few days after the pain
  • Itching in the rashes
  • Fluids come out as the rashes and sores break open

  • Your age is more than 65. At this age the chances of developing additional complications are greater.
  • The blisters and sores cause a lot of pain and cover an extensive area of the body.
  • Your immune system or the immune system of someone in your family is weak. This may be caused by immunosuppressant medications, cancer or an illness.

Risk Factors of Shingles

  • The risk of developing shingles is greater if you are more than 50 years old.
  • Stress or a sudden physical injury can also cause the chickenpox virus to get reactive and cause shingles.
  • Cancer as well as treatment for cancer can put your body to a greater risk of developing a shingles infection.
  • A weak immune system is the most probable cause of the varicella-zoster virus becoming active again to cause shingles. Illnesses like diabetes and HIV increase the risk.
