Causes, Symptoms, and Prevention of Shingles

Shingles is a disease caused by the varicella-zoster virus and occurs mainly in middle-aged and older adults whose immune systems have weakened. This virus lies dormant in the nervous tissue of people who had chickenpox in childhood, then becomes active when the immune system weakens, causing shingles. Shingles can be managed through prevention and appropriate treatment, so it should be handled carefully.

The main symptoms of shingles include pain along the nerve pathways, along with a rash and blisters on the skin. These rashes and blisters appear concentrated on only one side of a specific part of the body and may be accompanied by itching. In the early stage, pain occurs first, and skin changes begin to appear a few days later.

The cause of shingles is mainly the varicella-zoster virus, which becomes active when the immune system is weakened. Weakening of the immune system can be triggered by various factors such as aging, stress, certain illnesses, or treatments. Therefore, it is important to maintain healthy lifestyle habits and strengthen the immune system.

Shingles can be prevented through vaccination. The shingles vaccine reduces the risk of developing shingles and, even if it does occur, lowers the severity of symptoms. It is usually recommended for adults aged 50 and older, but the age at which vaccination is needed may vary depending on an individual's health condition.

Treatment for shingles focuses on reducing symptoms and preventing complications. It is more effective when diagnosed early and treatment is started sooner, so if you suspect early symptoms of shingles, you should visit a medical facility immediately. Treatment for shingles may include antiviral medications, pain control medications, and procedures to relieve symptoms.

Shingles is contagious in the early stage of infection, so close contact with other people should be avoided until all blisters have turned into scabs. In particular, it is important to avoid contact with people who have weakened immune systems, pregnant women, and children who have not yet had chickenpox.

Maintaining healthy lifestyle habits and regularly seeing a doctor are effective ways to strengthen the immune system and reduce the risk of shingles. It is also important to receive the shingles vaccine to protect not only yourself but also those around you from shingles.
