The herpes zoster virus, commonly known as the varicella-zoster virus, is a member of the herpesvirus family that causes both chickenpox and shingles. After a person recovers from chickenpox, the virus remains dormant in the nerve cells near the spinal cord and is at risk of reactivating later in life, leading to the development of shingles.
Shingles is characterized by a painful rash that typically appears on one side of the body and is accompanied by itching, burning, and tingling sensations. The rash follows the pattern of a dermatome, a specific area of skin that is innervated by a single nerve root, reflecting the localized nature of the virus reactivation. While shingles is more common in older adults and individuals with weakened immune systems, it can also affect younger individuals who have previously had chickenpox.
In recent years, there has been a growing emphasis on the importance of vaccination programs worldwide. Vaccines play a crucial role in preventing diseases and promoting public health. However, there are significant variations in vaccination rates across different regions and populations. While some countries have successfully implemented robust immunization campaigns, others continue to face challenges in achieving high vaccination coverage.
