Risk Factor: Immune System-Related Diseases
The immune system can be compromised by various factors, including aging, autoimmune disorders, and chronic conditions. Individuals who have HIV, AIDS, or cancer are particularly vulnerable to developing shingles. Even if a person already carries the dormant varicella-zoster virus, it may reactivate and cause shingles when their immune system is weakened. Therefore, simply avoiding contact with individuals who have an active shingles infection may not be sufficient to prevent its occurrence.
Risk Factor: Immune System Suppression Medication
When it comes to autoimmune disorders, the immune system tends to overreact, leading to various symptoms. To alleviate these symptoms, individuals with such conditions often receive medication that suppresses their immune system. However, while this approach may provide relief, it also comes with an increased risk: the dormant shingles virus can resurface as a result of immune system suppression. Similarly, individuals taking drugs to prevent organ rejection after a transplant are also more susceptible to developing shingles.
