Shingles, a viral infection caused by the varicella-zoster virus, is notorious for its excruciating rash. Unlike most viruses, the shingles virus can lie dormant for many years without showing any symptoms. However, one of the initial indicators of its reactivation is a sensation of burning, itching, or tingling in the affected area.
Various factors can trigger the reemergence of the dormant shingles virus, particularly in older adults. It is important to explore these potential causes in order to better understand this condition.
Risk Factor: History of Chicken Pox
Individuals who have previously experienced chickenpox carry the virus responsible for shingles. This virus remains inactive in the nerve tissue until it is triggered to reactivate. The virus is categorized as opportunistic, meaning it takes advantage of a weakened immune system caused by other factors. It is important to note that if someone has never had chickenpox and they become infected with the varicella-zoster virus, they will develop chickenpox, regardless of their age.
Cause: Transmission of the Varicella-Zoster Virus from Shingles
When an individual has active shingles, they have the potential to transmit the varicella-zoster virus to someone who lacks immunity to chickenpox. This can occur in individuals who have never had chickenpox or have not received the chickenpox vaccine. It is important to note that not everyone who is exposed to the shingles virus will immediately display symptoms. Some individuals may initially develop chickenpox, while others may develop shingles at a later time.
The transmission of the varicella-zoster virus is primarily through direct contact with the oozing and open sores of the shingles rash. It is crucial to understand that a person with shingles can remain contagious until all the sores have completely crusted over.
