Many people believe that after having chickenpox in childhood, the virus disappears forever. However, the reality is much more surprising: the virus can remain inside the body for decades without causing symptoms.
At certain times, even when a person feels healthy, that virus can reactivate and cause a condition known as shingles, commonly referred to as herpes zoster.
What few people know is that this condition can appear unexpectedly, even many years after having had chickenpox. Herpes zoster is directly related to the varicella-zoster virus, the same virus responsible for chickenpox.
When a person recovers from that illness, the virus does not completely disappear. Instead, it remains dormant in the nervous system, where it can stay inactive for decades without causing any problems.
Under certain circumstances, the virus can reactivate and manifest again, but this time in the form of shingles. Specialists point out that this reactivation usually occurs when the immune system is weakened.
Factors that may influence this include natural aging, prolonged periods of stress, diseases that affect the immune system, medical treatments that weaken immunity, and intense physical or emotional fatigue.
One of the most interesting aspects of herpes zoster is that the first symptoms are not always obvious.
Before the characteristic rash appears, some people may experience burning or pain in a specific area of the body, a tingling sensation, skin hypersensitivity, and localized discomfort.
When the condition fully develops, it typically presents as a rash with grouped blisters on one side of the body. This happens because the virus reactivates along a specific nerve. That is why the lesions follow a localized pattern instead of appearing all over the body.
A complication many people are unaware of
In most cases, **herpes zoster** progresses well with medical treatment. However, if not detected early, a complication called postherpetic neuralgia may occur.
This is a persistent pain that can continue for months or even years after the rash disappears, affecting the quality of life of those who suffer from it.
Is herpes zoster contagious?
A person with shingles does not directly spread shingles, but they can transmit the varicella-zoster virus to someone who has never had chickenpox or is not vaccinated.
In that case, the exposed person could develop chickenpox, not shingles. For this reason, it is recommended to avoid direct contact with pregnant women, newborns, and people with weakened immune systems.
Herpes zoster shows that some diseases can remain hidden for years before appearing. That’s why paying attention to the body’s signals, taking care of the immune system, and consulting health professionals when unusual symptoms appear can make a big difference.
