Shingles does not normally recur and may only recur again if the immune system is extremely low. Herpes zoster is a relatively common skin disease associated with varicella zoster virus infection. Herpes zoster can be cured in a short period of time after active antiviral and nerve nutritional treatment, and after healing, it can obtain a relatively long-lasting immunity, so it will not recur under normal circumstances. In immunocompromised people, the symptoms of shingles are more severe and last longer. In a very small number of immunocompromised people, under the influence of some external factors, the virus latent in the body will be activated again and multiply, thus leading to the recurrence of shingles. The main key to preventing the recurrence of herpes zoster lies in strengthening the body’s immunity, and it is recommended that patients visit the hospital in time and under the guidance of the doctor to carry out standardized treatment.
