People who have had chickenpox usually do not get chickenpox again; however, some patients who had chickenpox as children may develop shingles as adults due to poor body immunity and other reasons. Chickenpox is a self-limiting disease that occurs in spring and winter, and is common in children between the ages of 2 and 6. It is a self-limiting disease with a high degree of contagiousness. The body can acquire long-lasting immunity after contracting chickenpox, and the possibility of re-infection with chickenpox is extremely low, and it usually does not get chickenpox again for life. However, a small number of patients infected with varicella-zoster virus, although the chickenpox cured, but the virus still latent in the body ganglion, in adulthood when the body’s immunity declined can appear herpes zoster. Because chickenpox is extremely infectious, prompt isolation of patients with chickenpox is usually recommended. Patients need to change their clothes regularly and get adequate hydration and vitamins.
