Chickenpox is not transmitted a second time. Because a normally immune person who gets chickenpox for the first time can gain lifelong immunity to chickenpox, that is, if he or she is exposed to the varicella-zoster virus again, he or she will not get chickenpox again and will not get shingles again; the body’s immune system has a memory of this virus and is able to clear it. However, after the first chickenpox, the varicella-zoster virus will be latent in the nerve root cells and may become active again and cause infection only when the immunity is low. The infection is not a systemic infection, so it is not called chickenpox, but a localized skin infection called herpes zoster. Therefore, it is only when the body’s immunity is low that the virus becomes active and infects again, and the second contact of the varicella-herpes virus with a person does not give them chickenpox, nor does it give them shingles.
