Chickenpox is caused by a virus called varicella zoster virus, a member of the herpesvirus family, which also causes shingles. Chickenpox is extremely contagious and can spread by direct contact, droplet transmission and airborne transmission. When someone becomes infected with chickenpox, it appears between 10 and 21 days later. The person becomes contagious 1 to 2 days later the outbreak and remain contagious while blisters are without crust.

The primary invasion by the virus manifests itself in childhood and enters the nerves during the initial phase of chickenpox through sensory endings spreading along nerve trunks to the dorsal root ganglia. In the past the virus remains dormant being able to express distance of time, usually in terms of temporal decay of the state of the organism. The disease assumes a type poliradiculoneurótico with immunoallergic mechanism. There are several theories about the mechanism triggering immune (virus release by the immunogenic material, insertion of viral antigens in cell membranes, immune complex formation, direct action of the virus on the cell membrane) but currently it is still unclear what the immunoallergic actual mechanism.
