Causes of Chickenpox

The varicella-zoster virus causes the chickenpox infection. Most cases occur through contact with an infected person. The virus may be contagious several days before blisters appear, and it remains contagious until all blisters have crusted over.

Immune Cells Involved in Immune Response

T cell-mediated immunity is an immune cell involved in the response. It is detected within 1-2 weeks after appearance of rash. T cell-mediated immunity consists of both CD4 and CD8 effector and memory T cells. T cell-mediated immunity is essential for recovery from varicella (chickenpox).

VZV-specific humoral and cellular immune is another immune cell, involved in the response, that you get from the varicella (chickenpox) disease. The memory cell responses that develop during varicella(chickenpox) or after vaccination contribute to protection following re-exposure to VZV (varicella-zoster virus ).
