Chickenpox is a highly contagious disease contracted by the inhalation of aerosolized nasopharyngeal secretions or through direct contact with the vesicles from an infected host. Chicken pox has an incubation period of 10-21 days. Viral proliferation occurs in regional lymph nodes of the upper respiratory tract leading to viremia. Viremia is characterized by diffuse viral invasion of capillary endothelial cells and the epidermis. VZV infection of cells of the malpighian layer produces both intercellular and intracellular edema, resulting in the characteristic vesicles.
