Chickenpox, lesions on the back.Varicella, i.e. chickenpox, is uncommon in adult age because this highly contagious primary infection by Varicella-zoster virus mainly spreads among children before the age of 10 years. The lesions are in different phases of development: vesicles surrounded by red halo, drying, often necrotic vesicles, crusts or red lesions without vesicles. General symptoms with high fever are typical for chickenpox in the adult age.
