chickenpox


chickenpox

Contagious viral disease producing itchy blisters. It usually occurs in epidemics among young children, causes a low fever, and runs a mild course, leaving patients immune. The blisters can scar if scratched. The virus that causes chickenpox (varicella-zoster virus) can reactivate years later, causing shingles. Zoster immune globulin (ZIG) can prevent chickenpox in children with leukemia or immunodeficiency disorders who are exposed to the virus. A vaccine has also been developed.
