Varicella, also commonly referred to as “chickenpox”, is an acute and highly contagious disease. It is caused by primary infection with the varicella-zoster virus (VZV). Varicella occurs worldwide and in the absence of a vaccination programme, affects nearly every person by mid-adulthood.

VZV is highly transmissible via respiratory droplets or direct contact with characteristic skin lesions of the infected person. Routine vaccination is recommended by the U.S. Centers for Disease Control and Prevention (CDC).
