Airborne transmission of varicella and disseminated HZ has been documented in health care settings . Airborne transmission from localized HZ is rare but has also been documented . Most of the VZV strains collected in the United States are the European (E) genotype (81.5%), followed by the mosaic (M) (15.5%) and Japanese (J) (3%) genotypes. Chickenpox, also known as varicella, is a highly contagious disease caused by the initial infection with varicella zoster virus. The disease results in a characteristic skin rash that forms small, itchy blisters, which eventually scab over.
