Varicella is caused by the varicella-zoster virus, which is part of the Herpesvirus family. The virus is spread from person to person by direct contact, droplet or airborne spread of vesicle fluid or secretions of the respiratory tract. Varicella is a vaccine-preventable disease that can be fatal. Nationally, 9 case deaths and 11,000 cases of hospitalization due to varicella in adults and children were reported in 2002.
