Following implementation of the one-dose varicella vaccination program in the United States in 1995, varicella vaccination coverage has steadily increased and the number of varicella cases has decreased. However, despite the increasing use of varicella vaccine, outbreaks of varicella have continued to occur, even in settings with high vaccination coverage. Thus, in June 2006, a second dose of varicella vaccine was added to the routine childhood vaccination program to assist, in part, with outbreak prevention and control.
To improve existing knowledge about the epidemiology of varicella and to have a basis for refining varicella vaccination policy, it is important to monitor and investigate varicella outbreaks. These guidelines for the control and investigation of such outbreaks were developed by the Centers for Disease Control and Prevention’s (CDC’s) National Center for Immunization and Respiratory Diseases (NCIRD) with input from state and local public health departments. Public health officials should implement appropriate responses to reports of varicella cases to determine if an outbreak exists and, if so, to evaluate its scope and implement control measures appropriate to the outbreak setting.
