Epidemiology of severe varicella-zoster virus infection in Spain.
Data of hospitalizations for varicella and herpes zoster in Spain during the 1999-2000 period were obtained from the national surveillance system for hospital data. A total of 3083 hospitalizations for varicella and 6324 for herpes zoster were identified, representing an annual incidence of 4.1 and 8.4 per 100,000 persons per year, respectively.
