[Varicella and herpes zoster: challenges for public health].

Objective: To evaluate the epidemiological behavior of varicella and herpes zoster (HZ) to determine the need of health policies to diminish prevalence and avoid complications.

Materials And Methods: To assess frequency, we analyzed data from the National Information System for Epidemiological Surveillance (SUIVE) from 2000 to 2013; to assess the discharge data of varicella and HZ, we evaluated information from the National System of health information (Sinais).

Results: The average annual cases of chickenpox were 296 733, 57% mostly children under 9 years, most of them from March to May.
