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. From 2004 to 2012 hospital discharge of varicella were 17 398, of which 4.6% had meningoecephalitis, 2.5% pneumonia and 18% other complications. For herpes zoster 7 042 discharges, mostly affected were patients 65 years or older, 1.3:1 the woman-man relationship. Main complications were: neuralgia (11%), eye involvement (7%), meningoencephalitis (5.4%), disseminated disease (2.8%) and others (5.4%); hospital stay was between 6.4 and 13.3 days.

Conclusions:

Data is consistent with that of the literature in other countries. The role of vaccination to prevent infection in children and adults is discussed.
