Zoster occurs even in otherwise healthy children. The risk factor is chickenpox infection during infancy with premature immunity. A prospective study of zoster during 17 years from 2001 to 2017 was carried out and compared with the same type of survey between 1990 and 2000 at the department of pediatrics in this university hospital. This study, enrolled 56 subjects (M/F, 30/26), aged 3.9 ± 4.0 years (mean ± SD). The peaks in frequency were 2 and 8 years of age. The dermatome of zoster appeared mostly in thoracic area (55%), followed by the lumbar region (18%). Symptoms included painful itching was found in 77% of the patients. A past history of chickenpox when under one year of age was recognized in 36.4% (12 of 33 zoster). When comparing with the earlier study, the zoster in otherwise healthy children had decreased, and the age of zoster patients had lowered. The possible reason for this was considered to be associated with national immunization of the varicella vaccine to children aged 1 to 3 years. The characteristics of zoster in otherwise healthy children were mild morbidity without postherpetic neuralgia.
