Abstract
PURPOSE
Human papillomavirus is found in adults and adolescents and is associated with genital warts and cervical cancer. However, it has been detected in girls younger than 10 years old. Currently, there are no prevention methods for this age group, since it is not considered a risk group. The aim of this study was to evaluate the presence of infection and HPV subtype in girls under 9 years old attended at a referral service in the State of Espírito Santo, Brazil.

METHODS
Forty-three girls younger than 9 years old had gynecological brush samples collected from vulval and perineal/anal regions. Viral detection and subtyping were done using polymerase chain reaction, restriction fragment length polymorphism and DNA sequencing. Statistics was performed using Action Stat 3.1.

RESULTS
The mean age of girls was 6.1 years. Sexual activity and abuse were not reported by 95.3%. Family stories showed viral infection in 9.3% of mothers, 4.7% of fathers and 9.3% of caretakers. None of these were related with the children infection. In the only case of mother’s gestational HPV infection, the daughter tested negative. Genital warts and infection were observed in 7% and 13.9% of the patients, respectively. Viral subtypes detected were 6, 11, 38 and 42.

CONCLUSIONS
These results demonstrate the presence of Human papillomavirus infection in girls under 9 years of age. Prevalence studies are needed in order to evaluate a possible alteration in age of vaccination policy. This article is protected by copyright. All rights reserved.
