RESUMO
OBJECTIVES: The purpose of this study was to assess the prevalence of HSV-1 and HSV-2 in sexually active women who participated in the cervical cancer screening program in Natal, Brazil. STUDY DESIGN: The study included 261 sexually active women resident in the metropolitan area of Natal, Brazil and attending a public clinic for cervical screening. From each participant, a sample of exfoliated uterine cervical cells was collected, using a cytobrush which was conditioned in a tube containing a preserving solution (PBS+vancomycin+nystatin) and sent to a laboratory where it was processed for DNA extraction. The samples were analyzed for the presence of HSV-1 and HSV-2 DNA in separate reactions by PCRs using specific primers. RESULTS: HSV-1 in genital infection is four times more prevalent than HSV-2 in the population analyzed. The highest prevalence rates for both viruses were found in women aged 31-39years. We did not observe any association between the presence of both virus serotypes and socio-demographic characteristics in the population studied, nor with some classical risk factors for sexually transmitted diseases. CONCLUSIONS: HSV-1 was the major cause of genital infection by Herpes simplex virus in the women included in this study. No association was found between HSV infection and the socio-demographic characteristics or some classical risk factors for sexually transmitted diseases.
