Аннотация
BACKGROUND: In Chile, cervical cancer is the second leading cause of death from malignancy in women. The main causal agent of cervical cancer is the human papillomavirus (HPV). Compared with the general population, sex workers (SW) are at increased risk of acquiring HPV.
AIM: To analyze the prevalence and genotypes of cervical and vaginal HPV in female SW attending a Sexual Control Centre.
METHODS: A cross-sectional study was carried out on 97 women (19-70 years old). Two samples were taken per patient, one from exocervix and the other from vaginal walls. HPV DNA. was identified by polymerase chain reaction (PCR) and genotyping using specific probes for 32 types of HPV.
RESULTS: The overall frequency of HPV was 45%, 41.2% in cervical carrier and 36.1% in vaginal carrier, 32% were co-infected, 63% of HPV were high-risk genotypes. The most frequent high-risk HPV was HPV 66 (12%), HPV 58 (9.3%), followed by HPV 16, HPV 59 and HPV 82 with the same frequency (8% each one). Thirty two (43%) of females were infected with multiple genotypes.
CONCLUSION: HPV is frequent infection among SW. This is the first study in Chile on the prevalence and genotypes of HPV in sex workers.
