In developing countries, cervical cancer is the most common cause of cancer related to mortality in women. But the epidemiology of human papillomavirus (HPV) in different areas of Bangladesh is largely unknown both in risk groups and in the general population. The objective of the present study was to determine the risk factors associated with having HPV and the prevalence of high-risk HPV types among women with highrisk behaviour and to assess its potential impact on preventive strategies as the sex workers are at increased risk for sexually transmitted infections (STI), HPV and hence cervical cancer. Cervical swab from 293 sex workers in Dhaka City between August and September 2003 and between February 2005 and May 2006 were screened for HPV DNA using an HPV short fragment (E6) polymerase chain reaction (PCR) based assay. HPV positive samples were genotyped with nested multiplex polymerase chain reaction (NMPCR) for the highrisk types. The overall HPV prevalence in sex workers was 75.8%, whereas for the high risk type it was 49.8%. Prevalence of single genotype and multiple types of HPV was 33.1 and 16.7% respectively. The most prevalent high-risk HPV types, in order of prevalence rate, were HPV16, HPV18, HPV58, HPV45, HPV31 and HPV33. Both HPV 16 and HPV 18 were present in 21% of the cases. Targeting HPV 16 and 18 with prophylactic vaccines could possibly have an important impact on the incidence of invasive cervical carcinoma in this group of women. Primary prevention and cervical cancer screening programmes should be optimized more and run yearly among the general population. It is proposed to screen sex workers when they enter prostitution regardless of their age.

Abstract Context.—Human papillomaviruses (HPVs) play an important role in the etiology of squamous cell carcinoma of the uterine cervix. The possible role of the male urogenital tract as a reservoir of HPV infection is not fully understood. We inferred from our previous observation of HPV-31 in epididymal tissue in a case of chronic epididymitis that HPV might be commonly present in cases of epididymitis caused by sexually transmitted pathogens. Objective.—To assess the presence of HPV in the epididymis and ductus deferens in nontuberculous epididymitis. Design.—Epididymal samples obtained from 17 patients and epididymal and ductus deferens samples from 5 patients surgically treated for nontuberculous epididymitis were analyzed by nested polymerase chain reaction for the presence of HPV DNA. In positive samples, the HPV type was determined by DNA sequencing. Setting.—Tertiary-care academic hospital and national reference laboratory for papillomaviruses. Results.—Low-risk HPV type 6 and high-risk HPV types 16, 33, 35, 55, and 73 were detected in 7 patients (31%). Neither koilocytes nor dysplastic changes were found in the epididymis and ductus deferens. Conclusion.—Low-risk and high-risk HPV types were detected in the epididymis and ductus deferens of patients with nontuberculous epididymitis. The infection was not accompanied by koilocytic atypia or dysplasia. Our findings support the hypothesis that the male urogenital tract serves as a reservoir of HPV infection.
