Sci Rep 2020; 10:7001. [PMID: 32332798 PMCID: PMC7181610 DOI: 10.1038/s41598-020-63882-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Accepted: 04/07/2020] [Indexed: 11/12/2022] Open
Abstract
Human papillomavirus (HPV) types differ by geographic location and the ethnicity of the human host, which may have implications for carcinogenicity. HPV35 is one of the least frequently identified high-risk types in North America and Europe but was the most common high-risk HPV (hrHPV) infection in a cohort in rural Zimbabwe. Whole genome analysis is limited for HPV35; no such studies have been performed in Zimbabwe. Of 648 women in the initial cohort in Zimbabwe, 19 (19/648, 2.9%) tested positive for HPV35, and eight samples were successfully sequenced for HPV35. The maximum number of sequence variants for the whole genome was 58 nucleotides (0.7%) compared to the prototype (58/7879). The maximum number of sequence variants in E6 and E7 was 3 (3/450, 0.7%) 2 (2/300, 0.7%), respectively. These are the first HPV35 whole genome sequences from Zimbabwe, and these data further lend support to the carcinogenicity of HPV35 despite limited sequence heterogeneity. Further studies to determine carcinogenic effects and impact of HPV vaccinations are warranted, especially in sub-Saharan Africa.

Abstract
The objective of this study was to determine the prevalence of human papillomavirus (HPV) among females in the east coast of Spain. A total of 1956 women visiting gynaecology clinics for routine check-ups were included in the study. Swabs were analyzed for HPV DNA by consensus polymerase chain reaction followed by direct sequencing. The overall HPV prevalence was 12.99%. HPV vaccine types 6, 11, 16 and 18 were detected in 6.13% of female participants.

Prevalence and risk factors of sexually transmitted infections and cervical neoplasia in women from a rural area of southern Mozambique. Infect Dis Obstet Gynecol 2010; 2010:609315.

Abstract
There is limited information on the prevalence of sexually transmitted infections and the prevalence of cervical neoplasia in rural sub-Saharan Africa. This study describes the prevalence and the etiology of STIs and the prevalence of cervical neoplasia among women in southern Mozambique. An age-stratified cross-sectional study was performed where 262 women aged 14 to 61 years were recruited at the antenatal clinic (59%), the family-planning clinic (7%), and from the community (34%). At least one active STI was diagnosed in 79% of women. Trichomonas vaginalis was present in 31% of all study participants. The prevalence of Neisseria gonorrhea and Chlamydia trachomatis were 14% and 8%, respectively, and Syphilis was diagnosed in 12% of women. HPV DNA was detected in 40% of women and cervical neoplasia was diagnosed in 12% of all women. Risk factors associated with the presence of some of the STIs were being divorced or widowed, having more than one sexual partner and having the partner living in another area. A higher prevalence was observed in the reproductive age group and some of the STIs were more frequently diagnosed in pregnant women. STI control programs are a priority to reduce the STIs burden, including HIV and cervical neoplasia.
