AI Article Synopsis
- A study analyzed the prevalence of bacterial vaginosis (BV) and sexually transmitted infections (STIs) among 463 Kenyan women aged 18–34 who participated in a contraceptive study, finding that 72.2% tested positive for either or both.
- Key findings included a 55.6% prevalence of herpes simplex virus type 2 (HSV-2) and significant associations between having STIs/BV and factors like younger age at first sex and multiple sexual partners.
- The researchers suggested implementing combination prevention strategies tailored to women’s varying risk factors to reduce the prevalence of STIs and BV in this population.
Article Abstract
We assessed prevalence and correlates of bacterial vaginosis (BV) and sexually transmitted infections (STIs) including herpes simplex virus type 2 (HSV-2), gonorrhoea (GC), syphilis (SYP), Chlamydia (CT) and HIV among Kenyan women aged 18–34 years who were screened for a contraceptive intravaginal ring study. Women provided demographic, behavioural and medical information, and underwent medical evaluation, including a pelvic exam. We computed crude and adjusted prevalence ratio (aPR) and 95% confidence interval (CI) using log-binomial regression. Of 463 women screened, 457 provided laboratory specimens and were included in the analysis. The median age was 25 years, interquartile range (21–28), and 68.5% had completed primary or lower education. Overall, 72.2% tested positive for any STI or BV. Point prevalence was 55.6, 38.5, 3.9, 2.0, 4.6, and 14.7% for HSV-2, BV, GC, SYP, CT, and HIV, respectively. Co-infection with HSV-2, BV, and HIV occurred in 28 (6.1%) participants. Having ≥1 STI/BV was associated with younger age at first sex (≤13 versus 17–19 years, aPR=1.27, 95% CI 1.07–1.51), history of exchange sex (aPR = 2.05, 95% CI 1.07–3.92), sexual intercourse in the past seven days (aPR = 1.17, 95% CI 1.01–1.36), and older age (30–34 versus 18–24 years, aPR = 1.26, 95% CI 1.06–1.48). STI/BV diagnosis was less likely for women reporting one lifetime sexual partner compared to women with ≥4 lifetime sexual partners (aPR = 0.70, 95% CI 0.54–0.92). Combination prevention approaches (biomedical, behavioural, social, and structural) tailored to women with diverse risk profiles may help mitigate STI/BV prevalence in this setting.

Background: Objectives were to determine the prevalence/incidence of HPV-related dysplasia and clearance/acquisition rates of high-risk HPV (HR-HPV) genotypes in genital mucosa of women-LHIV and oropharyngeal and anal mucosa of PLHIV and to evaluate factors related to HR-HPV infection in oropharyngeal mucosa at 12-months.
Material And Methods: Prospective, longitudinal study with 12-month follow-up, enrolled PLHIV between December 2022 and April 2023. At baseline and 12-months, HIV-related clinical and analytical variables were recorded, oropharyngeal mucosa exudates were taken for polymerase chain reaction (PCR) studies for HPV and other sexually transmitted infections, while anal and female genital samples were self-sampled for HPV detection and genotyping by PCR and thin-layer cytology.
, the most common non-viral sexually transmitted parasite, causes more than 270 million infections annually. The infection's outcome varies greatly depending on different factors that include variation in human immune responses, the vaginal microbiome, and the inherent virulence of the strain. Although the pathogenicity of the different strains depends, at least partially, on differential gene expression of virulence genes; the regulatory mechanisms governing this transcriptional control remain incompletely understood.

Trichomonads parasitize a range of hosts in addition to humans including birds, livestock, and domesticated animals. Recent genetic analysis of trichomonads recovered from columbid birds has provided evidence that these parasite species undergo frequent host-switching, and that a current epoch spillover event from columbids likely gave rise to in humans.

Background: Syphilis is a sexually transmitted infection (STI) that can be prevented and effectively treated; yet it continues to be a cause of morbidity and mortality worldwide. There is a limited understanding of the epidemiology of syphilis in the Middle East and North Africa (MENA) region.
Methods: A systematic review conducted up to April 30, 2024 assessed the prevalence of syphilis and followed PRISMA guidelines, without language and date restrictions.
