Background: Prevalence of HIV in Mozambique among individuals aged 15-49 years is 11.5%. The HIV prevalence is higher in women than in men across the country, peaking at ages 25-29 years and 35-39 years, respectively. In this study, we aimed at determining the prevalence and incidence of HIV, prevalence of Hepatitis B (HBV), and prevalence of syphilis in youths. We also characterized a cohort of youths for future participation in phase I/II HIV vaccine trials.
Methods: The study was conducted at a youth clinic in Maputo Central Hospital from August 2009 to October 2011. Youths of both genders aged 18-24 years (n = 1380) were screened for HIV using a sequential algorithm of two immunochromatographic assays, HBV using an enzyme linked immunosorbant test, and syphilis using a treponemal immunochromatographic strip test. The HIV seronegative participants (n = 1309) were followed-up for 12 months with quarterly study visits. The clinical and behavioral data were collected using structured questionnaires. The HIV seroconversions were confirmed by a molecular assay.
Results: The study population was female dominant (76.8%). All participants had a formal education, with 44.6% studying for technical or higher education degrees. The mean age at sexual debut was 16.6 years (SD: ± 1.74), with 85.6% reporting more than one sexual partner in life. The screening showed the prevalence of HIV, HBV, and syphilis at 5.1% (95% CI: 3.97-6.31), 12.2% (95% CI 10.5%-14.0%), and 0.36% (95% CI 0.15%-0.84%), respectively. The HIV incidence rate was found to be 1.14/100 person years (95% CI: 0.67-1.92). Retention rates were stable throughout the study being 85.1% at the last visit.
Conclusion: Incidence of HIV in this cohort of youths in Maputo was relatively low. Also, the prevalence of HIV and syphilis was lower than the national values in this age group. However, the HBV prevalence was higher than in previous reports in the country.

The rising global incidence of syphilis underscores the risk of transmission through blood transfusions. Treponema pallidum, the pathogen responsible for syphilis, represents a major public health challenge. Accurate detection is essential for controlling the disease, particularly in asymptomatic blood donors.

Background: New indicators of potential human immunodeficiency virus (HIV) transmission are being actively explored. We aim to categorical testing of the viral load (VL) of persons living with HIV (PLWH) in order to explore new indicators to measure the intensity of the epidemic and the effectiveness of the response in the community.
Methods: A dynamic cohort study was conducted in Yining to monitor the VL of all persons living with HIV from 2017 to 2019.

Cervical cancer continues to disproportionately burden women in sub-Saharan Africa, and is the commonest gynecological cancer in Ghana. The Cervical Cancer Prevention and Training Centre (CCPTC), Battor, Ghana spearheaded the Ghana arm of the mPharma 10,000 Women Initiative (mTTWI) between September 2021 and October 2022. The aim of this study was to examine the outcomes of nationwide concurrent screening using high-risk human papillomavirus (hr-HPV) DNA testing and visual inspection methods, as well as factors associated with the screening outcomes.

Objectives: The decennial National Surveys of Sexual Attitudes and Lifestyles (Natsal) provide general population prevalence estimates in Britain for key sexually transmitted infections (STIs) through biosampling. Since methodological choices can impact acceptability and response rates, we evaluated processes for Natsal-4, including face-to-face and remote interview arrangements, non-return of test results and vaginal swab collection in two pilot studies.
Methods: The pilots were conducted during June to August 2021 and February to March 2022.

Background: Chemsex engagement is known to be associated with higher-risk sexual behaviour, HIV and sexually transmitted infection (STI). To reduce HIV infection risk, pre-exposure prophylaxis (PrEP) is increasingly used in the men who have sex with men (MSM) community. This study aims to examine the interrelationship between chemsex engagement and PrEP use in MSM.
