Sex Health

April 2024

Central Clinical School, Monash University, Melbourne, Vic., Australia; and Melbourne Sexual Health Centre, Melbourne, Vic., Australia; and Faculty of Infectious and Tropical Diseases, London School of Hygiene and Tropical Medicine, London, UK.

Background Australia imposes restrictions for people living with HIV (PLHIV) applying for permanent residency (PR), including spending less than AUD51,000 on medical costs over 10years. Some PLHIV opted for suboptimal and cheaper antiretroviral therapy (ART) regimens to increase their chances of receiving PR. We collated a case series to examine PLHIV on suboptimal ART because of visa issues.

Background: Female sex workers (FSWs) contribute disproportionately to HIV transmission in Uganda, and pre-exposure prophylaxis (PrEP) is effective in preventing HIV among cisgender women. Psychological factors are important for PrEP uptake, but few studies have examined psychosocial changes due to PrEP use in Uganda.

Methods: In 2021, we recruited 524 FSWs in three Trans-African Highway towns and four fishing communities in south-western Uganda.

HIV prevention programs focus on global "key populations" and more localized "priority populations" to ensure effective targeting of interventions. These HIV population categories have been subject to considerable scholarly scrutiny, particularly key populations, with less attention given to critically unpacking priority populations at local levels, for example "serodiscordant couples" (one partner has HIV, but not the other). We examine this population in the context of Papua New Guinea to consider how local configurations, relational pathways, and lived realities of serodiscordant relationships strain the boundaries of this population category and raise intriguing questions about its intersection with contemporary biomedical agendas.

Evaluation of Illumina® COVIDSeq™ as a tool for Omicron SARS-CoV-2 characterisation.

J Virol Methods

December 2023

The Queensland Paediatric Infectious Diseases (QPID) Sakzewski Laboratory, Queensland Children's Hospital, Brisbane, Queensland, Australia; The University of Queensland Centre for Clinical Research (UQCCR), Faculty of Medicine, The University of Queensland, Brisbane, Queensland, Australia; Infectious Diseases Laboratory, Pathology Queensland, Brisbane, Queensland, Australia.

The continued emergence and transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants requires ongoing genetic surveillance to support public health responses. The expansion of reliable next generation sequence (NGS) platforms has enabled the rapid characterisation of the constant emergence of new SARS-CoV-2 variants using nasopharyngeal swab specimens. Several studies have assessed the ability of COVIDSeq to type earlier SARS-CoV-2 strains (pre-Delta) rapidly and successfully, however, there is limited data showing suitability against Omicron variants.

Introduction: Human papillomavirus (HPV) testing is transforming cervical screening globally. The World Health Organization (WHO) now recommends same-day HPV screen-and-treat for primary cervical screening in low- and middle-income countries (LMIC) but there is a lack of evidence on women's lived experience of testing positive for oncogenic HPV and receiving same-day treatment. This study aimed to address this knowledge gap among women participating in a same-day HPV screen-and-treat (HPV S&T) program in Papua New Guinea.

Background: Soil-transmitted helminth (STH) infection is driven by a complex interaction of demographic, socioeconomic and behavioural factors, including those related to water, sanitation and hygiene (WASH). Epidemiological studies that measure both infection and potential risk factors associated with infection help to understand the drivers of transmission in a population and therefore can provide information to optimise STH control programmes.

Methods: During October and November 2019, we conducted a cross-sectional survey of the prevalence and intensity of STH infection and associated risk factors among 7710 primary-school-age children from 64 primary schools across 13 districts in Dak Lak province, Vietnam.

SARS-CoV-2 RT-PCR to Screen for B.1.617.2 (Delta) Variant of Concern.

Diagnostics (Basel)

August 2022

The Queensland Paediatric Infectious Diseases (QPID) Research Group, Queensland Children's Hospital, Brisbane, QLD 4101, Australia.

The continuous transmission and evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has required that diagnostic capabilities be constantly monitored and updated as new variants emerge and prior variants disappear. Although whole genome sequencing provides full characterisation of SARS-CoV-2 directly from patient samples, this has limited throughput and requires sufficient resources. To enhance screening for circulating variants, we designed a rapid in-house RT-PCR assay to target a spike mutation (D950N) in Delta variants, which is not detected in the remaining variants of concern (VOCs).

Men who have sex with men in Uganda are a heterogenous, discriminated population, experiencing high HIV burden, limited access to HIV testing, and low treatment adherence. We contribute to the lack of information about men who have sex with men in rural Uganda by using socio-ecological analyses to examine the social influences shaping their engagement with HIV services. Based on in-depth interviews with 16 men, our findings reveal the inhibitive influence of interpersonal relationships with sexual partners, peers and families, and institutional influences within health service and non-governmental organizational settings.

Background: Timely diagnosis and early initiation of life-saving antiretroviral therapy are critical factors in preventing mortality among HIV-infected infants. However, resource-limited settings experience numerous challenges associated with centralised laboratory-based testing, including low rates of testing, complex sample referral pathways and unacceptably long turnaround times for results. Point-of-care (POC) HIV testing for HIV-exposed infants can enable same-day communication of results and early treatment initiation for HIV-infected infants.
