Assessing the impact of the Covid-19 pandemic on uptake of HIV treatment in Bandung and Yogyakarta, Indonesia
COVID-19 pandemic known to affect health service deliveries including for HIV care support and treatment. In this retrospective study involving 2,780 people living with HIV (PLHIV), we evaluated impact of COVID-19 pandemic by comparing the proportion of PLHIV linked to care, started antiretroviral therapy (ART), retained in care (within the first 3 months of treatment), and adhered to ART (within the first 3 months of treatment) between the pre-p…
Experiences of risk in Australian hotel quarantine
There are systemic issues with infection control in hotel quarantine, which can be further undermined by individual non-compliance. Risks to safety for those in quarantine can be reduced, both in terms of infection control within hotel quarantine and, in the case of the Northern Territory facility, timely in-person medical care as needed for non-COVID conditions. Systems of infection control need ongoing review to ensure that people entering quar…
Sustaining success
HIVST increases the frequency of HIV testing among gay and bisexual men due, in part, to the practical, psychological, and social benefits it offers. To capitalize fully on these benefits, however, strategies to ensure the availability of highly reliable HIVST are required to sustain benefits beyond the confines of a structured research study
Estimation of scabies prevalence using simplified criteria and mapping procedures in three Pacific and southeast Asian countries
The scabies prevalence estimation using simplified criteria was similar to using the 2020 IACS criteria in high prevalence, tropical countries. The prevalence estimation was lower in the school-based survey in Timor-Leste. Mapping using simplified criteria may be a feasible and effective public health tool to identify priority regions for scabies control. Further work assessing use of simplified criteria for mapping in a field setting should be c…
Acceptability of testing for anorectal sexually transmitted infections and self-collected anal swabs in female sex workers, men who have sex with men and transgender women in Papua New Guinea
This qualitative research is the first study of acceptability of anorectal STI testing and specimen self-collection procedures in PNG, and Pacific Asia more broadly. Our qualitative findings show support for anorectal STI testing including the use of self-collected swabs among key populations in PNG. Study findings informed the inclusion of anorectal STI testing in a large bio-behavioural survey to be used to estimate anorectal STI prevalence amo…
Development of a Risk Algorithm to Better Target STI Testing and Treatment Among Australian Aboriginal and Torres Strait Islander People
Individual and population level impacts of illicit drug use, sexual risk behaviours on sexually transmitted infections among young Aboriginal and Torres Strait Islander people
Illicit drug use in this population is relatively high compared to other similar aged populations in Australia. Illicit drug use was associated with risky sexual behaviours and STI diagnoses among this study population. Developing and implementing effective STI prevention strategies should include not only safe sex messages but also include drug and alcohol harm reduction messages
Injecting risk behaviours following treatment for hepatitis C virus infection among people who inject drugs
Building social currency with foreskin cuts
BACKGROUND: Recent research as part of a multi-disciplinary investigation on the acceptability and impact of male circumcision for HIV prevention in Papua New Guinea (PNG) has shown that health workers (HWs) undertake unauthorized forms of penile cutting practices in public health facilities or in community settings, at times within a traditional context. Participation in these activities shares common features with coping mechanisms, strategies …
Ethics of ARV Based Prevention
Published data show that new HIV prevention strategies including treatment‐as‐prevention and pre‐exposure prophylaxis ( PrEP ) using oral antiretroviral drugs ( ARVs ) are highly, but not completely, effective if regimens are taken as directed. Consequently, their implementation may challenge norms around HIV prevention. Specific concerns include the potential for ARV ‐based prevention to reframe responsibility, erode beneficial sexual norms and …
Why Women Object to Male Circumcision to Prevent HIV in a Moderate-Prevalence Setting
Adult male circumcision has been shown to reduce the transmission of HIV. Women's acceptability of male circumcision is important in Papua New Guinea's preparedness to introduce male circumcision, and in ethical considerations of its use as a biomedical technology for HIV prevention. We conducted 21 focus group discussions and 18 in-depth interviews with women in all four regions of Papua New Guinea. The majority of women objected to the introduc…
More than just a cut
BACKGROUND: Male circumcision (MC) has been shown to reduce vaginal transmission of HIV to men. While community acceptability is important in a countries preparedness to introduce MC, it is equally important to map contemporary MC and other penile cutting practices, and the socio-cultural dimensions underpinning these practices. METHODS: A total of 482 men and women (n = 276 and n = 210, respectively) participated in 82 semi-structured and 45 foc…
"Now we are in a different time; various bad diseases have come." understanding men's acceptability of male circumcision for HIV prevention in a moderate prevalence setting
This is one of the first community-based MC acceptability studies conducted in a moderate prevalence setting outside of Africa. Research findings from this study suggest that a future MC program for HIV prevention would be widely accepted by men in PNG
Using population attributable risk to choose HIV prevention strategies in men who have sex with men
Our analysis has found that although UAI with an HIV-positive sexual partner is a relatively low-prevalence behaviour (reported by 5% of men), if this behaviour was not present in the population, the number of infections would be reduced by one third. No other single behaviour or sexually transmissible infections contributes to a greater proportion of infections and HIV-related healthcare costs
Unprotected anal intercourse, risk reduction behaviours, and subsequent HIV infection in a cohort of homosexual men
OBJECTIVE: A range of risk reduction behaviours in which homosexual men practise unprotected anal intercourse (UAI) has been described. We aimed to assess the extent of any reduction in HIV risk associated with these behaviours. DESIGN: A prospective cohort study of HIV-negative homosexual men in Sydney, Australia. METHODS: Men were followed up with 6-monthly detailed behavioural interviews and annual testing for HIV. The four risk reduction beha…

Recruitment and follow-up of injecting drug users in the setting of early hepatitis C treatment
Public opinion towards supervised injecting centres and the Sydney Medically Supervised Injecting Centre
Effectiveness of needle-exchange programmes for prevention of HIV infection
HIV-1 Infection among Female Commercial Sex Workers in Rural Thailand
A retrospective study of 821 commercial sex workers attending a sexually transmitted disease (STD) clinic in northern Thailands Chiang Rai Province from 1989 to 1993 revealed an explosive epidemic of human immunodeficiency virus (HIV). The overall seroprevalence among the 556 women for whom antibody tests were available was 52.3%. However a dramatic increase in HIV-1 seroprevalence occurred from 1989 (29.3%) to 1990 (54.1%) followed by a leveling…
