High prevalence of pre-treatment HIV drug resistance in Papua New Guinea: findings from the first nationally representative pre-treatment HIV drug resistance study

Local Pathways of "Serodiscordant Couples": Unpacking a Global HIV Population Category in Papua New Guinea

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.

Antimicrobial Resistance in Papua New Guinea: A Narrative Scoping Review

Antimicrobial-resistant bacterial infections are a known threat to the public health of low-income countries and are undercharacterized in Papua New Guinea. A scoping literature review of scientific peer-reviewed publications on antimicrobial resistance in Papua New Guinea was conducted, and their results were summarized. Many of the available data on resistant bacteria in Papua New Guinea have come from Port Moresby and Goroka and have been focused on Staphylococcus aureus, as well as important pediatric pathogens such as Streptococcus pneumoniae and Haemophilus influenzae. Progressive resistance to the commonly used antibiotics penicillin and chloramphenicol among most clinically important bacterial pathogens has prompted healthcare workers to adopt expensive broad-spectrum antibiotics. There is already evidence of resistance to newly adopted antibiotics among several Gram-negative organisms. Drivers of antimicrobial resistance in Papua New Guinea include a high burden of infectious diseases, inappropriate antibiotic prescription practices, poor regulation of antibiotics, incomplete adherence, substandard drug quality, and overcrowding of healthcare facilities. There is a lack of information on antimicrobial resistance among priority pathogens and from several important regions of Papua New Guinea.
