Hepatitis B (HBV) is a major cause of global morbidity and mortality, and the leading cause of liver cancer worldwide. Significant advances have recently been made toward the development of a finite HBV treatment that achieves permanent loss of HBsAg and HBV DNA (so-called “HBV cure”), which could provide the means to eliminate HBV as a public health threat. However, the HBV cure is just one step toward achieving WHO HBV elimination targets by 2030, and much work must be done now to prepare for the successful implementation of the HBV cure. In this review, we describe the required steps to rapidly scale-up future HBV cure equitably. We present key actions required for successful HBV cure implementation, integrated within the World Health Organization (WHO) Global Health Sector Strategy (GHSS) 2022–2030 framework. Finally, we highlight what can be done now to progress toward the 2030 HBV elimination targets using available tools to ensure that we are preparing, but not waiting, for the cure.

Chronic hepatitis B (CHB) is a significant global health challenge given an increasing morbidity and inadequate public health response, Migrant populations are primarily affected by CHB in industrialised countries, and while more than 7% of Australians with CHB were born in Africa or the Middle East, little is known of their awareness or knowledge of viral hepatitis and its impact. This qualitative study, using semi-structured interviews with Assyrian and Arabic community leaders and focus groups (FG) with 66 community members sought to identify hepatitis and liver cancer knowledge and awareness among local Arabic and Assyrian-speaking communities in Western Sydney. Interviews were thematically analysed, with findings framing the topics for the FGs which were analysed using a framework analysis. Themes identified across both methods included limited awareness or knowledge of viral hepatitis or liver cancer, stigma associated with both conditions, variable levels of health literacy and trust in medical practitioners, and fear that receiving “bad news” would deter people from seeking care. Preferred sources of health information were family doctors, family members, the internet and the ethnic media. The study gave valuable information for the design of an educational program and provided useful information for the planning of culturally appropriate hepatitis screening and treatment services for these communities.

Aboriginal and Torres Strait Islander peoples are disproportionately affected by hepatitis C, an infection that is curable with direct acting antivirals (DAAs). The Australian Government funded access to DAAs from March 2016 for all people with hepatitis C, with primary care physicians, along with clinical specialists, permitted to prescribe these treatments. The Victorian Aboriginal Health Service, in recognising the effect of liver disease from viral hepatitis within their community, and of the increased availability to DAAs, established a Liver Clinic to facilitate access to treatment for people attending the service. This study conducted semi-structured interviews to document the health service provider perspectives on the barriers and enablers to treatment; explored patients’ experiences of hepatitis C treatment and cure; and sought to identify possible health system-level changes to facilitate increased access and uptake of treatment by Aboriginal people. The study found the success of the clinic was supported by the multidisciplinary and accessible nature of the health service, and the relationships built over time between clinic staff and people with, or at risk of, hepatitis C. For those treated, the individual effect of the cure not only eliminated the hepatitis C virus, but reduced shame and increased broader social participation.

This paper argues that blood-borne viruses are relationally embodied, providing an alternative ontology to the individualising tendencies in medical science, and a more inclusive analysis of serodiscordance (mixed infection status) than the literature's focus on transmission risk in couples. We know little about the wider world of significant relationships in the lives of those with blood-borne viruses. People with HIV and hepatitis C are in a mixed-status relationship not just with intimate partners, but with other family members too. Drawing on qualitative interviews and phenomenological theory, we make the case that families (broadly defined) matter in the context of stigmatised, transmissible infections in ways that extend beyond individual bodies and beyond the usual preoccupation with risk. Despite recent advances in the treatment of blood-borne viruses, our study shows that these infections continue to be experienced and negotiated through embodied connections to significant others, made meaningful through culturally situated understandings and expectations regarding kinship, affinity, love, shared history and obligations. Our findings encourage broader recognition of these viral infections as intercorporeal phenomena, with families intimately entangled in co-creating the meanings and experiences of disease.

Hepatitis B is a significant global health issue where the 296 million people estimated to live with the infection risk liver disease or cancer without clinical intervention. The World Health Organization has committed to eliminating viral hepatitis as a public health threat by 2030, with future curative hepatitis B interventions potentially revolutionizing public health responses to hepatitis B, and being essential for viral hepatitis elimination. Understanding the social and public health implications of any cure is imperative for its successful implementation. This exploratory research, using semi-structured qualitative interviews with a broad range of professional stakeholders identifies the public health elements needed to ensure that a hepatitis B cure can be accessed by all people with hepatitis B. Issues highlighted by the experience of hepatitis C cure access include preparatory work to reorientate policy settings, develop resourcing options, and the appropriateness of health service delivery models. While the form and complexity of curative hepatitis B interventions are to be determined, addressing current disparities in cascade of care figures is imperative with implementation models needing to respond to the cultural contexts, social implications, and health needs of people with hepatitis B, with cure endpoints and discourse being contested.

Hepatitis B is a chronic condition, primarily associated with hepatitis B viral infection in early life. The failure of prevention and appropriate management can lead to subsequent liver cirrhosis and cancer. Hepatitis B most commonly affects people born in Asia and Sub-Saharan Africa and their global diasporas. The physical, psychological, and social impacts of hepatitis B are strongly influenced by sex and gender. Inequities in access to timely, sensitive diagnosis and effective management arise from interactions between structural inequalities related to race, ethnicity, Indigenous/settler status, class, and geography. The biomedical response to hepatitis B has led to advances in prevention, diagnosis, and treatment, but many affected communities have explanatory health belief models that differ from that of biomedicine. We argue that an intersectional approach, led by affected people and communities, can integrate biomedicine with the lived experience and social context that give purpose to and shape all personal, communal, clinical, and public health responses to hepatitis B. This approach has the potential to enable a consciously equitable, effective response to the biopsychosocial complexities of hepatitis B, improve the health and wellbeing of people living with hepatitis B, and reduce hepatitis B-associated mortality.
