Differential Association of Hepatocellular Carcinoma Related to Hepatitis B Between Urban and Rural Areas in Africa Using Satellite Spatial Scaling Data. JCO Glob Oncol 2025; 11:e2400543. [PMID: 40184566 PMCID: PMC12004990 DOI: 10.1200/go-24-00543] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2024] [Revised: 01/27/2025] [Accepted: 02/18/2025] [Indexed: 04/06/2025] Open
Abstract
PURPOSE Sub-Saharan Africa carries one of the highest burdens of hepatocellular carcinoma (HCC) in the world, with hepatitis B virus (HBV) as the most common cause. Studies in several regions of the world suggest important cancer differences in rural versus urban settings, but limited studies have been performed in Africa. METHODS We performed a scoping review and pooled analysis of studies on HCC in Africa. Using land use data from the European Space Agency, we calculated the distance in kilometers from each study site to the nearest rural area. Regression models were fit to estimate the association between distance to the nearest rural area and HBV, sex, and weighted mean age. RESULTS Data from 57 studies including 10,907 patients across 36 towns/cities were included in our analysis. Proximity to rural areas was associated with a higher frequency of HBV-associated HCC in assessment of distance both at midpoint and at quartiles after controlling for country: risk ratio (RR) 1.71 (95% CI, 1.52 to 1.93) and RR 1.51 (95% CI, 1.25 to 1.84), respectively. No association was found between sex and proximity to a rural area: RR 1.02 (95% CI, 0.96 to 1.08). The weighted mean age across the four distance quartiles was 50.09, 53.43, 47.98, and 53.35 years with no statistically significant difference found across the quartiles (P = .81). CONCLUSION Individuals living in rural Africa have a higher rate of HBV-related HCC compared with other liver diseases. Increased HBV awareness efforts in these areas should be considered.

Understanding knowledge and media influence on people with hepatitis B in Senegal: a mixed-methods study. BMJ Open 2025; 15:e085453. [PMID: 40132851 PMCID: PMC11934370 DOI: 10.1136/bmjopen-2024-085453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Accepted: 03/11/2025] [Indexed: 03/27/2025] Open
Abstract
OBJECTIVES Public awareness and the dissemination of tailored information to lay populations are essential for highly endemic countries like Senegal to achieve hepatitis B elimination targets by 2030. In Senegal, despite its high prevalence, hepatitis B has not received sufficient attention in health communication campaigns compared with other health issues like HIV. We aimed to explore knowledge and perceptions surrounding hepatitis B virus (HBV), as well as the influence of digital media on the information accessed by individuals living with HBV in Senegal. DESIGN We employed a mixed-methods approach combining qualitative semistructured interviews conducted with people living with HBV enrolled in the Senegalese hepatitis B cohort (SEN-B), with a quantitative content analysis of online news coverage focused on HBV within the online media of Senegal. SETTING A referral University hospital in Dakar, Senegal. PARTICIPANTS 29 individuals aged >18 years presenting with a positive hepatitis B surface antigen (HBsAg) with a median age of 40 years (IQR 27-54), of whom 51.7% were female. OUTCOMES AND ANALYSIS Qualitative interviews were conducted between December 2019 and October 2021, and we employed purposive sampling to select participants enrolled in SEN-B. Thematic analysis facilitated a systematic synthesis of respondents' narratives. All data analyses were performed using Atlas.ti (V.22). For content analysis of online media news collected from September 2019 to May 2022, a structured data extraction form was developed to collect relevant information from the selected online news articles. Data on readers' comments spaces were extracted using an inductive approach and were processed using thematic analyses. The quantitative data issued from content analysis were exported to Stata SE V.17.0 (StataCorp) for statistical analysis. RESULTS We observed a generalised lack of knowledge about HBV among participants, some of whom had never heard of the virus prior to their screening. Incomprehension regarding the disease contributed to feelings of fear and anxiety, leading participants to express various concerns about their personal health status, transmission, cure and treatment(s). The presence of rumours surrounding the disease further underscored the limited awareness of HBV revealing the marginal recognition of HBV as a significant societal concern. In many cases, the absence of effective health communication strategies at the national level resulted in individuals turning to traditional and online media for information, which often intensified their fears and concerns about HBV. An analysis of Senegalese media coverage about HBV included 157 articles published between 2009 and 2022. 55.4% (87/157) of these publications appeared in July, coinciding with World Hepatitis Day, while 65.0% (102/157) focused on general HBV epidemiology and activities led by the National Hepatitis Programme. Online media also served as informal spaces where unaccredited actors within the health sector promoted treatments lacking official verification. Additionally, the reactions' spaces provided a venue for the exchange of information, though without any guarantee of its accuracy. CONCLUSIONS Facilitating collaboration and engagement between health communication stakeholders and communities is crucial for effectively disseminating structured information and culturally appropriate messages, ultimately contributing to raising awareness of HBV.

The challenges of integrating an immigrant population with chronic hepatitis B into long-term hepatology care: Lessons learned from a Bronx West African screening program. IJID REGIONS 2024; 12:100385. [PMID: 39070138 PMCID: PMC11278613 DOI: 10.1016/j.ijregi.2024.100385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 06/04/2024] [Accepted: 06/05/2024] [Indexed: 07/30/2024]
Abstract
Objectives Hepatitis B virus (HBV) is endemic in West Africa. Because of immigration to the United States, screening and transition to long-term care is a significant public health concern. We describe the challenges of integrating individuals identified in a screening program into long-term care and the spectrum of disease severity. Methods Between 2019 and 2023, 749 individuals were screened. Beginning 2022, all were offered a free serologic evaluation. Details of the previous diagnosis, HBV care, the serologic evaluation, aspartate aminotransferase to platelet ratio index, and Fibrosis index-4 scores were recorded. The results of transient elastography (TE) were correlated with the serologic evaluation. Results A total of 75 (10%) individuals were hepatitis B surface antigen-positive, including 58 (77.3%) previously and 17 (22.7%) newly diagnosed. Despite attempts at linkage to care, only 14 (37.8%) of those diagnosed before the offer continued and/or entered long-term care. A total of 63 of 75 (84%) returned for the evaluation. Among 56 HBV treatment-naïve individuals, 66.1% had a serologic profile consistent with the carrier state. A total of 10 (18.2%) individuals met the criteria for HBV therapy, and 10 (21.7%) had ≥F2 fibrosis on TE. There was no correlation between aspartate aminotransferase to platelet ratio index and Fibrosis index-4 scores and TE. Eight (29.6%) of 27 patients with a profile of the HBV carrier state had ≥F2 fibrosis. Conclusion Integration of individuals with HBV from West Africa identified in a screening program into long-term care is challenging. Inclusion of a serologic evaluation in programs for immigrant communities should be considered. Up to 30% of individuals with a serologic profile consistent with the HBV carrier state may have ≥F2 fibrosis.

Abstract
This paper investigates linkage to care following community-based screening for hepatitis B virus (HBV) in rural Senegal. HBV-positive participants who completed a biological and clinical examination to assess liver disease and treatment eligibility were referred to a regional hospital (if eligible for treatment), invited to join the Sen-B research cohort study (adults with detectable viral load) or referred to their local health centre (all others). Logistic regressions were conducted to investigate factors associated with (i) uptake of the scheduled post-screening examination, and (ii) HBV management initiation. Obstacles to HBV management were identified using thematic analysis of in-depth patient interviews. Of the 206 HBV-positive participants, 163 (79.1%) underwent the examination; 47 of the 163 (28.8%) initiated HBV management. Women, people not migrating for >6 months/year, individuals living in households with more agricultural and monetary resources, with other HBV-positive participants, and beneficiaries of the national cash transfer program, were all more likely to undergo the examination. The likelihood of joining the Sen-B cohort increased with household monetary resources, but decreased with agricultural resources. Initiation of HBV management in local health centre was higher among participants with a non-agricultural economic activity. Individuals reported wariness and confusion about HBV management content and rationale at various stages of the care continuum, in particular with respect to venous blood sampling and management without treatment. In conclusion, HBV community-based test-and-treat strategies are feasible, but early loss to follow-up must be addressed through simplified, affordable management and community support and sensitization.

Abstract
Background Hepatitis B (HBV) and hypertension (HTN) are prevalent in West Africa (WA). Inadequate control is common, and evaluation and management are challenging among immigrants due to unfamiliarity with the United States (US) healthcare system. While HBV is stigmatised, HTN is recognised as an important condition. We describe how a HTN screening program can facilitate HBV screening in the Bronx WA community. Methods Thirty-minute HTN educational programs were delivered in collaboration with faith-based organisations, and 5-min presentations were presented upon request at community gatherings. Arrangements were made for those interested in a clinic visit where a questionnaire was completed, blood pressure (BP) measured, a free BP cuff provided, HBV testing performed, and referrals made. For those without ongoing care, insurance was arranged, and linkage to care provided. Findings Seven 30-min and five 5-min presentations were conducted. After the 30-min presentation, 204 of 445 attendees (45.8%) requested a visit, and 68 (33.3%) attended the visit. After the 5-min presentation, 80 requested a visit and 51 (63.8%) attended the visit. A BP >140/90 mmHg was present in 122 individuals (48.4%), including 43 (17.1%) without a history of HTN and 39 (15.5%) with BP >160/90 mmHg. All except two who reported previous testing agreed to HBV testing. 19 (7.5%) were hepatitis B surface antigen positive. Transition into ongoing care was provided for 60 (33.9%) with HTN who were not integrated into the US healthcare system. Interpretation HTN screening with a free BP cuff promotes HBV screening and US healthcare integration. Funding No funding.

Abstract
In Vietnam and the Philippines, viral hepatitis is the leading cause of cirrhosis and liver cancer. This study aims to understand the barriers and enablers of people receiving care for hepatitis B and C to support both countries' efforts to eliminate viral hepatitis as a public health threat by 2030. Retrospective, semi-structured interviews were conducted with a purposive, quota-based sample of 63 people living with hepatitis B or C in one province of Vietnam and one region of the Philippines. A rapid deductive approach to thematic analysis produced key findings among the three phases of care: (1) pre-awareness and testing, (2) linkage and treatment initiation and (3) ongoing treatment and recovery. The research found that participants followed five typical journeys, from a variety of entry points. Barriers during the pre-awareness and testing phase included limited awareness about hepatitis and its management, stigma and psychological impacts. Enablers included being familiar with the health system and/or patients benefiting from social connections within the health systems. During the linkage and treatment initiation phase, barriers included difficult physical access, complex navigation and inadequate counselling. In this phase, family support emerged as a critical enabler. During the ongoing treatment and recovery phase, the cost of care and socially and culturally informed perceptions of the disease and medication use were both barriers and enablers. Exploring peoples' journeys with hepatitis B and C in Vietnam and the Philippines revealed many similarities despite the different cultural and health system contexts. Insights from this study may help generate a contextualized, people-centred evidence base to inform the design and improvement of primary care services for hepatitis in both research sites.

Abstract
BACKGROUND Chronic liver disease is a major cause of premature death in sub-Saharan Africa. Efficacy of antiviral therapy among patients with hepatitis B virus (HBV)-related cirrhosis is not well established in Africa. We described the clinical characteristics and outcomes of patients with cirrhosis and hepatocellular carcinoma in The Gambia and assessed the impact of tenofovir disoproxil fumarate (TDF) on survival of HBV-infected patients with cirrhosis. METHODS In this prospective cohort study, we followed up adults who were consecutively diagnosed with cirrhosis or hepatocellular carcinoma between 2012 and 2015 in The Gambia, west Africa. Patients with chronic HBV infection and cirrhosis, without hepatocellular carcinoma, were offered TDF. Primary outcome was overall survival. To determine the effect of TDF on survival, we performed a Cox proportional hazard regression model with inverse probability of treatment weighting (IPTW) based on propensity score. FINDINGS Of 529 patients enrolled in this study, 336 patients (252 with hepatocellular carcinoma and 84 with cirrhosis) were analysed. Patients were predominantly male (253 [75%] men and 83 [25%] women), with a median age of 42 years (IQR 33-55). 276 (84%) of 327 of patients with data were positive for HBV biomarkers, 31 (10%) of 311 were positive for hepatitis C virus antibodies, and 22 (10%) of 223 were positive for hepatitis D virus antibodies. 64% of patients with hepatocellular carcinoma had multifocal tumour, with a median size of 7·5 cm (IQR 5·4-10·8). 173 patients with hepatocellular carcinoma and 70 patients with cirrhosis were included in the survival analysis. Median survival was 1·5 months (95% CI 1·1-2·0) in patients with hepatocellular carcinoma and 17·1 months (11·2-24·0) in patients with cirrhosis (log-rank p<0·0001). In patients with hepatocellular carcinoma, ascites (hazard ratio [HR] 1·78, 95% CI 1·21-2·60), partial or complete portal thrombosis (HR 2·61, 1·58-4·30), and platelet count (HR 1·80, 1·19-2·70) were independent predictive factors of mortality at baseline. In HBV-infected patients with cirrhosis, median turnaround time between cirrhosis diagnosis and TDF initiation was 4·9 months (IQR 3·2-7·3). In IPTW analysis, TDF treatment was associated with improved survival in patients with HBV-related cirrhosis (adjusted HR 0·14, 0·06-0·34; p<0·0001). INTERPRETATION These results highlight poor survival of patients with cirrhosis or hepatocellular carcinoma as well as the effectiveness of TDF in reducing the premature mortality of patients with cirrhosis and HBV infection. Interventions for early diagnosis and treatment of cirrhosis as well as screening programmes for hepatocellular carcinoma are urgently required in Africa.

Enjeux et difficultés de l'accès aux traitements pour la prise en charge de l'hépatite B chronique à Madagascar : étude qualitative auprès des soignants et personnes atteintes. Rev Epidemiol Sante Publique 2023; 71:102088. [PMID: 37352795 DOI: 10.1016/j.respe.2023.102088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 03/24/2023] [Accepted: 05/15/2023] [Indexed: 06/25/2023] Open
Abstract
OBJECTIVES Madagascar faces many difficulties in accessing diagnosis and treatment of hepatitis B. The prevalence of chronic hepatitis B infection is estimated at 6.9%. The costs associated with screening and treatment are high and not easily accessible. This article proposes a reflection on the challenges and difficulties of access to diagnosis and treatment for patients with chronic hepatitis B. METHOD The "Neo Vac" study aimed to document the life paths of people living with chronic hepatitis B, their difficulties and their perceptions of HBV. Twenty-three semi-structured interviews were conducted in 2019 in Antananarivo with patients and gastroenterologists. RESULTS The study describes the numerous obstacles that mark the therapeutic pathways of chronic HBV patients. The first result indicates lack of knowledge of the disease by chronic HBV patients and the varied circumstances in which the disease is discovered. None of the persons interviewed had been screened on their own initiative, the screening having taken place during prenatal consultations or emergency hospitalizations or during a morbidity episode. The care pathway was characterized by doubt and anxiety due to lack of knowledge about the possible disease outcome and concern about the costs of care. DISCUSSION Little known by the population and health professionals, hepatitis B is rarely the subject of voluntary screening and is most often detected during an apparently unrelated health event. The exorbitant cost of treatment for patients, the cost of medical analyses and secondary costs, and the unavailability of follow-up tests outside the capital constitute barriers to access to care that are insurmountable for the majority of the Malagasy population. CONCLUSIONS This first qualitative study on the experiences of HBV-infected persons in terms of access to care and treatment in Madagascar underlines the extent to which access to treatment remains limited, due to the absence of a national policy for the prevention, screening and management of hepatitis B, which remains a highly neglected and unrecognized disease in Madagascar as well as internationally.

Abstract
Nigeria is estimated to have the largest number of children worldwide, living with chronic hepatitis B virus (HBV) infection, the leading cause of liver cancer. Up to 90% of children infected at birth develop chronic HBV infection. A birth dose of the hepatitis B vaccine (HepB-BD) followed by at least two additional vaccine doses is recommended for prevention. This study assessed barriers and facilitators of HepB-BD administration and uptake, using structured interviews with healthcare providers and pregnant women in Adamawa and Enugu States, Nigeria. The Consolidated Framework for Implementation Sciences Research (CFIR) guided data collection and analysis. We interviewed 87 key informants (40 healthcare providers and 47 pregnant women) and created a codebook for data analysis. Codes were developed by reviewing the literature and reading a subsample of queries line-by-line. The overarching themes identified as barriers among healthcare providers were: the lack of hepatitis B knowledge, limited availability of HepB-BD to vaccination days only, misconceptions about HepB-BD vaccination, challenges in health facility staffing capacity, costs associated with vaccine transportation, and concerns related to vaccine wastage. Facilitators of timely HepB-BD vaccination included: vaccine availability, storage, and hospital births occurring during immunization days. Overarching themes identified as barriers among pregnant women were lack of hepatitis B knowledge, limited understanding of HepB-BD importance, and limited access to vaccines for births occurring outside of a health facility. Facilitators were high vaccine acceptance and willingness for their infants to receive HepB-BD if recommended by providers. Findings indicate the need for enhanced HepB-BD vaccination training for HCWs, educating pregnant women on HBV and the importance of timely HepB-BD, updating policies to enable HepB-BD administration within 24 hours of birth, expanding HepB-BD availability in public and private hospital maternity wards for all facility births, and outreach activities to reach home births.

Abstract
INTRODUCTION Despite the early implementation of hepatitis B vaccination and the ongoing decentralisation of chronic hepatitis B (CHB) care, over 10% of the Senegalese adult population lives with CHB and liver cancer remains a main cause of death. Investigating factors associated with CHB infection, prevention of CHB-related morbidity, and prevention and treatment of mortality secondary to CHB calls for a holistic and multidimensional approach. This paper presents the adaptation of the health capability profile (HCP) to a specific epidemiological issue and empirical setting: it seeks to identify and analyse inter-related abilities and conditions (health capabilities) in relation to the CHB epidemic in the rural area of Niakhar, Senegal. METHODS AND ANALYSIS This ongoing study relies on a sequential social justice mixed-methods design. The HCP is comprehensively adapted to CHB in rural Senegal and guides the design and conduct of the study. Objective and subjective data are collected at the individual level following a mixed-methods explanatory core design. The quantitative module, embedded in the ANRS12356 AmBASS cross-sectional survey (exhaustive sampling), is used to select a purposeful sampling of participants invited for one-on-one qualitative interviews. Additional data are collected at the institutional and community level through health facility surveys and an ethnography (in-depth interviews) of local and national CHB stakeholders. Data analysis adopts a synergistic approach to produce a multilayered analysis of individual HCPs and crosscutting analysis of the 15 health capabilities. The data integration strategy relies on a mixed-methods convergent core design, and will use 0-100 health capability scores as well as flow diagrams to measure and characterise levels of development and interactions among health capabilities, respectively. ETHICS AND DISSEMINATION This study was approved by Senegalese and French authorities. Results dissemination through local workshops and scientific publications aim at fuelling effective policy change towards CHB-related health capability.

Abstract
Background Many residents of the Bronx are from West Africa where chronic hepatitis B is endemic. Hepatitis B screening is low in West African immigrant communities due to multiple possible cultural and socioeconomic factors. Methods A culturally sensitive educational program on hepatitis B with a special emphasis on the relevance for the West African community was developed. Arrangements were made with leaders of West African faith-based organizations to conduct educational programs following religious services after which a survey was completed to assess changes in attitudes towards the infection and motivation for testing. Arrangements were then made for serologic testing at which time hypertension screening was also performed. Findings Nine events in which a total of 550 people attended were held. Among the 339 (61.6%) participants who completed the questionnaire, 325 of the participants (95.1%) reported improved understanding, and 236 (67.0%) indicated greater comfort in sharing a meal and talking with an infected individual. Two hundred seventy-four participants (82.7%) indicated an intention to undergo testing, and 339 (97.8%) indicated that they would encourage family and friends to undergo screening. Three hundred thirty-two of the 550 participants (60.3%) requested serologic testing. Among those requesting testing, 224 (67.5%) underwent testing. Interpretation A culturally sensitive educational program in collaboration with faith-based organizations is effective in motivating people from West Africa to undergo screening for hepatitis B at which time other preventative health care measures such as hypertension screening can be performed.

Abstract
Elimination of viral hepatitis in sub-Saharan Africa by 2030 is an ambitious feat. However, as stated by the World Health Organization, there are unprecedented opportunities to act and make significant contributions to the elimination target. With 60 million people chronically infected with hepatitis B virus (HBV) of whom 38800 are at risk of developing highly fatal hepatocellular carcinoma (HCC) every year, sub-Saharan Africa faces one of the greatest battles towards elimination of viral hepatitis. There is a need to examine progress in controlling the disproportionate burden of HBV-associated HCC in sub-Saharan Africa within the context of this elimination target. By scaling-up coverage of hepatitis B birth dose and early childhood vaccination, we can significantly reduce new cases of HCC by as much as 50% within the next three to five decades. Given the substantial reservoir of chronic HBV carriers however, projections show that HCC incidence and mortality rates in sub-Saharan Africa will double by 2040. This warrants urgent public health attention. The trends in the burden of HCC over the next two decades, will be determined to a large extent by progress in achieving early diagnosis and appropriate linkage to care for high-risk chronic HBV infected persons.

Impact of Introducing Hepatitis B Birth Dose Vaccines into the Infant Immunization Program in Burkina Faso: Study Protocol for a Stepped Wedge Cluster Randomized Trial (NéoVac Study).

Abstract
To achieve global hepatitis elimination by 2030, it is critical to prevent the mother-to-child transmission (MTCT) of hepatitis B virus (HBV). Since 2009, the WHO has recommended administering hepatitis B vaccine to all neonates within 24 h of birth to prevent MTCT. However, many countries in sub-Saharan Africa only provide hepatitis B immunization at the age of 6, 10, and 14 weeks or 8, 12, and 16 weeks using a combined vaccine. To accelerate the introduction of the hepatitis B birth dose vaccine (HepB-BD) into sub-Saharan Africa, it is critical to establish to what extent the addition of HepB-BD can further reduce HBV transmission in areas where three-dose infant vaccination has been implemented. We therefore designed a study to evaluate the impact, acceptability, and cost-effectiveness of incorporating the HepB-BD into the routine immunization program in a real-life field condition in Burkina Faso, where the hepatitis B vaccination is currently scheduled at 8-12-16 weeks. Through a multidisciplinary approach combining epidemiology, anthropology, and health economics, the Neonatal Vaccination against Hepatitis B in Africa (NéoVac) study conducts a pragmatic stepped wedge cluster randomized controlled trial in rural areas of the Hauts-Bassins Region. The study was registered in ClinicalTrials.gov (identifier: NCT04029454). A health center is designated as a cluster, and the introduction of HepB-BD will be rolled out sequentially in 24 centers. Following an initial period in which no health center administers HepB-BD, one center will be randomly allocated to incorporate HepB-BD. Then, at a regular interval, another center will be randomized to cross from the control to the intervention period, until all 24 centers integrate HepB-BD. Pregnant women attending antenatal care will be systematically invited to participate. Infants born during the control period will follow the conventional immunization schedule (8-12-16 weeks), while those born in the interventional period will receive HepB-BD in addition to the routine vaccines (0-8-12-16 weeks). The primary outcome, the proportion of hepatitis B surface antigen (HBsAg) positivity in infants aged at 9 months, will be compared between children born before and after HepB-BD introduction. The study will generate data that may assist governments and stakeholders in sub-Saharan Africa to make evidence-based decisions about whether to add HepB-BD into the national immunization programs.

Abstract
Only a fraction of the estimated tenth or so of Senegalese who are chronically infected with hepatitis B virus (HBV) have been diagnosed. Of these, few have been assessed for their risk of progressing to potentially fatal liver disease (indicating need for treatment), and fewer still are taking antiviral drugs. A massive gap between those needing and getting treatment is widely acknowledged among experts. But given that HBV and its biomedical treatment options are largely invisible in bodies, health data, care practices, public messaging, or mass media, how can we observe, ethnographically, the effects of constraints on and inequalities in treatment? What are the stakes of access to drugs, when this access is not being sought out, claimed, or enacted? This article tackles these questions by examining how HBV is being enacted in Senegal, but not necessarily in relation to antiviral treatment. I first describe the emergence, over the past decade and a half, of an exclusionary topography of HBV diagnosis and treatment. I introduce the notion of “filtration” to describe the effects of this topography on the formation of potential “subjects of access.” The diagnostic therapies and expertise required to determine need for treatment are expensive, urban, and largely privatized. Moreover, knowledge about HBV and its possibilities of care circulates in narrow and sparsely distributed channels. Only a tiny minority of persons are effectively “filtered into” care, while issues of access remain largely outside of public debate. I then move onto small-scale efforts, led by rural primary health workers and community associations, to raise awareness of and expand screening for HBV. Those driving information and screening either do not reveal that effective drugs exist or locate these beyond the reach of most of their audiences or patients. Why then do they do it? I examine the logics and effects of their work to identify the forms of inclusion, care, efficacy, and explanation these open up. At the same time, I seek to discern the indirect effects of unequal access to knowledge and resources in the ambivalence, uncertainties, and contradictions that pervade these efforts to inform, diagnose, and advise.
