Abstract
INTRODUCTION The introduction of direct-acting antivirals (DAAs) has significantly transformed the therapeutic landscape for chronic C hepatitis virus (HCV) infection. However, there is still room for further improvement in optimizing therapy efficacy and minimizing adverse effects. AREAS COVERED This review is devoted to the rationale for adopting a personalized approach to HCV therapy. Specifically, we explore the role of host-related factors, such as sex or the presence of comorbidities. We thoroughly examine the implications of commonly encountered comorbidities, including HIV infection, chronic renal disease, liver cirrhosis, and other chronic viral hepatitis infections. Additionally, we discuss the prevalent drug-to-drug interactions between DAAs and other medications, while providing guidance on their management. Finally, we investigate viral-related issues that can influence treatment outcomes, such as viral genotype, quasi-species, and the presence of resistance-associated mutations. EXPERT OPINION Despite pivotal trials demonstrating efficacy rates exceeding 90% for currently available DAA regimens, there are still opportunities to optimize therapy outcomes and tailor treatment to each patient. This can be achieved through a meticulous evaluation of the patient's specific clinical conditions and comorbidities, a vigilant approach to manage potential drug interactions, and diligent patient follow-up.

Møgelmose S, Neels K, Hens N. Incorporating human dynamic populations in models of infectious disease transmission: a systematic review. BMC Infect Dis 2022; 22:862. [DOI: 10.1186/s12879-022-07842-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Accepted: 11/04/2022] [Indexed: 11/19/2022] Open
Abstract
Abstract
Background
An increasing number of infectious disease models consider demographic change in the host population, but the demographic methods and assumptions vary considerably. We carry out a systematic review of the methods and assumptions used to incorporate dynamic populations in infectious disease models.
Methods
We systematically searched PubMed and Web of Science for articles on infectious disease transmission in dynamic host populations. We screened the articles and extracted data in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
Results
We identified 46 articles containing 53 infectious disease models with dynamic populations. Population dynamics were modelled explicitly in 71% of the disease transmission models using cohort-component-based models (CCBMs) or individual-based models (IBMs), while 29% used population prospects as an external input. Fertility and mortality were in most cases age- or age-sex-specific, but several models used crude fertility rates (40%). Households were incorporated in 15% of the models, which were IBMs except for one model using external population prospects. Finally, 17% of the infectious disease models included demographic sensitivity analyses.
Conclusions
We find that most studies model fertility, mortality and migration explicitly. Moreover, population-level modelling was more common than IBMs. Demographic characteristics beyond age and sex are cumbersome to implement in population-level models and were for that reason only incorporated in IBMs. Several IBMs included households and networks, but the granularity of the underlying demographic processes was often similar to that of CCBMs. We describe the implications of the most common assumptions and discuss possible extensions.

What China can learn from Malaysia to achieve the goal of "eliminate hepatitis C as a public health threat" by 2030 - a narrative review. LANCET REGIONAL HEALTH-WESTERN PACIFIC 2021; 16:100261. [PMID: 34590064 PMCID: PMC8429955 DOI: 10.1016/j.lanwpc.2021.100261] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Revised: 08/03/2021] [Accepted: 08/04/2021] [Indexed: 02/04/2023]
Abstract
Background: To discuss a range of strategic options for China to improve the accessibility of direct antiviral agents (DAAs) as the treatment for hepatitis C. Methods: We adopted a narrative review approach for comprehensive comparisons and in-depth analyses of the country context, and barriers of increasing the DAA treatment rate of hepatitis C in Malaysia and China, and how the two countries have been navigating the hepatitis C agenda. Findings: Malaysia adopted a series of successful strategies to scale up the diagnosis of hepatitis C and DAA treatment, which have valuable implications for China. Interpretation: The potential game-changing strategies for China to adapt from Malaysian experiences range from the stepping-up of political commitment and leadership, enhanced market competition, simplified and decentralized treatment at the strengthened primary care level, integrated healthcare services, coordinated government initiatives, to multi-organizational participation and civil society's active role in raising public awareness, and training of non-specialist physicians. Embarking on scale-up of hepatitis C treatment marks another contribution of China to improve the health of not only the Chinese citizens but also mankind, which is an important component for building healthy Chinese and global communities. Funding: No funding supported this study.

Merat S. SD1000: High Sustained Viral Response Rate in 1361 Patients With Hepatitis C Genotypes 1, 2, 3, and 4 Using a Low-cost, Fixed-dose Combination Tablet of Generic Sofosbuvir and Daclatasvir: A Multicenter, Phase III Clinical Trial. Clin Infect Dis 2021; 70:2206-2212. [PMID: 31504303 DOI: 10.1093/cid/ciz628] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Accepted: 07/09/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The combination of sofosbuvir and daclatasvir is a potent, pangenotypic regimen suitable for mass-scale hepatitis C treatment, especially in resource-limited countries where newer, expensive combinations are not available. This combination has been widely tested on genotype 4. However, Phase III trials of this combination in other genotypes have been cost prohibitive. With the introduction of generic, low-cost sofosbuvir and daclatasvir, large-scale studies in resource-limited countries are now possible. METHODS Sofosbuvir at 400 mg and daclatasvir at 60 mg were coformulated into a fixed-dose combination (FDC) tablet (Sovodak, Rojan Pharma, Tehran, Iran). Patients from 46 centers were dosed for 12 or 24 weeks with or without ribavirin, in line with existing guidelines. Responses to treatment were evaluated 12 weeks after the end of treatment (for a sustained virological response at Week 12; SVR12). RESULTS There were 1361 patients recruited. Overall, the patients were 21% female, with a mean age of 50 years; 39% were cirrhotic; 22% were treatment-experienced; 47% were genotype 1, 41% were genotype 3, and 2% were other genotypes. The genotype was not known in 10% of the patients. The intention-to-treat and per-protocol SVR12 rates were 94.7% and 98.8%, respectively. The safety profile was unremarkable, treatment was well tolerated, and compliance with the single-tablet regimen was excellent. CONCLUSIONS The treatment with FDC of sofosbuvir and daclatasvir achieved high SVR12 rates, equivalent to those seen in Phase III trials of other pangenotypic options, and has been conducted at a similar scale in a representative, real-world population at a cost of under $100 per patient, which makes this combination suitable for elimination protocols in resource-limited countries.

Long-term clinical benefits of Sofosbuvir-based direct antiviral regimens for patients with chronic hepatitis C in Central and West Africa. Liver Int 2020; 40:2643-2654. [PMID: 32687669 DOI: 10.1111/liv.14613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 07/09/2020] [Accepted: 07/13/2020] [Indexed: 02/13/2023]
Abstract
BACKGROUND In Sub-Saharan Africa, chronic hepatitis C (CHC) is a major public health issue. We estimated the long-term clinical benefits of treating CHC with sofosbuvir-based regimens in Cameroon, Côte d'Ivoire and Senegal using Markov model combining data from the literature with estimates of direct-acting antiviral (DAAs) effectiveness in West and Central Africa. METHODS Disease progression was simulated with and without treatment in fictive cohorts of patients "diagnosed" with CHC in Cameroon (n = 3224), Côte d'Ivoire (n = 9748) and Senegal (n = 6358). Lifetime treatment benefits were assessed using (a) life-years saved (LYS); (b) life-years (LY) avoided in compensated cirrhosis (CC), decompensated cirrhosis (DC) and hepatocellular carcinoma; and (c) comparison of the proportions of patients at each disease stage with and without treatment. Probabilistic and determinist sensitivity analyses were performed to address uncertainty. RESULTS Sofosbuvir-based treatment would save [mean, 95% confidence intervals] 3.3 (2.5; 5.7) LY per patient in Cameroon, 2.7 (2.1; 4.8) in Côte d'Ivoire and 3.6 (2.8; 6.3) in Senegal. With treatment, approximately 6% (1%) of the patients still alive in each of the study countries would be in the CC (DC) health state 11 (15) years after CHC diagnosis, vs 15% (5%) without treatment. Scenario analysis showed earlier diagnosis and treatment initiation would dramatically improve LYS and morbidity. CONCLUSION Sofosbuvir-based treatment could significantly reduce CHC-related mortality and help control CHC-related liver disease progression in West and Central Africa. However, the goal of disease elimination necessitates a substantial decrease in DAAs prices, greater political commitment and increases in both national and external health expenditures.

Abstract
Background: Access to healthcare services is a basic human right. Objective: The main purpose of this study is to assess the association between accessibility of needle and syringe programs (NSP) and injecting and sharing risk behaviors. Methods: A cross-sectional study employed respondent-driving sampling (RDS) to recruit a sample of 634 people who inject drugs (PWID) from three provinces, Golestan, Ardabil, and Sistan and Baluchestan, in Iran between November 2018 and February 2019. Participants completed a questionnaire based on the WHO Drug Injecting Study Phase II survey. Results: Participants reported their accessibility of NSP services as low (6%), middle (19%), and high (75%) in the past 2 months at the time of the survey. PWID who had increased access to NSP services were less likely to report utilization of used cooker (aOR = 1.40; CI 95% 0.99-1.82), cotton (aOR = 1.30; CI 95% 0.79-1.81), and water (aOR = 1.07; CI 95% 0.89-1.26), receptive needle/syringe sharing (aOR= 1.86, 95% CI 1.69-2.03), and distributive needle/syringe sharing (aOR= 1.09, 95% CI 0.81-1.37). Conclusions/Importance: There is evidence of inequality in PWID's access to health care as they relate to the prevention of HCV transmission. An understanding of both the social determinants and prevention of injecting and sharing risk behaviors seeks to connect HCV risk reduction within the context of human rights and vulnerability.

Abstract
BACKGROUND Population-level monitoring of hepatitis C virus (HCV) infected people across cascades of care identifies gaps in access and engagement in care and treatment. We characterized the population-level care cascade for HCV in British Columbia (BC), Canada before and after introduction of Direct Acting Antiviral (DAA) treatment. METHODS BC Hepatitis Testers Cohort (BC-HTC) includes 1.7 million individuals tested for HCV, HIV, reported cases of hepatitis B, and active tuberculosis in BC from 1990 to 2018 linked to medical visits, hospitalizations, cancers, prescription drugs and mortality data. We defined six HCV care cascade stages: (a) antibody diagnosed; (b) RNA tested; (c) RNA positive; (d) genotyped; (e) initiated treatment; and (f) achieved sustained virologic response (SVR). RESULTS We estimated 61 127 people were HCV antibody positive in BC in 2018 (undiagnosed: 7686, 13%; diagnosed: 53 441, 87%). Of those diagnosed, 83% (44 507) had HCV RNA testing, and of those RNA positive, 90% (28 716) were genotyped. Of those genotyped, 61% (17 441) received therapy, with 90% (15 672) reaching SVR. Individuals from older birth cohorts had lower progression to HCV RNA testing. While people who currently inject drugs had the highest proportional progression to RNA testing, this group had the lowest proportional treatment uptake. CONCLUSIONS Although gaps in HCV RNA and genotype testing after antibody diagnosis exist, the largest gap in the care cascade is treatment initiation, despite introduction of DAA treatment and removal of treatment eligibility restrictions. Further interventions are required to ensure testing and treatment is equitably accessible in BC.

Taye BW. A Path to Ending Hepatitis C in Ethiopia: A Phased Public Health Approach to Achieve Micro-Elimination. Am J Trop Med Hyg 2019; 101:963-972.

Abstract
Ethiopia's hepatitis C virus (HCV) prevalence is predicted to rise by 2030. To halt this increasing trend, a suitable approach to the elimination of HCV is needed. This review explores the current status, challenges, and opportunities and outlines a strategy for the micro-elimination approach in Ethiopia. I searched PubMed and EMBASE using combined Medical Subject Heading databases for the literature on HCV micro-elimination. A phased public health approach to HCV micro-elimination, including preparation/capacity building (phase I), implementation (phase II), and rollout and scale-up (phase III), targeting people living with HIV, prisoners, chronic hepatitis and cancer patients, blood donors, and pregnant women is a pragmatic strategy to Ethiopia. This can be implemented at general and tertiary care referral hospitals with a future scale-up to district hospitals through task-shifting by training general practitioners, nurses, laboratory technologists, and pharmacists. Availability of the highly effective direct-acting antivirals (DAAs) can be ensured by expanding the existing program that provides highly subsidized DAAs through an agreement with Gilead Sciences, Inc. and eventually aiming at domestic generic manufacturing. The significant enablers to HCV micro-elimination in Ethiopia include the control of healthcare-associated HCV infection, blood safety, access to affordable testing and pan-genotypic DAAs, task-shifting, multisectoral partnership, and regulatory support. General population-based HCV screening and treatment are not cost-effective for Ethiopia because of high cost, program complexity, and disease epidemiology.

Abstract
BACKGROUND AND AIM The prohibitively high cost of direct-acting antivirals (DAA) for hepatitis C virus (HCV) infection remains a barrier to treatment access in Singapore. We aimed to evaluate whether DAA as first-line therapy would be cost-effective for genotype 3 (GT3) HCV patients compared with pegylated interferon and ribavirin (PR). METHODS A decision tree analysis was used to compare the costs and outcomes of DAA and PR as first-line therapy. Treatment effectiveness, defined as sustained virological response, was assessed using a retrospective cohort of treated GT3 HCV patients. Direct medical costs were estimated from the payer's perspective using billing information. We obtained health utilities from published literature. We performed extensive one-way sensitivity analyses and probabilistic sensitivity analyses to account for uncertainties regarding the model parameters. RESULTS In base case analysis, first-line therapy with DAA and PR yielded quality-adjusted life years (QALYs) of 0.69 and 0.62 at a cost of USD 54 634 and USD 23 857, respectively. The resultant incremental cost-effectiveness ratio (ICER) (USD 449 232/QALY) exceeded the willingness-to-pay threshold (USD 53 302/QALY). The ICER was robust for uncertainties regarding the model parameters. The cost of DAA is the key factor influencing the cost-effectiveness of HCV treatment. At current price, DAA as first-line therapy is not cost-effective compared with PR, with or without consideration of retreatment. Threshold analysis suggested that DAA can be cost-effective if it costs less than USD 17 002 for a 12-week treatment course. CONCLUSION At current price, DAA as first-line therapy is not cost-effective compared with PR in GT3 HCV patients in Singapore.

Abstract
BACKGROUND The revolution in hepatitis C virus (HCV) treatment through the development of direct-acting antivirals (DAAs) has generated international interest in the global elimination of the disease as a public health threat. In 2017, this led WHO to establish elimination targets for 2030. We evaluated the impact of public health interventions on the global HCV epidemic and investigated whether WHO's elimination targets could be met. METHODS We developed a dynamic transmission model of the global HCV epidemic, calibrated to 190 countries, which incorporates data on demography, people who inject drugs (PWID), current coverage of treatment and prevention programmes, natural history of the disease, HCV prevalence, and HCV-attributable mortality. We estimated the worldwide impact of scaling up interventions that reduce risk of transmission, improve access to treatment, and increase screening for HCV infection by considering six scenarios: no change made to existing levels of diagnosis or treatment; sequentially adding the following interventions: blood safety and infection control, PWID harm reduction, offering of DAAs at diagnosis, and outreach screening to increase the number diagnosed; and a scenario in which DAAs are not introduced (ie, treatment is only with pegylated interferon and oral ribavirin) to investigate the effect of DAA use. We explored the effect of varying the coverage or impact of these interventions in sensitivity analyses and also assessed the impact on the global epidemic of removing certain key countries from the package of interventions. FINDINGS By 2030, interventions that reduce risk of transmission in the non-PWID population by 80% and increase coverage of harm reduction services to 40% of PWID could avert 14·1 million (95% credible interval 13·0-15·2) new infections. Offering DAAs at time of diagnosis in all countries could prevent 640 000 deaths (620 000-670 000) from cirrhosis and liver cancer. A comprehensive package of prevention, screening, and treatment interventions could avert 15·1 million (13·8-16·1) new infections and 1·5 million (1·4-1·6) cirrhosis and liver cancer deaths, corresponding to an 81% (78-82) reduction in incidence and a 61% (60-62) reduction in mortality compared with 2015 baseline. This reaches the WHO HCV incidence reduction target of 80% but is just short of the mortality reduction target of 65%, which could be reached by 2032. Reducing global burden depends upon success of prevention interventions, implemention of outreach screening, and progress made in key high-burden countries including China, India, and Pakistan. INTERPRETATION Further improvements in blood safety and infection control, expansion or creation of PWID harm reduction services, and extensive screening for HCV with concomitant treatment for all are necessary to reduce the burden of HCV. These findings should inform the ongoing global action to eliminate the HCV epidemic. FUNDING Wellcome Trust.

Abstract
Hepatitis C virus contributes to substantial and growing mortality and morbidity. Fortunately, the advent of highly effective interferon-free direct-acting antiviral (DAA) medications and new diagnostic tests has the potential to dramatically alter the epidemiologic trajectory of hepatitis C, particularly for "hard-to-reach" populations. Treatment advances and cure will also likely alter the individual experience of living with hepatitis C. However, it is not yet known in what capacity. This paper provides an overview of the population-level impact of DAA treatment, highlighting the need to further our understanding of the impact of treatment on behaviour, health and wellbeing through lived experience and more sensitive patient-reported outcome measures.

Hepatitis C virus surveillance and identification of human pegivirus 2 in a large Cameroonian cohort. J Viral Hepat 2019; 26:30-37. [PMID: 30187640 PMCID: PMC7379692 DOI: 10.1111/jvh.12996] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Revised: 07/20/2018] [Accepted: 08/14/2018] [Indexed: 12/11/2022]
Abstract
The prevalence of chronic hepatitis C virus (HCV) and the presence of human pegivirus 2 (HPgV-2) have not been examined in Cameroon, although HCV has been associated with HPgV-2 infections previously. Herein we aimed to characterize the burden and genetic diversity of HCV and the presence of HPgV-2 in Cameroon. Retrospective plasma specimens collected from N = 12 369 consenting subjects in South Cameroon from 2013 to 2016 were included in the study. The majority (97.1%) of participants were patients seeking health care. All specimens were screened for HCV using the Abbott RealTime HCV viral load assay and positive specimens with remaining volume were also screened for HPgV-2 antibodies on the Abbott ARCHITECT instrument, followed by molecular characterization. Overall, HCV RNA was detected in 305 (2.47%; 95% CI: 2.21%-2.75%) specimens. Notably, the prevalence of HCV RNA was 9.09% amongst participants over age 40 and 3.81% amongst males. Phylogenetic classification of N = 103 HCV sequences identified genotypes 1 (19.4%), 2 (15.5%) and 4 (65.1%) within the study cohort. Amongst HCV RNA-positive specimens, N = 28 (10.6%; 95% CI: 7.44%-14.90%) specimens also had detectable HPgV-2 antibodies. Of these, N = 2 viremic HPgV-2 infections were confirmed by sequencing and shared 93-94 median % identity with strains found on other continents. This is the first study to determine the prevalence of chronic HCV in Cameroon, and the discovery of HPgV-2 in this study cohort expands the geography of HPgV-2 to the African continent, indicating a widespread distribution exists.

Abstract
BACKGROUND To study the epidemiology of chronic hepatitis C virus infection in Hong Kong and to estimate the service gap for achieving the WHO hepatitis elimination targets of attaining a diagnosis rate of 90%, treatment rate of 80% and 65% reduction in mortality rate by 2030. METHODS From January 2005 to March 2017, patients who were tested positive for anti-HCV were retrospectively retrieved from all public hospitals in Hong Kong. The epidemiological data of 15 participating hospitals were analysed. RESULTS A total of 11 309 anti-HCV+ patients were identified and the estimated diagnosis rate was 50.9%. Our HCV-infected patients were ageing (median age 59). The all-cause mortality rate increased from 26.2 to 54.8 per 1000 person-years over the last decade. Our estimated treatment rate was 12.4%. Among the treated patients, 93.6% had received pegylated interferon/ribavirin (Peg-IFN/RBV) but only 10.8% had received interferon-free direct-acting antivirals (DAAs). In a cohort of 1533 patients, 39% already had advanced liver fibrosis or cirrhosis. The sustained virological response rate for Peg-IFN/RBV and DAAs were 74.8% and 97.2% respectively. However, more than 70% of patients were not subjected to interferon treatment for various reasons. Patients who achieved SVR were associated with a significantly lower risk of HCC (4.7% vs 9.6%, P = 0.005) and death (1.7% vs 23.8%, P < 0.001). CONCLUSION Our diagnosis rate, treatment rate and mortality rate reduction were still low, particularly the Peg-IFN outcomes, making it difficult to meet the WHO hepatitis elimination targets. A more generalized use of DAAs is urgently needed to improve the situation.

Abstract
Hepatitis C virus (HCV) infection, defined by active carriage of HCV RNA, affects nearly 1.0% of the worldwide population. The main risk factors include unsafe injection drug use and iatrogenic infections. Chronic HCV infection can promote liver damage, cirrhosis and hepatocellular carcinoma (HCC) in affected individuals. The advent of new second-generation, direct-acting antiviral (DAA) agents allow a virological cure in more than 90% of treated patients, and therefore prevent HCV-related complications. Recently, concerns have been raised regarding the safety of DAA-regimens in cirrhotic patients with respect to the occurrence and the recurrence of HCC. Here, we review the current available data on HCV epidemiology, the beneficial effects of therapy, and discuss the recent controversy with respect to the potential link with liver cancer. We also highlight the challenges that have to be overcome to achieve the ambitious World Health Organization objective of HCV eradication by 2030.

Abstract
INTRODUCTION Treatment of Hepatitis C Virus (HCV) with direct acting antivirals (DAAs) is able to achieve the cure of infection in almost the totality of patients, independently of the characteristics of the individual and the virus, using short treatment schedules, and without the need of ribavirin. The high cost of DAAs is the main limiting factor for universal treatment of HCV. However, there is a strong evidence that treatment of infection at the early stage of disease may be the most rewarding approach. Areas covered: This review evaluates the aspects underlying the benefit of treating chronic HCV infection at the early stage of disease. It outlines the considerations that have to be taken into account when planning treatment in patients with HCV and minimal liver disease, assessing the positive reflex of viral eradication on several HCV-associated extra-hepatic conditions such as the risk of lymphoma, insulin-resistance and glycaemic control, and renal function. Lastly, it also covers the improvement of patients' quality of life and the pharmaco-economic aspects associated with early treatment. Expert commentary: Treatment of patients with HCV and minimal liver disease is associated with a beneficial, pleiotropic effect of viral eradication that goes beyond the simplistic consideration of the improvement in liver disease-related outcomes.

Abstract
Due to the introduction of newer, more efficacious treatment options, there is a pressing need for policy makers and public health officials to develop or adapt national hepatitis C virus (HCV) control strategies to the changing epidemiological landscape. To do so, detailed, country-specific data are needed to characterize the burden of chronic HCV infection. In this study of 17 countries, a literature review of published and unpublished data on HCV prevalence, viraemia, genotype, age and gender distribution, liver transplants and diagnosis and treatment rates was conducted, and inputs were validated by expert consensus in each country. Viraemic prevalence in this study ranged from 0.2% in Hong Kong to 2.4% in Taiwan, while the largest viraemic populations were in Nigeria (2 597 000 cases) and Taiwan (569 000 cases). Diagnosis, treatment and liver transplant rates varied widely across the countries included in this analysis, as did the availability of reliable data. Addressing data gaps will be critical for the development of future strategies to manage and minimize the disease burden of hepatitis C.

Abstract
Hepatitis C virus (HCV) is a major global public health issue, with an estimated 71 million people living with HCV infection and a rising burden of cirrhosis, hepatocellular carcinoma (HCC) and liver-related mortality. The advent of interferon-free, direct acting antiviral-based (DAA) therapies, with short duration (8-12 weeks), high efficacy, excellent tolerability and ease of delivery (once daily oral dosing), is one of the major advances in clinical medicine in recent decades, and provides the opportunity to address this growing global HCV burden. In May 2014, January 2015 and December 2015, three supplements were published in the Journal of Viral Hepatitis presenting data from 47 countries on the historical epidemiology of HCV, the current HCV-related morbidity and mortality and potential strategies to manage the HCV disease burden in the future. The countries included in those manuscripts were from multiple regions including North and South America, Europe, Asia, the Middle East, Africa and Oceania. In this supplement, data from an additional 17 countries are presented, following a similar pattern as in the previous manuscripts. These countries represent a mixture of high-, middle- and low-income countries that hail from five geographical regions: Africa, Asia, Europe, Middle East and South America. Expert advisory panels were convened in each country to identify the best data sources to use and to review the assumptions and outputs from the model. In the countries considered in the current analyses, there is a wide variance in the availability of robust data.

Abstract
The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 17 countries in Africa, Asia, Europe, Latin America and the Middle East, and interventions for achieving the Global Health Sector Strategy on viral hepatitis targets-"WHO Targets" (65% reduction in HCV-related deaths, 90% reduction in new infections and 90% of infections diagnosed by 2030) were considered. Scaling up treatment and diagnosis rates over time would be required to achieve these targets in all but one country, even with the introduction of high SVR therapies. The scenarios developed to achieve the WHO Targets in all countries studied assumed the implementation of national policies to prevent new infections and to diagnose current infections through screening.
