Mathematical modeling was employed on recent epidemiological data from Mexico in order to assess the impact of intervention strategies on the spread of influenza A(H1N1)v in the setting of the ...European region. Active surveillance that will ensure timely treatment and home isolation of symptomatic cases in combination with school closure seem to form an efficient strategy to control the spread of influenza A(H1N1)v.
Summary
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.

Summary
Hepatitis C virus (HCV) infection is a major public health problem in the European Union (EU). An estimated 5.6 million Europeans are chronically infected with a wide range of variation in ...prevalence across European Union countries. Although HCV continues to spread as a largely “silent pandemic,” its elimination is made possible through the availability of the new antiviral drugs and the implementation of prevention practices. On 17 February 2016, the Hepatitis B & C Public Policy Association held the first EU HCV Policy Summit in Brussels. This summit was an historic event as it was the first high‐level conference focusing on the elimination of HCV at the European Union level. The meeting brought together the main stakeholders in the field of HCV: clinicians, patient advocacy groups, representatives of key institutions and regional bodies from across European Union; it served as a platform for one of the most significant disease elimination campaigns in Europe and culminated in the presentation of the HCV Elimination Manifesto, calling for the elimination of HCV in Europe by 2030. The launch of the Elimination Manifesto provides a starting point for action in order to make HCV and its elimination in Europe an explicit public health priority, to ensure that patients, civil society groups and other relevant stakeholders will be directly involved in developing and implementing HCV elimination strategies, to pay particular attention to the links between hepatitis C and social marginalization and to introduce a European Hepatitis Awareness Week.

Summary
Accurate diagnosis and treatment rates for chronic hepatitis B (HBV) and C virus (HCV) infections are usually missing. Aim of this study was to estimate the HBV and HCV treatment cascade ...(proportion and absolute numbers of tested, aware/unaware, infected and treated) in Greek adults. A telephone survey was conducted in a sample representative of the Greek adult general population. Prevalence rates were age‐standardized for the Greek adult population and corrected for high‐risk individuals not included in the survey. Of the 9974 participants, 5255 (52.7%) had been tested for HBV and 2062 (20.7%) for HCV with the proportion varying according to age and being higher in middle‐age groups (P < 0.001). HBsAg was reported positive in 111/5255 (2.11%) and anti‐HCV in 26/2062 (1.26%) tested cases. The age‐adjusted prevalence was estimated to be 2.39% for HBV and 1.79% for HCV. Taking into account individuals at high risk for viral hepatitis not included in the survey, the ‘true’ prevalence was estimated to be 2.58% for HBV and 1.87% for HCV. Anti‐HBV and anti‐HCV treatment had been taken by 36/111 (32.4%) chronic HBV and 15/26 (57.7%) chronic HCV patients. In conclusion, almost 50% of chronic HBV and 80% of chronic HCV patients in Greece may be unaware of their infection, while only 32% or 58% of diagnosed chronic HBV or HCV patients, respectively, have been ever treated. Therefore, intensive efforts are required to improve the efficacy of screening for HBV and particularly for HCV as well as to reduce the barriers to treatment among diagnosed patients.

A cross-sectional telephone survey on a nationally representative sample of 1,000 Greek households was performed to assess the acceptability of the pandemic influenza A(H1N1)v vaccine, factors ...associated with intention to decline and stated reasons for declining vaccination. The survey was initiated the last week of August 2009 (week 35) and is still ongoing (analysis up to week 44). The percentage of participants answering they would probably not/definitely not accept the vaccine increased from 47.1% in week 35 to 63.1% in week 44 (test for trend: p<0.001). More than half of the people which chronic illnesses (53.3%) indicated probably not/definitely not. Factors associated with intention to decline vaccination were female sex, age between 30-64 years, perception of low likelihood of getting infected or of low risk associated with influenza, and absence of household members suffering from chronic illnesses. For the majority of the respondents (59.8%), the main reason for intending to decline vaccination was the belief that the vaccine might not be safe. Promotion of vaccination programmes should be designed taking into account the attitudinal barriers to the pandemic vaccine.
HIV is responsible for one of the largest viral pandemics in human history. Despite a concerted global response for prevention and treatment, the virus persists. Thus, urgent public health action, ...utilizing novel interventions, is needed to prevent future transmission events, critical to eliminating HIV. For public health planning to prove effective and successful, we need to understand the dynamics of regional epidemics and to intervene appropriately. HIV molecular epidemiology tools as implemented in phylogenetic, phylodynamic and phylogeographic analyses have proven to be powerful tools in public health planning across many studies. Numerous applications with HIV suggest that molecular methods alone or in combination with mathematical modelling can provide inferences about the transmission dynamics, critical epidemiological parameters (prevalence, incidence, effective number of infections, Re, generation times, time between infection and diagnosis), or the spatiotemporal characteristics of epidemics. Molecular tools have been used to assess the impact of an intervention and outbreak investigation which are of great public health relevance. In some settings, molecular sequence data may be more readily available than HIV surveillance data, and can therefore allow for molecular analyses to be conducted more easily. Nonetheless, classic methods have an integral role in monitoring and evaluation of public health programmes, and should supplement emerging techniques from the field of molecular epidemiology.
Importantly, molecular epidemiology remains a promising approach in responding to viral diseases.

HIV/HCV prevention among people who inject drugs (PWID) is of key public health importance. We aimed to assess the impact of COVID-19 and associated response measures on HIV/HCV prevention services ...and socio-economic status of PWID in high-HIV-risk sites. Sites with recent (2011–2019) HIV outbreaks among PWID in Europe North America and Israel, that had been previously identified, were contacted early May 2020. Out of 17 sites invited to participate, 13 accepted. Semi-structured qualitative site reports were prepared covering data from March to May 2020, analyzed/coded and confirmed with a structured questionnaire, in which all sites explicitly responded to all 103 issues reported in the qualitative reports. Opioid maintenance treatment, needle/syringe programs and antiretroviral treatment /hepatitis C treatment continued, but with important reductions and operational changes. Increases in overdoses, widespread difficulties with food and hygiene needs, disruptions in drug supply, and increased homelessness were reported. Service programs rapidly reformed long established, and politically entrenched, restrictive service delivery policies. Future epidemic control measures should include mitigation of negative side-effects on service provision and socio-economic determinants in PWID.

Worldwide, the hepatitis B virus (HBV) and the hepatitis C virus (HCV) cause, respectively, 600 000 and 350 000 deaths each year. Viral hepatitis is the leading cause of cirrhosis and liver cancer, ...which in turn ranks as the third cause of cancer death worldwide. Within the WHO European region, approximately 14 million people are chronically infected with HBV, and nine million people are chronically infected with HCV. Lack of reliable epidemiological data on HBV and HCV is one of the biggest hurdles to advancing policy. Risk groups such as migrants and injecting drug users (IDU) tend to be under‐represented in existing prevalence studies; thus, targeted surveillance is urgently needed to correctly estimate the burden of HBV and HCV. The most effective means of prevention against HBV is vaccination, and most European Union (EU) countries have universal vaccination programmes. For both HBV and HCV, screening of individuals who present a high risk of contracting the virus is critical given the asymptomatic, and thereby silent, nature of disease. Screening of migrants and IDUs has been shown to be effective and potentially cost‐effective. There have been significant advances in the treatment of HCV and HBV in recent years, but health care professionals remain poorly aware of treatment options. Greater professional training is needed on the management of hepatitis including the treatment of liver cancer to encourage adherence to guidelines and offer patients the best possible outcomes. Viral hepatitis knows no borders. EU Member States, guided by the EU, need to work in a concerted manner to implement lasting, effective policies and programmes and make tackling viral hepatitis a public health priority.

A significant increase (more than 10-fold) in the number of newly diagnosed HIV-1 infections among injecting drug users (IDUs) was observed in Greece during the first seven months of 2011. Molecular ...epidemiology results revealed that a large proportion (96%) of HIV-1 sequences from IDUs sampled in 2011 fall within phylogenetic clusters suggesting high levels of transmission networking. Cases originated from diverse places outside Greece supporting the potential role of immigrant IDUs in the initiation of this outbreak.
