Abstract
In 2015, more than 1 million asylum seekers and refugees arrived in Europe. Information on how European countries addressed the prevention and control of infectious diseases among these populations during and after this period is limited. This study is based on 27 semi-structured interviews conducted with first-line staff and health officials in May–June 2016 in first-entry countries (Greece/Italy), transit countries (Croatia/Slovenia) and destination countries (Austria/Sweden). Characteristics of health-service provision for infectious diseases at each stage of reception, with a focus on tuberculosis, viral hepatitis, intestinal parasites and human immunodeficiency virus infections, were investigated. No major differences in the provision of services in accordance with migration status (asylum seekers vs refugees) were reported. At arrival, interventions were focused on addressing emerging health needs and no major barriers to accessing acute hospital care for infectious diseases were reported. There were shortcomings in interventions to tackle medium- to long-term needs with respect to infectious diseases, including screening for chronic treatable infections and adult vaccination. European evidence-based guidance highlighting the most relevant interventions for infectious diseases during the reception process is needed.
International audience ; Background: Highly infectious diseases (HIDs) are defined as being transmissible from person to person, causing life-threatening illnesses and presenting a serious public health hazard. The sampling, handling and transport of specimens from patients with HIDs present specific bio-safety concerns.

The Crimean-Congo hemorrhagic fever virus (CCHFV) is considered to be a major emerging infectious threat, according to the WHO R&D blueprint. A wide range of CCHFV molecular assays have been developed, employing varied primer/probe combinations. The high genetic variability of CCHFV often hampers the efficacy of available molecular tests and can affect their diagnostic potential. Recently, increasing numbers of complete CCHFV genomic sequences have become available, allowing a better appreciation of the genomic evolution of this virus. We summarized the current knowledge on molecular methods and developed a new bioinformatics tool to evaluate the existing assays for CCHFV detection, with a special focus on strains circulating in different geographical areas. Twenty-two molecular methods and 181 sequences of CCHFV were collected, respectively, from PubMed and GenBank databases. Up to 28 mismatches between primers and probes of each assay and CCHFV strains were detected through in-silico PCR analysis. Combinations of up to three molecular methods markedly decreased the number of mismatches within most geographic areas. These results supported the good practice of CCHFV detection of performing more than one assay, aimed for different sequence targets. The choice of the most appropriate tests must take into account patient's travel history and geographic distribution of the different CCHFV strains. ; Funding: This research was supported by the following funds: Italian Ministry of Health, grants Ricerca Corrente–Linea 1; European Union, Joint Action Consumers, Health, Agriculture, and Food Executive Agency for E cient response to highly dangerous and emerging pathogens at EU level no. 677066 (EMERGE); European Centre for Disease Prevention and Control (ECDC), EVD-LabNet Framework contract ECDC/2016/00; European Union, Horizon 2020 research and innovation program "European Virus Archive goes Global" no. 653316 (EVAg). ; Sí

Action on social determinants is a main component of the World Health Organization End Tuberculosis (TB) Strategy. The aim of the study was to collect information on socioeconomic characteristics and biomedical risk factors in migrant TB patients in Italy and compare it with data collected among Italian TB patients. A cross-sectional study was conducted among TB patients aged ≥18 years over a 12-months enrolment period in 12 major Italian hospitals. Information on education, employment, housing and income was collected, and European Union Statistics on Income and Living Conditions index was used to assess material deprivation. Among migrants, we also analyzed factors associated with severe material deprivation. Migrants were compared with younger (18-64 years) and older (65+ years) Italians patients. Out of 755 patients enrolled (with a median age of 42 years, interquartile range: 31-53), 65% were migrants. Pulmonary, microbiologically confirmed, and new cases were 80%, 73%, and 87% respectively. Prevalence of co-morbidities (i.e. diabetes, chronic kidney disease, neoplastic diseases and use of immunosuppressive drugs) was lower among migrants compared to Italian TB patients, while indicators of socioeconomic status, income and housing conditions were worst in migrants. Forty-six percent of migrants were severely deprived vs. 9% of Italians (p<0.0001, 11.3% and 5.5% among younger and older Italians, respectively). Among migrants, being male, older, irregular, unemployed, with a shorter time spent in Italy, a lower education level, and without a co-morbidity diagnosis were factors associated with severe material deprivation at multi-variable logistic regression. Moreover, socioeconomic indicators for Italian patients did not differ from those reported for the general Italian population, while migrant TB patients seem to have a higher prevalence of severe material deprivation than other migrants residing in Italy. Intervention to address the needs of this population are urgent.
The identification of monkeypox in 3 separate patients in the United Kingdom in September raised media and political attention on an emerging public health threat. Nigeria, whose last confirmed case of monkeypox was in 1978, is currently experiencing an unusually large and outbreak of human monkeypox cases, a 'One Human-Environmental-Animal Health' approach is being effectively used to define and tackle the outbreak. As of 13th October 2018, there have been one hundred and sixteen confirmed cases the majority of whom are under 40 years. Over the past 20 years ten Central and West African countries have reported monkeypox cases which have risen exponentially. We review the history and evolution of monkeypox outbreaks in Africa and USA, the changing clinical presentations, and discuss possible factors underlying the increasing numbers being detected including the cessation of smallpox vaccination programs. Major knowledge gaps remain on the epidemiology, host reservoir, and emergence, transmission, pathogenesis and prevention of monkeypoz.

World TB Day, March 24th commemorates the day in March 1882 when Professor Robert Koch made the groundbreaking announcement in Berlin of his discovery of Mycobacterium tuberculosis as the cause of Tuberculosis (TB) (Koch, 1882). At the time of his announcement, there was a deadly TB epidemic, rampaging throughout Europe and the Americas, causing the death of one out of every seven people. Since Koch's announcement, Mycobacterium tuberculosis has defied worldwide efforts by public health systems, researchers, governments and the World Health Organization (WHO) to eradicate it. The data presented in the WHO Global TB Report 2017 (World Health Organization, 2017a) makes very gruesome reading. In 2016 there were an estimated 10.4 million people who developed TB disease worldwide, of which 90% were adults, 35% female and 10% were HIV-co-infected people. An estimated 40% of active TB cases go undiagnosed each year. One hundred and thirty-six years since Koch's announcement, TB remains a major global public health issue and TB has surpassed HIV/AIDS and malaria as the world's top cause of death from an infectious disease! On World TB Day, March 24th, 2018, we need to reflect on the current status quo of the continuing devastating global TB epidemic.

BackgroundCrimean-Congo haemorrhagic fever virus (CCHFV) is considered an emerging infectious disease threat in the European Union. Since 2000, the incidence and geographic range of confirmed CCHF cases have markedly increased, following changes in the distribution of its main vector, Hyalomma ticks.AimsTo review scientific literature and collect experts' opinion to analyse relevant aspects of the laboratory management of human CCHF cases and any exposed contacts, as well as identify areas for advancement of international collaborative preparedness and laboratory response plans.MethodsWe conducted a literature review on CCHF molecular diagnostics through an online search. Further, we obtained expert opinions on the key laboratory aspects of CCHF diagnosis. Consulted experts were members of two European projects, EMERGE (Efficient response to highly dangerous and emerging pathogens at EU level) and EVD-LabNet (Emerging Viral Diseases-Expert Laboratory Network).ResultsConsensus was reached on relevant and controversial aspects of CCHF disease with implications for laboratory management of human CCHF cases, including biosafety, diagnostic algorithm and advice to improve lab capabilities. Knowledge on the diffusion of CCHF can be obtained by promoting syndromic approach to infectious diseases diagnosis and by including CCHFV infection in the diagnostic algorithm of severe fevers of unknown origin.ConclusionNo effective vaccine and/or therapeutics are available at present so outbreak response relies on rapid identification and appropriate infection control measures. Frontline hospitals and reference laboratories have a crucial role in the response to a CCHF outbreak, which should integrate laboratory, clinical and public health responses. ; This work was supported by the Health programme 2014–2020, from the European Commission; EMERGE Joint Action grant number: 677066.

Soon after the novel coronavirus, SARS-CoV-2 (2019-nCoV), was first identified in a cluster of patients with pneumonia (Li et al., 2020), in the Chinese city of Wuhan on 31 December 2019, rapid human to human transmission was anticipated (Hui et al., 2020). The fast pace of transmission is wreaking havoc and stirring media hype and public health concern (Ippolito et al., 2020) globally. When the World Health Organization (WHO) declared the disease, (now officially named COVID-19) a Public Health Emergency of International Concern (PHEIC) on 31st January 2020 (WHO, 2020a), the Director General Dr Tedros Ghebreyesus justified the decision by stating that WHOs greatest concern was the potential for the virus to spread to countries with weaker health systems. Repeated outbreaks of other preventable emerging and re-emerging infectious diseases with epidemic potential have taken their toll on the health systems of many African countries. The devastating 2014–2016 Ebola Virus Epidemic (WHO, 2020b) in West Africa, demonstrated how ill-prepared the affected countries were to rapidly identify the infection and halt transmission (WHO, 2020d, Largent, 2016, Hoffman and Silverberg, 2018, Omoleke et al., 2016). Similarly, the smoldering remnants of the 2018–19 Ebola Virus outbreak in the Democratic Republic of Congo, have demonstrated even for health services with considerable experience of dealing with a certain emerging pathogen, geography and sociopolitical instability, can hamper the response (Aruna et al., 2019).
