UCDAVIS 27/08/20 Amazon and Congo Basin Focus of New Emerging Infectious Disease Research Center - $8M to UC Davis to Investigate Viral Emergence and Spillover in Vulnerable Forest Regions. OUVRAGE EN LIGNE - 2020 - Emerging and reemerging viral pathogens. GLOBAL ECOLOGY ANE BIOGEOGRAPHY 19/12/19 Distinct spread of DNA and RNA viruses among mammals amid prominent role of domestic species. Pathogen spillover and cross‐species transmission between animals and humans is a major source of infectious diseases and a considerable global public health burden (Jones et al., 2008; Karesh et al., 2012). Understanding the factors that enable or facilitate these processes is a crucial step for such events to be predicted. Host shifting, that is the colonization of a new host species by a pathogen, requires a certain level of overlap in species traits (“ecological fitting”) in order to overcome barriers of cross‐species transmission and for survival and reproduction within novel host species (Agosta, Janz, & Brooks, 2010; Parrish et al., 2008; Woolhouse, Haydon, & Antia, 2005).

Nevertheless, despite important advances in virus discovery and analytical approaches, our understanding of virus sharing and their spread through entire networks of mammalian host species remains limited. 2.1 Virus–host data 2.2 Mammalian host phylogeny and ecological trait data 2.3 Statistical analysis.

THE ROYAL SOCIETY 08/04/20 Global shifts in mammalian population trends reveal key predictors of virus spillover risk. 1. Introduction Infectious diseases that originate from animals and infect people comprise the majority of recurrent and emerging infectious disease threats and are widely considered to be one of the greatest challenges facing public health [1–3].

Characterization of pathogen transmission events from wildlife to humans remains an important scientific challenge hampered by pathogen detection limitations in wild species. Disease spillover is probably vastly under-reported, particularly in remote regions where people have limited access to healthcare. Zoonotic disease spillover events are also difficult to detect, especially if the disease spectrum includes mild or non-specific symptoms, or if there is limited to no human-to-human transmission. The synthesis of epidemiological and ecological profiles of viruses and their hosts has enabled the detection of intrinsic virus and host features linked to species propensity to share viruses with humans [5,8]. 2.

List of organisms that require handling with the most severe protocol Biosafety level 4 laboratories are used for diagnostic work and research on easily transmitted pathogens which can cause fatal disease. What follows is a list of organisms that require handling with the most severe protocol. Organisms include those harmful to human health, to animal health, or to plant health.[1] The Plant Protection and Quarantine programs (PPQ) of the Animal and Plant Health Inspection Service (APHIS) are listed in 7 CFR Part 331. The Department of Health and Human Services (HHS) lists are located at 42 CFR Part 73.3[2] and 42 CFR Part 73.4.[3] The USDA animal safety list is located at 9 CFR Subchapter B.[4] Select agents[edit] HHS human threats: select agents and toxins[edit] HHS human or animal threats: select agents and toxins[edit] USDA select agents and toxins[edit] PPQ select agents and toxins[edit] References[edit]

WIKIPEDIA - Emergent virus. Virus that has recently displayed increased pathogenicity or contagion, or has appeared in a new host species left no distinct epidemiological cluescould not be isolated or propagated in culture Zoonosis[edit] Zoonosis – i.e. the spread of infectious disease from animals to humans – is estimated to account for 6 out of 10 infectious diseases in humans.

Viruses (and prions) play a disproportionately large role, and account for approximately 43% of emerging (and re-emerging) human pathogens. As there is little to no occurrence of spontaneous new virus species development, the ability of a virus to ‘jump’ from its natural host is crucial during the establishment of emergent viral diseases. In order to overcome host-range restrictions and to sustain efficient human-human transmission, viruses originating from an animal reservoir frequently undergo mutation and genetic recombination.

Received: 5 September 2019 / Revised: 1 October 2019 / Accepted: 3 October 2019 / Published: 12 October 2019 Round 1 Reviewer 1 Report This review deals with a subject interesting and still topical: the risk of nosocomial transmission of viral infections through aerosol-generating medical procedures (AGMPs) in particular to healthcare workers (HCWs) attending infected patients.

The main aim of this review is to investigate which AGMPs and which viruses are most at risk. As for viruses, the authors focus on emerging viruses highly pathogenic, for which there are limited prophylactic or therapeutic countermeasures. The results reported are based on some, limited, bibliographic citations. As previously stated, the literature citations in support of the content of this review are scarce either in the section of the manuscript concerning the emerging viruses and their transmissibility by aerosol and in the last part in the section 4 concerning designing experiments and assessing risk.

Aron J. VIRUSES - MARS 2020 - Special Issue "Emerging Viruses: Surveillance, Prevention, Evolution and Control"- Deadline for manuscript submissions: 15 September 2020. Dear Colleagues, Emerging viruses represent a major concern for public health offices. Climate changes, the international migration of people and products, deforestation, and other anthropogenic activities (and their consequences) seem to be closely related to the emerging of new viruses, triggering an increasing number of notified outbreaks, epidemics, and pandemics. In this Special Issue, we encourage colleagues to submit manuscripts related to the surveillance, detection, and evolution of emerging viruses, describing from local outbreaks to worldwide viral pandemics.

We also welcome manuscripts describing new methods and technologies adapted or created for the study, prevention, and control of emerging viruses.

Please visit the Instructions for Authors page before submitting a manuscript. Neurological Research and Practice 11/06/19 Emerging and re-emerging viruses affecting the nervous system.

The increased trade, travel habits, urbanization and climate change are some of the factors, which favour evolution and spread of new pathogens. Infectious diseases are emerging or re-emerging every year. Neuroinfectious diseases may occur as outbreaks in small localized regions or may spread rapidly over large geographical areas. An epidemic occurs when an infectious disease spreads rapidly to many people like the Zika Virus outbreak.

A pandemic is a global disease outbreak as seen e.g. in HIV/AIDS. Recent outbreaks caused by Chikungunya-virus, West – Nile-virus, Enterovirus infection and Ebolavirus have caused severe neurological manifestations and spread rapidly across continents. Endemic diseases are constantly present, usually in low numbers. Neurotropic viruses can access the brain via retrograde axonal transport, haematogenous spread crossing the blood-brain-barrier (BBB) or through spread of infected leukocytes across the BBB into the brain parenchyma.

Over the last 30 years, diseases caused by emerging swine viruses (ESV) have acquired great relevance, more than in other species. Diseases caused by porcine reproductive and respiratory syndrome virus (PRRSv), high pathogenicity porcine epidemic diarrhea virus (PEDv), porcine circovirus type 2 (PCV-2), and influenza virus H1N1pdm09 had great economic impact. Others, however, such as porcine enteroviruses, porcine toroviruses (PToV), porcine sapelovirus (PSV), porcine bocavirus (PBoV), porcine kobuvirus (PKBV), and porcine Torque teno sus virus (TTSuV) are mostly subclinical in swine herds. Furthermore, novel emerging viruses, such as SENECA virus, atypical porcine pestivirus (APPV), PCV-3, SADS-CoV, influenza D, and others with regional or worldwide distribution constitute a new challenge for researchers and practicing veterinarians.

Emerging viruses should be considered to occur when there are changes in the relationship between the agent, the host and the enviroment. Review Articles.

INTECH - JANV 2020 - The Emerging Challenges in Transmission and Detection of Filovirus Infections in Developing Countries. 1. Introduction The filovirus infections are emerging new infections, which pose serious public health threats of global dimensions. This filovirus family comprises mainly of the Ebola virus and the Marburg virus. Some five species of Ebola have been confirmed and includes the Zaire Ebola virus (EBOV), the Sudan subtype (SUDV), the Bundibugyo virus (BDBV), the Tai Forest virus (TAFV), and the Reston virus (RESTV) [1, 2].

Most of the outbreaks have been caused by EBOV and SUDV infections. The TAFV has caused single causality. RESTV is associated with asymptomatic infection among nonhuman primates and pigs [3]. The Marburg virus was first isolated in 1967 when laboratory workers in Marburg, Germany and Yugoslavia were infected when exposed to imported green monkeys from Uganda [4, 5]. The Ebola virus was first identified in 1976 in a major outbreak in 1976. 2. The natural history of filoviruses remains rudimentary and largely not well understood. 3. 4. 5. 6. RESPIROLOGY 15/04/19 Emerging respiratory infections threatening public health in the Asia‐Pacific region: A position paper of the Asian Pacific Society of Respirology.

Emerging infectious diseases such as severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), pandemic influenza A(H1N1) 2009 (influenza A(H1N1)pdm09) and avian influenza (AI) pose a threat to global health. Bird and swine influenza viruses continuously obtain new gene segments through reassortment with human strains. Moreover, infections by multidrug‐resistant Gram‐negative bacteria are also increasing worldwide. Hence, action is needed to curtail the dissemination of these organisms. For this position paper, members of the Asian Pacific Society of Respirology (APSR) Respiratory Infections Assembly selected respiratory pathogens that are most likely to pose significant threats to humans, particularly in the Asia‐Pacific region. The members reviewed epidemiological features of the pathogens and put together a consensus opinion.

THE JOURNAL OF TRANSLATIONAL IMMUNOLOGY 16/04/19 Vaccines for emerging pathogens: from research to the clinic. Historically, vaccines have had enormous impact on human health, eradicating smallpox, polio and many other childhood and adult infections of public health concern. Worldwide, attention is now turning to the task of vaccines for these emerging and re‐emerging pathogens, with renewed interest and support from international governments, the World Health Organization (WHO) and organizations such as the Coalition for Epidemic Preparedness Innovations (CEPI), the Global Alliance for Vaccines and Immunization (GAVI) and philanthropic organizations such as the Gates Foundation.

This review series sets out to survey the progress to date. In their article, Afrough, Dowall and Hewson 1 review a range of emerging viruses and make the case for applying molecular techniques to understand viral pathogenesis. Understanding the interaction of the host with a viral pathogen to expedite vaccine development is a theme taken up in the review contributed by Sharpe et al. 2.

The recombinant vesicular stomatitis expressing the GP derived from Zaire EBOV isolate Kikwit in place of the original VSV GP (VSVΔG/EBOV-GP)34 as well as the Zaire EBOV strains Makona and Mayinga, and the NiV strain Malaysia were grown on Vero E6 cells. The viral titers of the Zaire EBOV and NiV strains were determined by limited dilution, using cytopathic effect (CPE) as read out. VSVΔG/EBOV-GP was concentrated by centrifugation for 1 h at 100,000 × g and 4 °C through a 20% (w/v) sucrose cushion and resuspended in DMEM or in phosphate-buffered saline (PBS) for immunizations.
