Role Of Library Professionals In Satisfying User Needs During Pandemic Phase, Sumaira Baba, Sofi Gh.Mohiuddin Jeelani, Dr Shabir Ahmed Ganaie

Library Philosophy and Practice (e-journal)

Libraries are considered as treasures of knowledge providing access to huge variety of materials (books, journals, manuscripts, audio/visual etc.) with the help of institutions to which these (libraries) are associated. But, the preservation of such knowledge (material) is also of prime importance in order to make these resources (material) available for information seekers. In this whole process of collection, storage as well as dissemination of (knowledge), library professionals (librarians) has a great role to play. Which cannot be separated at any cost. Even at the time of pandemic, their (library professionals) role need to be very much vibrant to benefit …

The Problem With Relying On Profit-Driven Models To Produce Pandemic Drugs, Ana Santos Rutschman

All Faculty Scholarship

The longstanding problems of relying on a market response to a pandemic are becoming readily apparent in the United States, which has quickly become the epicenter of the COVID-19 outbreak. The problems are particularly pronounced in pharmaceutical markets, where we are pinning our hopes for both cures and vaccines. In previous work we have shown how characteristics of healthcare markets in the United States create a divergence between the private incentives of for-profit companies and public health needs, leading to sub-optimal health outcomes in what is a uniquely market-driven healthcare system. In this Essay, written as the COVID-19 pandemic unfolds, …

The Reemergence Of Vaccine Nationalism, Ana Santos Rutschman

Protecting The Rights Of People With Disabilities, Elizabeth Pendo

All Faculty Scholarship

One in four Americans — a diverse group of 61 million people — experience some form of disability (Okoro, 2018). On average, people with disabilities experience significant disparities in education, employment, poverty, access to health care, food security, housing, transportation, and exposure to crime and domestic violence (Pendo & Iezzoni, 2019). Intersections with demographic characteristics such as race, ethnicity, gender, and LGBT status, may intensify certain inequities. For example, women with disability experience greater disparities in income, education, and employment (Nosek, 2016), and members of under-served racial and ethnic groups with disabilities experience greater disparities in health status and access …

Mers-Cov Infection In South Korea And Strategies For Possible Future Outbreak: Narrative Review, Chulwoo Park

Faculty Publications

Although there were some positive viewpoints from international press and academia that the Republic of Korea (hereafter South Korea) successfully controlled the Middle East Respiratory Syndrome (MERS) outbreak in 2015, the domestic point of view towards the MERS response in South Korea was critical. As people in the world’s 11th largest economy, South Koreans criticized the failure of hospitals’ initial response to the MERS index case and the lack of a proper control strategy for secondary and tertiary cases. To contain the MERS outbreak, South Korea implemented mainly three MERS control and intervention strategies: quarantine and isolation system, temporary closure …

Bat Coronaviruses In China, Yi Fan, Kai Zhao, Zheng-Li Shi

KIP Articles

During the past two decades, three zoonotic coronaviruses have been identified as the cause of large-scale disease outbreaks–Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS), and Swine Acute Diarrhea Syndrome (SADS). SARS and MERS emerged in 2003 and 2012, respectively, and caused a worldwide pandemic that claimed thousands of human lives, while SADS struck the swine industry in 2017. They have common characteristics, such as they are all highly pathogenic to humans or livestock, their agents originated from bats, and two of them originated in China. Thus, it is highly likely that future SARS- or MERS-like coronavirus outbreaks …

Longitudinal Study Of Age-Specific Pattern Of Coronavirus Infection In Lyle’S Flying Fox (Pteropus Lylei) In Thailand, Supaporn Wacharapluesadee, Prateep Duengkae, Aingorn Chaiyes

KIP Articles

Bats are natural reservoirs for several highly pathogenic and novel viruses including coronaviruses (CoVs) (mainly Alphacoronavirus and Betacoronavirus). Lyle’s flying fox (Pteropus lylei)‘s roosts and foraging sites are usually in the proximity to humans and animals. Knowledge about age-specific pattern of CoV infection in P. lylei, prevalence, and viral shedding at roosts and foraging sites may have an impact on infection-age-structure model to control CoV outbreak. P. lylei bats were captured monthly during January–December 2012 for detection of CoV at three areas in Chonburi province; two human dwellings, S1 and S2, where few fruit trees were located with an open …

Surveying Host Innate Immune Responses To Interferon Antagonist-Deficient Murine Coronaviruses, Aaron Brian Volk

Master's Theses

Two coronaviruses (CoVs)—severe acute respiratory syndrome (SARS) virus and Middle East respiratory syndrome (MERS) virus—have emerged in the 21st century from animal reservoirs into the human population, each causing an epidemic associated with significant disease and mortality. CoV epidemics are currently only controllable by rigorous public health measures; no targeted therapeutics or vaccines exist to treat or prevent any human CoV infection. One method of generating attenuated CoV strains to be studied as vaccine candidates involves specifically disrupting CoV-encoded interferon (IFN) antagonists, thereby rendering the virus vulnerable to host innate antiviral immunity. Deubiquitinating (DUB) activity encoded within CoV nonstructural protein …

Further Evidence For Bats As The Evolutionary Source Of Middle East Respiratory Syndrome Coronavirus, S. J. Anthony, K. Gilardi, V. D. Menachery

KIP Articles

The evolutionary origins of Middle East respiratory syndrome (MERS) coronavirus (MERS-CoV) are unknown. Current evidence suggests that insectivorous bats are likely to be the original source, as several 2c CoVs have been described from various species in the family Vespertilionidae. Here, we describe a MERS-like CoV identified from a Pipistrellus cf. hesperidus bat sampled in Uganda (strain PREDICT/PDF-2180), further supporting the hypothesis that bats are the evolutionary source of MERS-CoV. Phylogenetic analysis showed that PREDICT/PDF-2180 is closely related to MERS-CoV across much of its genome, consistent with a common ancestry; however, the spike protein was highly divergent (46% amino acid …

Surveillance Of Emerging Livestock Viruses, Faten A. Okda

Electronic Theses and Dissertations

Accurate and rapid diagnostic tests are essential for the management and control of emerging infectious diseases. Therefore, the overall goals of studies presented in this dissertation were to provide improved diagnostic and surveillance capabilities for several emerging viral diseases impacting the livestock industry and to provide insight into appropriate control strategies. Recent, severe outbreaks of porcine epidemic diarrhea virus (PEDV) in Asia and North America highlighted the need for well-validated diagnostic tests for identification of PEDV infected animals and evaluation of their immune status. PEDV was first detected in the U.S. in May 2013 and another swine coronavirus, porcine deltacoronavirus …

A Bat-Derived Putative Cross-Family Recombinant Coronavirus With A Reovirus Gene, Canping Huang, William J. Liu, Wen Xu

KIP Articles

The emergence of severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002 and Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012 has generated enormous interest in the biodiversity, genomics and cross-species transmission potential of coronaviruses, especially those from bats, the second most speciose order of mammals. Herein, we identified a novel coronavirus, provisionally designated Rousettus bat coronavirus GCCDC1 (Ro-BatCoV GCCDC1), in the rectal swab samples of Rousettus leschenaulti bats by using pan-coronavirus RT-PCR and next-generation sequencing. Although the virus is similar to Rousettus bat coronavirus HKU9 (Ro-BatCoV HKU9) in genome characteristics, it is sufficiently distinct to be classified as a new …

Genetic Diversity Of Coronaviruses In Miniopterus Fuliginosus Bats, Jiang Du, Xianwen Ren, Junpeng Zhang

KIP Articles

Coronaviruses, such as severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus, pose significant public health threats. Bats have been suggested to act as natural reservoirs for both these viruses, and periodic monitoring of coronaviruses in bats may thus provide important clues about emergent infectious viruses. The Eastern bent-wing bat Miniopterus fuliginosus is distributed extensively throughout China. We therefore analyzed the genetic diversity of coronaviruses in samples of M. fuliginosus collected from nine Chinese provinces during 2011–2013. The only coronavirus genus found was Alphacoronavirus. We established six complete and five partial genomic sequences of alphacoronaviruses, which revealed that …

Symptom Experience And Influenza-Like Illness In A Military Population, Monique Bouvier

Dissertations

AIMS: The primary objective of this study was to identify if symptom presentation expressed over the course of an influenza-like illness (ILI) can predict virus type by use of unsupervised machine learning. The secondary objective was to describe clinical characteristics of strain specific coronavirus. Finally, examine the psychometric properties of the Canadian Acute Respiratory Illness and Flu Scale (CARIFS).

BACKGROUND: ILI outbreaks have been a significant source of non-battle injury among military personnel. Many different viruses cause ILI, and it is difficult to determine which virus is causing the illness. Recent studies have examined the etiology and epidemiology of ILIs. …

Host Species Restriction Of Middle East Respiratory Syndrome Coronavirus Through Its Receptor, Dipeptidyl Peptidase 4, Neeltje Van Doremalen, Kerri L. Miazgowicz, Shauna Milne-Price, Trenton Bushmaker, Shelly Robertson, Dana Scott, Joerg Kinne, Jason S. Mclellan

Dartmouth Scholarship

Middle East respiratory syndrome coronavirus (MERS-CoV) emerged in 2012. Recently, the MERS-CoV receptor dipeptidyl peptidase 4 (DPP4) was identified and the specific interaction of the receptor-binding domain (RBD) of MERS-CoV spike protein and DPP4 was determined by crystallography. Animal studies identified rhesus macaques but not hamsters, ferrets, or mice to be susceptible for MERS-CoV. Here, we investigated the role of DPP4 in this observed species tropism. Cell lines of human and nonhuman primate origin were permissive of MERS-CoV, whereas hamster, ferret, or mouse cell lines were not, despite the presence of DPP4. Expression of human DPP4 in nonsusceptible BHK and …

Generally, the disease starts with a high fever, headaches, body aches, and mild respiratory symptoms. SARS spreads through respiratory droplets produced by an infected person when he or she coughs or sneezes or through physical contact.

The disease was first identified in a southern province of China in November of 2002, and quickly spread to twenty-seven different countries. In March of 2003, the World Health Organization (WHO) declared SARS a global health threat. In China, the economic and social …

Development Of A Safe Neutralization Assay For Sars-Cov And Characterization Of S-Glycoprotein, Dong P. Han, Hyung G. Kim, Young B. Kim, Michael W. Cho

Faculty Scholarship

The etiological agent of severe acute respiratory syndrome (SARS) has been identified as a novel coronavirus SARS-CoV. Similar to other coronaviruses, spike (S)-glycoprotein of the virus interacts with a cellular receptor and mediates membrane fusion to allow viral entry into susceptible target cells. Accordingly, S-protein plays an important role in virus infection cycle and is the primary target of neutralizing antibodies. To begin to understand its biochemical and immunological properties, we expressed both full-length and ectodomain of the protein in various primate cells. Our results show that the protein has an electrophoretic mobility of about 160–170 kDa. The protein is …
