588 | Which new genus was the virus later found to represent? | [
"Title: Evolution of Genome Size and Complexity in the Rhabdoviridae\nPassage: Five of the novel viruses identified in this study were assigned to established genera. Two of these, KOOLV and YATV, clustered within the existing Ephemerovirus clade, and possessed the characteristic genome organization of ephemeroviruses, including a non-structural glycoprotein gene followed by a viroporin Newly proposed genera are indicated by a † symbol. Cytorhabdovirus, novirhabdovirus and nucleorhabdovirus outgroup sequences were excluded from the tree as they were too divergent to establish a reliable rooting. The tree is therefore rooted arbitrarily on one of two basal clades that comprise viruses isolated from mosquitoes.",
"Title: Serious Invasive Saffold Virus Infections in Children, 2009\nPassage: During the past few years, intensive searches for new viruses, using conventional virologic methods and metagenomics, have resulted in the discovery of several new viruses. During the past decade, the family Picornaviridae has grown as the number of recognized genera has increased from 6 to 12 ; the numbers of species, types, and subtypes have increased even more. However, only viruses from 3 genera have been fi rmly established as being capable of causing clinically signifi cant disease in humans. Viruses from other genera have so far been detected only in noninvasively collected human sample material such as fecal and",

The contig contained a single long ORF that showed greatest similarity to members of the genus Phlebovirus, and the currently unclassified GOUV which was originally detected in specimens of the mosquito genera Anopheles , Culex and Uranotaenia in West Africa. Here, we provide evidence for a related novel virus from mosquitoes collected in France. Further field studies are necessary to allow the potential full isolation of this strain, which considering its divergence from GOUV, may constitute a novel genus within"

1427 | What does infection of respiratory viruses cause? | [
"Title: Nasopharyngeal Protein Biomarkers of Acute Respiratory Virus Infection\nPassage: Acute respiratory viral infections are among the most common reasons for patient visits in primary and acute care settings . Many viruses cause such acute respiratory illness including human rhinovirus , respiratory syncytial virus and influenza. These viruses can be associated with a range of clinical severity from asymptomatic to mild, self-limited illness to respiratory failure and death. Influenza alone causes 25 to 50 million infections annually in the USA, resulting in several hundred thousand hospitalizations and 20-40,000 deaths .",
"Title: Respiratory Viral Infections in Exacerbation of Chronic Airway Inflammatory Diseases: Novel Mechanisms and Insights From the Upper Airway Epithelium\nPassage: Another mechanism that viral infections may use to drive acute exacerbations is the induction of vasodilation or tight junction opening factors which may increase the rate of infiltration. Infection with a multitude of respiratory viruses causes disruption of tight junctions with the resulting increased rate of viral infiltration. This also increases the chances of allergens coming into contact with airway immune cells. For example, IFV infection was found to induce oncostatin M which causes tight junction opening . Similarly, RV and RSV infections usually cause tight junction opening which may also increase the infiltration rate of eosinophils and thus worsening",
"Title: Overview of the 3rd isirv-Antiviral Group Conference – advances in clinical management\nPassage: Human rhinoviruses usually cause mild acute respiratory infections, but on occasions can also cause more severe respiratory infections, including exacerbations of asthma and COPD. Of 115 Japanese children with asthma, a respiratory virus was detected in 86%, of which HRV or RSV were most common. 79 Ex vivo bronchial epithelial cells from people with asthma are more susceptible to HRV infection, due to deficient induction of IFN-b and IFN-lambda. In a study of 147 asthmatics on inhaled corticosteroid therapy, with a history of virusassociated exacerbations, patients were randomised to 14-day treatment with inhaled IFN-b or placebo within 24 hours of",
"Title: Severe Acute Respiratory Infections With Influenza and Noninfluenza Respiratory Viruses: Yemen, 2011-2016\nPassage: Acute respiratory infections are a group of diseases that are caused by different microorganisms where viral etiologies are responsible for 80% of cases. 1 Influenza and noninfluenza viruses are responsible for significant annual morbidity and mortality across all age groups. 2 On average, influenza viruses infect 5% to 15% of the global population, resulting in 3 to 5 million cases of severe illness and between 260 000 and 650 000 deaths every year worldwide. The heaviest burden is among high-risk groups that include pregnant women, children under 59 months, the elderly, individuals with chronic medical conditions. 3 In 2015, it"

"Title: Respiratory Viral Infections in Exacerbation of Chronic Airway Inflammatory Diseases: Novel Mechanisms and Insights From the Upper Airway Epithelium\nPassage: Another mechanism that viral infections may use to drive acute exacerbations is the induction of vasodilation or tight junction opening factors which may increase the rate of infiltration. Infection with a multitude of respiratory viruses causes disruption of tight junctions with the resulting increased rate of viral infiltration. This also increases the chances of allergens coming into contact with airway immune cells. For example, IFV infection was found to induce oncostatin M which causes tight junction opening . Similarly, RV and RSV infections usually cause tight junction opening which may also increase the infiltration rate of eosinophils and thus worsening",

"Title: MERS coronavirus: diagnostics, epidemiology and transmission\nPassage: Individual human case studies report long periods of viral shedding, sometimes intermittently and not necessarily linked to the presence of disease symptoms. In one instance, a HCW shed viral RNA for 42 days in the absence of disease . It is an area of high priority to better understand whether such cases are able to infect others. Over three quarters of MERS cases shed viral RNA in their LRT specimens for at least 30 days, while only 30 % of contacts were still shedding RNA in their URT specimens .",
"Title: MERS coronavirus: diagnostics, epidemiology and transmission\nPassage: The WHO recommends sampling from the LRT for MERS-CoV RT-rtPCR testing, especially when sample collection is delayed by a week or more after onset of symptoms. LRT samples are also best for attempting isolation of infectious virus, although the success of culture is reduced when disease persists . Recommended sample types include bronchoalveolar lavage , tracheal/tracheobronchial aspirate, pleural fluid and sputum . Fresh samples yield better diagnostic results than refrigerated material and if delays in testing of ≥72 h are likely, samples should be frozen at −70°C . If available, lung biopsy or autopsy tissues can also be tested .",
"Title: MERS coronavirus: diagnostics, epidemiology and transmission\nPassage: The URT is a less invasive and more convenient sampling site however, and an oropharyngeal and throat swab or a nasopharyngeal aspirate/wash are recommended when URT sampling is to be conducted . Paired sera, collected two to three weeks apart are preferable for serological testing while a single sample is suggested to be sufficient if collected two weeks after onset of disease or a single serum collected during the first 10-12 days if conducting RT-rtPCR . Human urine and stool have been found to contain MERS-CoV RNA 12 to 26 days after symptom onset and are listed as samples that",
"Title: MERS coronavirus: diagnostics, epidemiology and transmission\nPassage: In the only study to examine the effect of sample type on molecular analysis, 64 nasopharyngeal aspirates , 30 tracheal aspirates, 13 sputa and three BAL were examined. The tracheal aspirates and BAL returned the highest viral load values followed by NPA and sputum. Unsurprisingly, higher viral loads generally paralleled whole genome sequencing and culture success and, in NPA testing, were significantly correlated with severe disease and death . This study demonstrated the importance of LRT sampling for whole genome sequencing."

In addition, CQ could inhibit SARS-CoV entry through changing the glycosylation of ACE2 receptor and spike protein 6 . Time-of-addition experiment confirmed that HCQ effectively inhibited the entry step, as well as the post-entry stages of SARS-CoV-2, which was also found upon CQ treatment .

Regardless of treatment, no differences were observed in the pathogenesis of HPS-like disease in ANDV-infected hamsters. Hamsters in all groups exhibited signs of mild to moderate inflam- mation, interstitial pneumonia, alveolar fibrin deposition, and edema characteristic of ANDV infection.",
"Title: Hantaviruses in the Americas and Their Role as Emerging Pathogens\nPassage: The ANDV-Syrian hamster model has a number of features in common with the human disease, as well as some differences. Unlike the neurologic diseases that have been possible to elicit with HTNV, the hamster model for HCPS appears to be caused by capillary leak that results in pulmonary edema and the production of a pleural effusion with exudative characteristics. Typically the hamsters die between 11 and 14-d post-inoculation, reflecting a slightly accelerated incubation period in comparison to human infections. As with human HCPS, the microscopic examination of the lung reveals abundant fibrin deposition, thickened alveolar septa, and viral antigen expressed",
"Title: Hantaviruses in the Americas and Their Role as Emerging Pathogens\nPassage: Compared to the human disease, ANDV-infected hamsters exhibit exceptionally high titers of live ANDV in their tissues, with much of the viral replication occurring in hepatocytes, which are spared in the human disease. Titers of live ANDV in some cases exceed 10 8 /g, whereas hantavirus isolates from human tissues have been notoriously difficult to obtain.

The necessary levels of latrine and bore hole coverages needed to eradicate the epidemic are both around 16 to 18%. Although the cost of construction of the required number of latrines is a one off cost, the benefits are large.

"Title: The Dynamics, Causes and Possible Prevention of Hepatitis E Outbreaks\nPassage: Our model suggests that to eradicate the epidemic, the minimum number of additional latrines required is 3,47. The average cost of digging and constructing a basic pit latrine is approximately USD 250.00 Therefore, 3,477 would cost a total of USD 869,250.00. Thus, the cost per disability adjusted life year averted in Kitgum, in the case of Hepatitis E is 869,250/7,066 = USD 123.00. In addition to improving hygiene we should consider education.

First, it is assumed that if the people had the necessary and sufficient number of latrines in addition to safe drinking, then the outbreak would not have occurred. Then, the costs of constructing the required latrines and boreholes are computed. From the results, the cost of saving one life from Hepatitis E, for one year is determined."

RANBP2 is associated with microtubules and mitochondria suggesting roles in intracellular protein trafficking or energy maintenance and homeostasis of neuronal cells. RANBP2 mutations have been reported in acute necrotizing encephalopathy which could present with coma, convulsions, and encephalopathy. The hallmark of ANE is multiple, symmetric brain lesions located in the thalami bilaterally, putamina, deep periventricular white matter, cerebellum, and brainstem. It could be triggered by a viral infection in previously healthy children .",

This mutation has not been previously reported in the HGMD database. This variant has been observed at a frequency of <0.01% across the entire Broad ExAC dataset of individuals without severe childhood onset disease . Analysis of amino acid conservation indicates that the wild-type amino acid Lys1665 is conserved in 59 of 60 mammals examined, including 12 of 12 primates, and in 25 of 34 nonmammalian vertebrates increasing the likelihood that a change at this position might not be tolerated.

"Title: Human core duplicon gene families: game changers or game players?\nPassage: The RANBP2 protein encoded by the progenitor gene is primarily localized within the periphery of the nuclear envelope and is thought to be required for cargo import and export . Hence, the RGPD gene family members may be modifiers of this function. Interestingly, RANBP2 was also shown to be involved in resistance against Simian Immunodeficiency Virus . It is thus possible that the expansion of RGPD genes is the result of an arms race between virus evolution and host resistance acquisition. The Ranbp2 knockout in mice is homozygous lethal.",

Previously healthy patients with pathogenic mutations in RANBP2 can present acutely with encephalopathy and convulsions in the context of an infection, with brain imaging revealing involvement of the brainstem, thalami, putamina, cerebellum and external capsules, and claustrum .

"Title: Acute Hemorrhagic Encephalitis Responding to Combined Decompressive Craniectomy, Intravenous Immunoglobulin, and Corticosteroid Therapies: Association with Novel RANBP2 Variant\nPassage: RANBP2, a nuclear pore protein, has numerous roles in the cell cycle. RANBP2 is associated with microtubules and mitochondria suggesting roles in intracellular protein trafficking or energy maintenance and homeostasis of neuronal cells. RANBP2 mutations have been reported in acute necrotizing encephalopathy which could present with coma, convulsions, and encephalopathy. The hallmark of ANE is multiple, symmetric brain lesions located in the thalami bilaterally, putamina, deep periventricular white matter, cerebellum, and brainstem. It could be triggered by a viral infection in previously healthy children .",
"Title: Acute Hemorrhagic Encephalitis Responding to Combined Decompressive Craniectomy, Intravenous Immunoglobulin, and Corticosteroid Therapies: Association with Novel RANBP2 Variant\nPassage: A gene panel targeting inflammatory disorders and post-infectious necrotic encephalopathies found a heterozygous RANBP2 missense mutation . This mutation has not been previously reported in the HGMD database. This variant has been observed at a frequency of <0.01% across the entire Broad ExAC dataset of individuals without severe childhood onset disease . Analysis of amino acid conservation indicates that the wild-type amino acid Lys1665 is conserved in 59 of 60 mammals examined, including 12 of 12 primates, and in 25 of 34 nonmammalian vertebrates increasing the likelihood that a change at this position might not be tolerated. In silico tools",
"Title: Human core duplicon gene families: game changers or game players?\nPassage: The RANBP2 protein encoded by the progenitor gene is primarily localized within the periphery of the nuclear envelope and is thought to be required for cargo import and export . Hence, the RGPD gene family members may be modifiers of this function. Interestingly, RANBP2 was also shown to be involved in resistance against Simian Immunodeficiency Virus . It is thus possible that the expansion of RGPD genes is the result of an arms race between virus evolution and host resistance acquisition. The Ranbp2 knockout in mice is homozygous lethal.",
"Title: Acute Hemorrhagic Encephalitis Responding to Combined Decompressive Craniectomy, Intravenous Immunoglobulin, and Corticosteroid Therapies: Association with Novel RANBP2 Variant\nPassage: Autosomal dominant mutations in RANBP2 have been associated with susceptibility to infectioninduced necrotizing encephalopathy . Previously healthy patients with pathogenic mutations in RANBP2 can present acutely with encephalopathy and convulsions in the context of an infection, with brain imaging revealing involvement of the brainstem, thalami, putamina, cerebellum and external capsules, and claustrum . Our patient has a similar presentation and imaging features as infection-induced necrotizing encephalopathy, including bilateral thalamic involvement. The rare heterozygous previously unreported variant we identified in RANBP2 affects a very conserved aminoacid and is predicted deleterious using in silico tools . It is possible that this variant"

"Title: Age-Specific Excess Mortality Patterns During the 1918–1920 Influenza Pandemic in Madrid, Spain\nPassage: Spain experienced one of the highest excess mortality rates during the 1918 influenza pandemic in Europe , although this country did not take part in World War I. Perhaps this pandemic outcome is associated with the fact that Spain was going through a demographic transition and experiencing elevated death rates that were only comparable to those of eastern Europe. Of note, the life expectancy in Spain was 41 years in 1910 and 40 years in 1920 ."

"Title: Host resilience to emerging coronaviruses\nPassage: Both SARS-CoV and MERS-CoV are typified by a rapid progression to ARDS, however, there are some distinct differences in the infectivity and pathogenicity. The two viruses have different receptors leading to different cellular tropism, and SARS-CoV is more ubiquitous in the cell type and species it can infect. SARS-CoV uses the ACE2 receptor to gain entry to cells, while MERS-CoV uses the ectopeptidase DPP4 .

To address these limitations, long-term follow-up studies would be required to identify sufficient positive samples with associated clinical data. Increasing the scale of surveillance would also help, though there are practical geographical and logistic constraints in our locality.",
"Title: Recent Progress in Studies of Arterivirus- and Coronavirus-Host Interactions\nPassage: The pathogenicity of these viruses is typically species-dependent, as is the severity of infection; they infect mainly their natural hosts and/or species that are closely related. Certain virus infections, however, can cross the species barrier, with the prime example being the zoonotic SARS-CoV, a novel coronavirus that is thought to have originated from bats before it adapted to its intermediate host, civet cats, and finally to humans . Bat colonies, which are scattered worldwide, are widely known to play host to a variety of coronaviral and adenoviral pathogens while acting as natural wildlife reservoirs of these viruses .",
"Title: Finding and identifying the viral needle in the metagenomic haystack: trends and challenges\nPassage: approaches is overspecificity, which makes classification of unknown sequences problematic. This limitation can be particularly acute given the known very high intraspecific variability existing in some viral species or higher order taxa. For example, current criteria of the International Committee for the taxonomy of viruses tolerate up to 28% of nucleotide sequence divergence for the polymerase or capsid protein genes for isolates of a same species in the Betaflexiviridae family and a similar level of divergence at the whole genome level in the Potyviridae family .",

"Title: Variation in RNA Virus Mutation Rates across Host Cells\nPassage: genetic andmetabolic alterations in addition to p53 inactivation. To check the potential effects of these changes, we performed fluctuation tests in CT26 cells from an undifferentiated grade IV colon adenocarcinoma of a BALB/c mouse , but we found no significant differences with primary MEFs . Of note, BHK-21 are also tumor-forming cells, and the mutation rate was similar to the rate observed in MEFs or CT26 cells . This homogeneity in the VSV mutation rate was not an obvious a priori, because metabolic and mitotic activity should alter the availability of NTPs and hence could impact RNA replication fidelity, although",

The incidence in high-income countries is estimated at 0.015 episodes per child year, compared to 0.22 episodes per child year in low-and middle-income countries . On average, 1 in 66 children in high-income countries is affected by pneumonia per year, compared to 1 in 5 children in low-and middle-income countries.
