What role does T-cell count play in severe human adenovirus type 55 (HAdV-55) infection?
[ "Title: Emergent severe acute respiratory distress syndrome caused by adenovirus type 55 in immunocompetent adults in 2013: a prospective observational study\nPassage: Recent studies have shown that the immune system plays a crucial role in the clearance of HAdV viremia and survival of the host . Chen et al. reported that, in the acute phase of HAdV-55 infection, patients with severe disease may have high levels of dendritic cells and Th17 cells . In our study, the only patient who recovered from severe infection had higher T-cell counts. Three of the five patients had relatively low T-cell counts when admitted. Our results suggest that these three patients may have been relatively immunocompromised and that a lower T-cell count may be a risk", "Title: Emergent severe acute respiratory distress syndrome caused by adenovirus type 55 in immunocompetent adults in 2013: a prospective observational study\nPassage: Recent studies have shown that the immune system plays a crucial role in the clearance of HAdV viremia and survival of the host .

[ "Title: Asymmetry in the Presence of Migration Stabilizes Multistrain Disease Outbreaks\nPassage: Finally, the work discussed here shows a potential effect of human movement between heterogeneous regions. As spatial effects are further studied in epidemic models, it remains to be seen how this phenomenon will extend to more complicated spatial geometries, including more patches and perhaps non-symmetric coupling terms. This work represents a first step towards understanding the role of migration and spatial heterogeneity in dynamical properties of dengue observed in epidemiological data, such as traveling waves of infection in Thailand . Furthermore, because the migration-induced stabilization depends only on the existence of a Hopf bifurcation in the model, it is expected", "Title: Asymmetry in the Presence of Migration Stabilizes Multistrain Disease Outbreaks\nPassage: Bifurcations from steady state to oscillatory behavior can be associated with an increased number of infection cases, particularly if chaotic oscillations occur, as in previous dengue models . Our results suggest that if control strategies in one region are able to generate enough asymmetry, this could lead to a stabilization of the outbreaks, which would have a positive effect on adjacent regions. Asymmetry could be generated in the effective contact rate by mosquito control, which could include reducing mosquito breeding sites , or through new genetic controls which are under development . Asymmetry in the birth rate could be generated", "Title: Asymmetry in the Presence of Migration Stabilizes Multistrain Disease Outbreaks\nPassage: To motivate this result, we diffusively coupled two low dimensional Hopf bifurcations with different characteristic frequencies and analyzed the stability of the steady state. We again saw that coupling between asymmetric systems led to stabilization. This indicates that the stabilization in the epidemic model is a result of the underlying dynamics, rather than the details of the model. We suggest that the stabilization may occur as a result of the two different coupled frequencies generating oscillations that tend to cancel each other because of phase differences. This topic will be studied in more detail in a future work.", "Title: Globalization and emerging governance modalities\nPassage: cannot afford grain.

Although the S protein of SARS-CoV shares little aminoacid identity , it shares common structural features with S proteins of the other members of the Coronaviridae family.

On 27 November 2002 Chinese-language media and internet reports were picked up by Canada's Global Public Health Intelligence Network that indicated a flu-like illness was occurring in China . Unfortunately, the reports were not translated, and China failed to report the occurrence of this illness to the World Health Organization until February 2003. The disease spread to other countries where", "Title: Molecular and serological investigation of 2019-nCoV infected patients: implication of multiple shedding routes\nPassage: Text: Coronaviruses belong to the subfamily Orthocoronavirinae in the family Coronaviridae and the order Nidovirales. A human coronavirus caused the severe acute respiratory syndrome coronavirus outbreak in 2003. Most recently, an SARS-related CoV was implicated as the etiological agent responsible for the outbreak in Wuhan, central China. This outbreak is estimated to have started on 12th December 2019 and 17,332 laboratory confirmed cases with 361 deaths as of 3rd February 2020 in China . The virus has spread to 23 other countries by travellers from Wuhan . Typical symptoms are fever, malaise, shortness of breath and in severe cases, pneumonia" ]

What types of cells follow epithelial cells in the immune response to infections in the lung?
[ "Title: Differential Response of Primary Alveolar Type I and Type II Cells to LPS Stimulation\nPassage: The alveolar epithelium is an important component of the innate immune response of the lung. By providing an anatomic barrier that separates the organism from the external environment, the alveolar epithelium serves as a first line of defense against potential inhaled pathogens. While the cells of the innate immune system, such as alveolar macrophages and dendritic cells, harbor the bulk of the responsibility for prompting an immune reaction upon encountering inhaled pathogens, the cells that comprise the alveolar epithelium have also been implicated in aiding to trigger an inflammatory response.", "Title: Epithelial Cells Derived from Swine Bone Marrow Express Stem Cell Markers and Support Influenza Virus Replication In Vitro\nPassage: Bone marrow cell therapy may be effective in conditions that currently lack effective treatment.

The newly recognized disease, hantavirus cardiopulmonary syndrome, HCPS , was linked to infection by the newly-discovered Sin Nombre virus , and the rodent Peromyscus maniculatus was identified as the reservoir . However, hantavirus infections have a much longer history.

Seventeen individuals were identified with SNV antibody or were antigen positive out of 52 suspected cases . Major outbreaks due to ANDV occurred in 1996 in southern Argentina ; in southern Chile clusters of patients presented with hantavirus illness in 1997 . In Brazil, the first outbreak was identified in the Brazilian Amazon in 2000, and involved small villages that resulted in a 13.3% prevalence of those tested .", "Title: Hantaviruses in the Americas and Their Role as Emerging Pathogens\nPassage: Hantaviruses are horizontally transmitted between rodents and are not transmitted by arthropods . Spillover infection to nonhuman mammals usually results in no onward transmission, but if humans are infected may result in high morbidity and mortality . During the spring of 1993, an outbreak of patients with HCPS due to SNV occurred in the Four Corners states resulting in more than 60% case-fatality among the initial cases, many involving members of the Navajo tribe . In Panama, an outbreak was reported during 1999-2000 in Los Santos, and 12 cases where identified with three fatalities . This represented the first report", "Title: Hantaviruses in the Americas and Their Role as Emerging Pathogens\nPassage: cases of acute febrile disease with renal compromise were described from several Eurasian countries and Japan, often in association with military engagements . HFRS as a distinct syndrome, however, was first brought to the attention of western medicine in association with an outbreak that occurred among United Nations troops during the Korean conflict between 1951 and 1954, where more than 3,200 soldiers were afflicted .

The newly recognized disease, hantavirus cardiopulmonary syndrome, HCPS , was linked to infection by the newly-discovered Sin Nombre virus , and the rodent Peromyscus maniculatus was identified as the reservoir . However, hantavirus infections have a much longer history. A review of ancient Chinese writings, dating back to approximately 960 AD, revealed descriptions closely resembling hemorrhagic fever with renal syndrome , the syndrome caused by Old World hantaviruses .

In South America, the first largest identified outbreak occurred in the Chaco region in northwestern Paraguay during 1995-1996. Seventeen individuals were identified with SNV antibody or were antigen positive out of 52 suspected cases . Major outbreaks due to ANDV occurred in 1996 in southern Argentina ; in southern Chile clusters of patients presented with hantavirus illness in 1997 . In Brazil, the first outbreak was identified in the Brazilian Amazon in 2000, and involved small villages that resulted in a 13.3% prevalence of those tested .", "Title: Hantaviruses in the Americas and Their Role as Emerging Pathogens\nPassage: Hantaviruses are horizontally transmitted between rodents and are not transmitted by arthropods . Spillover infection to nonhuman mammals usually results in no onward transmission, but if humans are infected may result in high morbidity and mortality . During the spring of 1993, an outbreak of patients with HCPS due to SNV occurred in the Four Corners states resulting in more than 60% case-fatality among the initial cases, many involving members of the Navajo tribe .

How safe is NYVAC?
