• severe
  • While sometimes confused with the common cold, influenza is a much more severe disease and is caused by a different type of virus. (wikipedia.org)
  • Influenza spreads around the world in a yearly outbreak, resulting in about three to five million cases of severe illness and about 250,000 to 500,000 deaths. (wikipedia.org)
  • The type A viruses are the most virulent human pathogens among the three influenza types and cause the most severe disease. (wikipedia.org)
  • antigenic
  • As a result of this lack of antigenic diversity, a degree of immunity to influenza B is usually acquired at an early age. (wikipedia.org)
  • The virus then avoids detection because the antibodies released will be ineffective in binding to the new antigenic sites on the modified HA and NA proteins - ultimately the host doesn't recognize the modified virus. (studymode.com)
  • But, the virus is more feared for its significant mutation due to the process of antigenic shift. (studymode.com)
  • deaths
  • According to American Medical Association (H1N1 news, n.d.), as of November 12, 2009, data from April 2009 through October 17, 2009 indicates that: there is a total of 20 million people became ill with H1N1, 98,000 hospitalized, and 3,900 deaths. (studymode.com)
  • New cases and deaths attributable to Ebola virus disease (EVD) continue to be reported by the Ministries of Health in the three West African countries of Guinea, Liberia, and Sierra Leone. (tropnet.eu)
  • and Sierra Leone, 305 cases (269 confirmed, 34 probable, and 2 suspected) and 127 deaths (114 confirmed, 11 probable, and 2 suspected). (tropnet.eu)
  • 5. June 2014: cumulatively the total number of cases and deaths attributable to Ebola virus disease in Guinea is 351 (210 laboratory-confirmed, 83 probable, and 58 suspected) including 226 deaths. (tropnet.eu)
  • species
  • Experts have identified key events (creating new clades, infecting new species, spreading to new areas) marking the progression of an avian flu virus towards becoming pandemic, and many of those key events have occurred more rapidly than expected. (wikipedia.org)
  • Serological evidence of H5-subtype influenza A virus infection in indigenous avian and mammalian species in Korea. (amedeo.com)
  • Transmission of H6N2 wild bird-origin influenza A virus among multiple bird species in a stacked-cage setting. (amedeo.com)
  • These subtypes are known to circulate preferably in specific bird species which possess sialic acid linked to oligosaccharides via alpha (2,3) linkages, such as chickens, turkeys, and ducks. (biomedcentral.com)
  • infectious
  • Flu viruses can remain infectious for about one week at human body temperature, over 30 days at 0 °C (32 °F), and indefinitely at very low temperatures (such as lakes in northeast Siberia). (wikipedia.org)
  • Influenza, commonly known as "the flu", is an infectious disease caused by an influenza virus. (wikipedia.org)
  • Under greenhouse or laboratory settings, evaluation for resistance or susceptibility to CMD involves transmission of the causal viruses from an infected source to healthy plants through grafting, or by using Agrobacterium-mediated or biolistic delivery of infectious clones. (scoop.it)
  • protein
  • 9. The virus as claimed in the claim 8, wherein the marker gene is Enhanced Green Fluorescent Protein (EGFP) gene. (patentsencyclopedia.com)
  • Influenza viruses are classified into 3 different types (A,B,C) and influenza A is further divided into specific subtypes named after the respective combination of surface protein variants pairing 1 of 17 hemagglutinins (the "H" in HxNx) with 1 of 10 neuraminidases (the "N" in HxNx). (biomedcentral.com)
  • surveillance
  • The global HPAI situation significantly improved in the first half of 2008, but the FAO reports that imperfect disease surveillance systems mean that occurrence of the virus remains underestimated and underreported. (wikipedia.org)
  • No doubt, this case was picked up due to enhanced surveillance for the H7N9 virus after the outbreak in China, and the subsequent importation of a case to Taiwan in April. (blogspot.com)
  • gene
  • The invention further relates to a recombinant modified vaccinia Ankara (MVA) virus comprising and capable of simultaneously expressing a cassette of not less than two foreign genes from influenza virus, wherein the said genes are inserted at a non-essential site, within the MVA genome, with the provision that at least one foreign gene is either PB2 or M2e. (patentsencyclopedia.com)
  • 8. The virus as claimed in claim 2, wherein a marker gene is cloned along with the influenza genes. (patentsencyclopedia.com)
  • 14. The virus as claimed in the claim 2, wherein each gene of the influenza virus is under the transcriptional control of separate P11 promoters. (patentsencyclopedia.com)
  • Here we report a rapid screening system for determining resistance and susceptibility to CMD based on virus-induced gene silencing (VIGS) of an endogenous cassava gene. (scoop.it)
