An Influenza Resistance Information Study (IRIS)
Summary
This study will assist in the early detection of influenza resistant to antivirals, and will monitor the clinical outcome of patients infected with influenza according to subtype and susceptibility. Patients clinically diagnosed with influenza will undergo a rapid diagnostic test, and viral sampling at baseline and on days 3 and 6. Patients will be clinically managed according to local guidelines (no treatment, or treatment with neuraminidase inhibitors or other appropriate therapies).

Medical and Biotech [MESH] Definitions
Influenza B Virus
Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
Hemagglutinin Glycoproteins, Influenza Virus
Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.
Influenza In Birds
Infection of domestic and wild fowl and other BIRDS with INFLUENZA A VIRUS. Avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic POULTRY.
Genetic Testing
Detection of or testing for certain ALLELES, mutations, genotypes, or karyotypes that are associated with genetic traits, heritable diseases, or with a predisposition to a disease, or that may lead to the disease in descendants. It includes prenatal genetic testing.
Anonymous Testing
Testing in which the source of the specimen or the person being tested is not individually identified.
