Document Summary

1 two types: a causes major epidemics, b causes mild diseases. 2 produce hemagglutinin and grow well in cell culture. 3 their nucleic acids are separate but connected together, resulting in frequent recombination the resulting antigenic variability explains periodic appearance of new types of virus that cause pandemics of influenza. 4 clinical: acute febrile illness with variable respiratory symptoms b) Infants and elderly are particularly sensitive to both diseases and complications. 5 diagnosis: throat washing or nasopharyngeal aspirate taken within 3 days after onset b) If patients can"t gargle, use throat and nasal swabs. 6 serum: paired sera taken within 2~3 weeks (acute and convalescent phase) to investigate the increase in titer of antibodies, acute sample must be collected as soon as after onset c) 2 cause respiratory diseases that have severe complications. 5 no vaccine: respiratory syncytial viruses (rsv) 1 major respiratory pathogen in children under age 2. 4 antiviral available but no vaccine: rhinoviruses.
