  • Alternative Title:
    Influenza : Asian strain – 1957 : Confirmed cases ; Confirmed and suspect outbreaks [map, August 16, 1957] ; Proposed voluntary vaccine allocation system ;
  • Description:
    "Included in this Report is a daily record of patients seen with influenza-like illnesses at Charity Hospital, in New Orleans. It is hoped that eventually, by comparison with previous years; figures, some estimation of current morbidity due to influenza may be obtained. Additional enumerations from other areas will be added as they become available. Evidence of infection with Asian strain has been reported from Oregon, with a camp outbreak of febrile respiratory disease also noted in the same area. An Oregon Boy Scout, who attended the Jamboree at Valley Forge, yielded this strain, also. Asian strain influenza virus has been isolated from cases in an upstate New York labor camp and from foreign exchange students in New York city. One death has occurred in this later group. Probably the first report this season of influenza virus isolated from a fatal case of complicating staphylococcal pneumonia has come from California. Evidence of influenza infection due to an A-prime virus has been obtained from a sporadic case in New Orleans, Louisiana. Seed virus and fluid antigen of an egg-animal-line of influenza virus has been distributed by the Influenza Virus Center at Montgomery, Alabama. It is expected that hemagglutination-inhibition tests will be facilitated by this material. Asian strain virus has been isolated from influenza patients in Colombia, South America. A/Denver/57 related strains have been implicated in several influenza cases which occurred in Saskatchewan, Canada. As has been frequently observed recently, Asian strain influenza virus is widely "seeded" over the country. The mildness of the illness, coupled with the infrequency of diagnostic specimens, probably has resulted in only a very small percentage of cases being identified. What holds the virus in abeyance at this season is far from clear." - p. 2
