Summary tables-cases and outbreaks: Table I. Confirmed outbreaks and cases of influenza due to Far East strains, United States, June 1-July 29, 1957 -- Table II. Unconfirmed influenza-like illness, outbreaks - United States, June 1-July 29, 1957 -- Table III. Outbreaks of febrile respiratory disease - etiology other than influenza or no specimens obtainable, June 1-July 29, 1957 -- Table IV. Reported influenza-like illness among returning delegates from Grinnell (Iowa) Conference through July 29, 1957 -- Table V. Reported outbreaks of influenza-like illness among Boy Scouts returning from Jamboree through July 25, 1957 (see CDC influenza progress report 6-E)

"Further small outbreaks among Boy Scouts returned from the Jamboree. These have been reported from Texas and two areas in Alabama. At least one additional outbreak has been reported from a military facility in California. Another local outbreak of influenza-like illness has occurred among migrant workers in Sonoma County, California. At present, only small groups among these workers have been involved. Due to some difficulty in performing hemagglutination-inhibition tests with currently available antigen, isolates from several outbreaks have so far been grouped only by complement-fixation tests. Influenza A virus has been identified in some outbreaks listed in Table II. These will not be noted until confirmation of Asian strain virus has been obtained." - p. 2
