  • Description:
    "Clinically, confirmed cases of Far East strain influenza continue to be notably mild. Duration of illness in the teen-age and young adult groups, most heavily affected to date, has been about two-to-three days. Associated complications have been exceptionally uncommon. Secondary cases among contacts under normal circumstances have been rare, as noted below. Influenza-like illnesses among Grinnell delegates recently returned home have occurred in New York, Connecticut, Mississippi, Illinois, New Mexico, Indiana, Minnesota, and Colorado. Many cases undoubtedly have occurred in other areas. But few secondary cases have been reported from Grinnell or from other areas to which students returned. Conditions at present do not appear favorable for the explosive spread of influenza. At the International Boy Scout Jamboree no general outbreak has occurred despite the probable presence of influenza in several of the groups. Sporadic cases of febrile respiratory illness have occurred in each of the 38 sections of the camp. Fourteen hundred boys are tented in a section. During the first five days of the Jamboree, daily hospital admissions have remained at a nearly constant figure. Febrile respiratory disease has represented 60 to 80% of total admissions. If conditions relative to crowding do serve as a "provoking factor", the trip home for some of these 53,000 scouts may produce further localized outbreaks. An additional sporadic civilian case of Far East strain influenza from Cleveland, Ohio, is noted in the present report. This and other indications suggest a rather wide but still inapparent disbtribution of Far East strain influenza virus." - p. [1]
