Description:
"With confirmation of the Grinnell, Iowa, outbreak as Far East strain influenza, a chain of infection is described which commences with an outbreak at Davis, California, extends to Grinnell, Iowa, and to now confirmed cases in Kentucky and suspect cases in New Mexico, Illinois, Indiana, Connecticut, and Colorado. Although no significant spread of the virus outside of special population groups has yet been reported, a general seeding of the Far East stain influenza virus throughout the United States is certainly occurring. Far East stain influenza virus has also been confirmed in the foreign-exchange students visiting in Salt Lake City, Utah. These students began their bus tour in San Francisco, an area where a number of focal outbreaks has been reported. At the International Boy Scout Jamboree, Valley Forge, Pennsylvania, an influenza-like illness has to date affected about 350 of the 53,000 scouts. These cases are occurring primarily among California delegates, who began noting cases en route. In several instances a single individual or known contacts have given rise to subsequent focal outbreaks. In this instance, again, the "provoking factor" of crowding in trains and buses appears to be important in the spread of infection. Cases among Illinois and Indiana scouts seem closely related to the proximity of a Los Angeles group during a train trip from New York to Valley Forge. No generalized outbreak is presently apparent. The lack of crowding in close quarters in this pup tent encampment may impair further spread of the illness. Far East stain influenza virus has been confirmed in the numerous areas indicated by the appended map. Laboratory confirmation of cases is pending in several widely separated areas. An influenza associated death in California is described in this report. Laboratory studies are not yet complete but the impression at post-mortem examination was that the death due to a toxic myocarditis with acute circulatory collapse and cardiac failure. Additional details will be presented as they are made available." - p. [1]
