Description:
"Influenza and pneumonia mortality continues to increase for the fourth straight week, despite the absence of widespread influenza outbreaks, Although Asian influenza is still occurring sporadically, this does not sufficiently explain the rising mortality. Clinicians report no apparent change in the virulence of influenza. Extensive efforts are being made to gather supplementary information regarding the nature of the reported deaths. Preliminary examination of mortality data in large cities suggests that most of the deaths are concentrated in the 65 plus age group. Such an age distribution might explain why schools and age group. Such an age distribution might explain why schools and industries have not been affected. This conclusion is far from certain. This conclusion is far from certain, however, and much more information is needed. We urgently request your heap in finding the cause of this increased mortality. Please send us a summary of any recent investigations which may bear on this problem. Health officials in particular are asked to report the nature and extent of recurrent outbreaks. Good clinical data on severe or fatal cases is also needed." - p. 2
