    • Description:
      "Influenza and pneumonia mortality for 108 cities has decreased again this week. Although this is the fourth week of decline since the peak of March 1 mortality is still significantly above the five year seasonal average. Assuming that the mortality was related to Asian influenza in special population groups seems probable that deaths will shortly reach normal levels. This would be the natural result of the advent of this would be the natural result of the advent of warm weather and exhaustion of susceptibles. There is still evidence of sporadic small outbreaks of influenza proved by virus isolation, but these are being reported in decreasing numbers. Dr. Widelock, et al, of New York City Health Department have reported the isolation of a variant Asian strain. This variant reacts with FM-1 as well as Asian antibodies in the H-I test. There is no evidence that this variant has been responsible for recent outbreaks or that it has increased virulence. An epidemic of influenza is reported to be occurring in Hong Kong." - p. 2
