Filetype[PDF-1.45 MB]

  • Description:
    "Since the last report (No. 40, April 15) the number of deaths from influenza and pneumonia has been consistently declining in the 108 cities reporting to NOVS, except for a minor increase in the week ending May 24. The number of deaths during this week for all Divisions is approximately two-thirds of what it was six weeks ago. The impact of the epidemic on mortality from influenza and pneumonia and from all causes can be visualized in the graph showing the mortality by week during the period August '57-May '58. The second wave of mortality from all causes in the winter of '58 was higher than the first wave in the fall of '57. The reverse is true in so far as deaths from influenza and pneumonia are concerned. Considering the distribution of deaths from all causes by age groups, the two mortality waves are clearly distinguishable in the groups 1-64 and 65 and over, the latter being the most affected. Deaths under one year remained at a constant level daring this period. A study of monthly mortality rates, estimated from a 10% sample of death certificates received by NOVS, for the period 1951-57, shows that the death rate from influenza in the fall of '57 was about 7O% of the death rate in the winter of 1953, while the death rates from pneumonia were practically the same in 1951, '53 and '57." - p. 2

    May 29, 1958. "This will be the last report of these series. Although the surveillance of acute respiratory diseases will continue as a routine function of CDC, no reports will be issued until an unusual prevalence of these diseases will warrant the distribution of this type of information again. We wish to take this opportunity to thank once more all those who contributed so effectively in making the influenza surveillance program operative in assessing the trend of the disease in this country during the 1957-58 epidemic." - p. 2 "For official use only; not for publication." - cover "Information contained in this report is a summary of data reported to CDC by State Health Departments, Epidemic Intelligence Service Officers, collaborating influenza diagnostic laboratories, and other pertinent sources.
