  • Description:
    "Epidemics of influenza-like disease are presently widespread in several areas of the Eastern United States. The first confirmed outbreak of influenza of the current season began in early January in Robeson County in southern North Carolina. Since that time, outbreaks of influenza-like disease have been reported from the District of Columbia and 15 States, including North Carolina, Maryland, Virginia, Delaware, Kansas, Illinois, Georgia, Maine, Vermont, South Carolina, New York, Massachusetts, Ohio, Kentucky and West Virginia. Influenza A2 virus has been isolated or confirmed as causative agent by serologic titer rise in outbreaks in the District of Columbia, North Carolina, Maryland, Kansas, New York, and at the Great Lakes Naval Training Station in Illinois. During the month of January, the pattern of spread of disease tended to confine itself to both a northerly and southerly course along the Atlantic seaboard. The confirmed outbreaks of influenza in the Kansas City and Chicago areas occurred in rather specialized population groups, and community spread in these areas has not been apparent. Since the beginning of February, the outbreak of influenza-like disease in West Virginia, Kentucky, and Ohio has suggested the beginning of a westerly spread. To date, the Pacific Coast, Southwest and Rocky Mountain areas of the country, as well as the major portion of the Middle West and South, have not been involved. Pneumonia-influenza deaths have been above the epidemic threshold for the last 5 weeks with a sharp upswing in excess deaths for the week ending February 9. Excess pneumonia-influenza deaths have shown particular increases in the South and Middle Atlantic States during this week." - p. [1]
