Description:"At least 652 counties have now reported influenza since the first appearance of the Asian strain virus in the United States. This represents 21.2% of the counties of the nation. Of this number 119 have experienced community-wide epidemics. All sections of the country are more or less involved now although the Plains States, with low population densities, remain least affected. North Dakota remains the only state apparently free of Asian influenza. Industrial reports show increases in absenteeism for 23 of the 36 reporting cities. Pacific Coast and Plains State cites represent the largest number not yet reporting increased absenteeism. Two cities, Phoenix and Cincinnati, which previously reported increased industrial absenteeism have returned to normal rates for this season. First reports of increases continue to occur one to two weeks after the appearance of school outbreaks in the two cities. Summaries of influenza-associated deaths (5 form Ohio, 3 from New Jersey, and 1 from the District of Columbia) are presented in this report. Four of these summaries illustrate the phenomenon of sterile pneumonia. It must be re-emphasized that CDC is not reporting all, or even a large portion, of the influenza-associated deaths in this country. A total of 27,156,487 ml. of Asian strain influenza vaccine has been released through October 24. This includes 4,391,051 ml. released since October 16. Excess mortality for the United States as a whole continues its steady rise. The total excess for all divisions for the week ending October 26 is approximately 400 deaths (using the same week in 1954, 1955, and 1956 for comparison). The greatest relative increases are occurring in the South Atlantic, Middle Atlantic, East North Central, and New England divisions. A somewhat speculative discussion of the spread of Asian strain influenza within the community is includes in the Epidemic and Case Reports section. It is pointed out that many areas have noted that their first outbreaks affected high school children. Elementary school children are affected a few days later, and adults are not involved to any extent for another one or two weeks. Industrial absentee data supports these observations (at least for urban areas)." - p. [2]
