    • Description:
      "Epidemics of influenza-like disease are presently subsiding in most affected areas in the Eastern and Middle Western United States. Two localized outbreaks, one of them confirmed as influenza A2, have thus far been reported from northern California. No community-wide outbreaks of influenza-like illness have been recognized in any of the Pacific coast States to date. One or more outbreaks of influenza-like disease have been reported from the District of Columbia and 41 States. Since publication of the Influenza Surveillance Report of March 8, 1963, the following additional States have reported one more outbreaks for the first time: Alaska, California, Colorado, Idaho J New Hampshire, North Dakota, and Utah. Influenza A2 virus has been isolated or confirmed by serologic titer rise as the causative agent in one or more outbreaks in the District of Columbia and 32 States. The following States have reported laboratory confirmation of outbreaks for the first time since publication of the March 8 report: Arizona, Arkansas, California, Colorado, Indiana, Kentucky, Louisiana, Missouri, Montana, North Dakota., Pennsylvania, Rhode Island, Tennessee, Vermont, and West Virginia. The pattern of epidemic spread continued to show some evidence of a westerly course during March, although the extensive, often statewide involvement which characterized earlier outbreaks on the Eastern Seaboard, was not frequently observed as the epidemic moved westward. Additional outbreaks of moderate severity were reported from the States of Ohio, Indiana, West Virginia, Tennessee, Louisiana, Texas and North Dakota. Among the Mountain States, Arizona, Colorado, Idaho, and Utah reported new outbreaks, while on the Pacific Coast only two localized outbreaks in northern California have been reported (See above). In addition to this westward spread, a significant number of outbreaks have occurred in the eastern States of Maine, Vermont, New Hampshire and Pennsylvania during the past month. Pneumonia-influenza deaths in the 108 cities, which first exceeded the epidemic threshold in early January, reached a peak during the week ending March 16 and have been declining during the past three weeks, although still remaining above epidemic threshold. Studies conducted on selected influenza outbreaks during the current season have failed to demonstrate markedly elevated attack rates in the age group 10-19 as was consistently found in similar studies done during the 1957 epidemic. Moderately severe epidemics of influenza-like illness were reported from the following countries at about the same time that outbreaks were occurring in the United States: France, Federal Republic of Germany, Italy, Jamaica, Norway, Portugal, Sweden, Switzerland, and the United Kingdom." - p.
