    "This report presents a review of influenza for the seven month period since the last CDC Influenza surveillance Report (No. 41., May 29, 1958) was distributed. The disease has occurred only sporadically since early April when the second wave of excess mortality due to influenza and pneumonia subsided. There is, however, evidence that the new Asian strain has entrenched itself in many parts of the world. To a large extent, indeed, the new strain appears to have replaced other Type A strains. Sporadic Type B infections, however, continue to be reported. In Section II. Dr. Robert Serfling and Mr. Arthur Cohen of the Statistics Section present an extensive discussion of current influenza and pneumonia mortality. A new version of the regional excess mortality graphs (which appeared with most of the influenza reports in 1957-1958) appears as Figure I. in this report, accompanying the current mortality review. Deaths due to influenza and pneumonia remained near expected levels throughout the fall and early winter of 1958. Additional notes on influenza in the United States during the last half of 1958 are included in Section III. References are made to some specific cities and areas which showed small increases of excess mortality above normal levels during the fall of 1958. A review of the small number of reports of influenza outbreaks and isolations from individuals in other parts of the world is presented in isolations from individuals in other parts of the world is presented in the next section. In Section V. the current recommendations regarding influenza vaccination are presented, and studies of effectiveness of Asian influenza vaccine are briefly reviewed and referenced. The final section presents an outline of the current status of the Public Health Service influenza surveillance program.Unless there is a dramatic change in the influenza situation the next Influenza Surveillance report will be prepared at the conclusion of the customary 'influenza season' in the early spring of 1959." - p. 2
