    "During the 6 month interval since the publication of the last CDC Influenza Surveillance Report in May, 1959, the occurrence of influenza in the United States has been extremely limited, both in distribution and frequency. The laboratory confirmed cases are tabulated by States in Section II, the majority of these reports were received in early and mid-summer, and, although no dates of onset are included in the laboratory reports, the predominance of Type B infections and the time suggest that most of these cases represent the last few sporadic infections of the Type B outbreaks last spring. As of this date there is no evidence that influenza is again becoming active in the United States. The analysis of influenza and pneumonia deaths from 108 selected cities, detailed in Section III, reveals an essentially normal curve, with no significant excesses in influenza and pneumonia mortality, Elsewhere during the summer months, widespread outbreaks were reported from Central and South America, Australia, the Philippines, India, and Africa. These reports are presented in Section IV. The outbreaks in the Far East and Western Pacific were primarily due to type A2, whereas those occurring in the Americas were of a mixed etiology, A2 and B. The present Public Health Service policy regarding influenza immunization is defined in a statement by the Surgeon General, appearing in Section V. Selected groups are described for whom influenza vaccination may be desirable, As the current influenza season begins, this CDC Influenza Surveillance Report will again be published regularly, with a frequency as determined by the extent and nature of occurrence of influenza this winter." - p. 2
