"From September 1972 to September 1973, influenza reached epidemic proportions in major areas of the United States. As in the 1971-1972 influenza season, widespread outbreaks occurred in a number of states. In nearly all influenza A outbreaks, a virus similar to A2/England/42/72 (H3N2) was demonstrated to be the responsible agent. Regionally, the greatest morbidity and mortality was seen in the Pacific, Mountain, Middle Atlantic, East North Central, and West South Central regions. Nine states reported localized outbreaks of influenza B: Arizona, California, Colorado, Hawaii, Idaho, Minnesota, Oregon, Washington, and Wisconsin. In 3 of these (Hawaii, Washington, and Minnesota) hemagglutinin inhibition tests revealed an antigenic shift from previous B isolates in the United States. This report summarizes the morbidity and mortality data received by the Center for Disease Control (CDC) for the 1972-1973 influenza season." - p. [1]
