The incidence rate for respiratory illness was 125.9 per 100 persons during the 12 months ending in June 1966, compared with a rate of 116.4 during the previous year. Contributing to the increased incidence of respiratory illness was an epidemic of influenza-like illnesses totaling 83.3 million conditions. The incidence rate for conditions reported as influenza was 43.7 per 100 persons, about 30 percent higher than the rate of 33.9 per 100 persons during the year ending in June 1965. During the current year there was a reduction in reporting of injuries involving activity restriction or medical attention. An estimated 48.4. million injuries occurred, or 25.4 injuries per 100 persons, This rate represents a drop of 15 percent from the rate of injury of 29.9 for the preceding year, This decline in rate may be an artifact due to change in questionnaire format, variations in reporting, or unusual sampling variability (see explanation on pages 3 and 5).
