  • Description:
    This document carries final figures on the reported incidence of notifiable diseases in 1975. Data are submitted to the Center for Disease Control by the individual States through the National Morbidity Reporting System and are supplemented by surveillance activities of the Bureau of Epidemiology and Bureau of State Services at CDC, as well as the National Center for Health Statistics, Health Services Administration. Totals for the United States do not include data from Guam, Puerto Rico, and the Virgin Islands. The population figures for 1977 used in computing rates are from the Bureau of the Census and are provisional estimates of the resident population as of July 1, 1977 (Table 1 and table 5). Estimates of the resident population by age are from Current Population Reports, Series P-25, no. 721. Population figures from those States where diseases were not notifiable or where age specific data were not available were excluded from rate calculations. The morbidity data in this report represent cases reported to CDC through State health departments. The accuracy of reporting, that is, the number of cases that are reported to CDC as compared with the actual number that occur, varies with the disease. Some diseases, such as plague and rabies, that cause severe clinical illness and are associated with serious consequences are probably reported fairly completely. Diseases that are clinically mild and infrequently associated with serious consequences, such as salmonellosis and mumps, are less likely to be reported. Additionally, subclinical cases are seldom detected except in the course of special studies. Also, the degree of completeness of reporting is influenced by the diagnostic facilities available, the control measures in effect, and the interests and priorities of State and local officials responsible for disease control and surveillance. The data in this report stem from a variety of reporting mechanisms and motivations that seem to remain consistent; thus the analysis of trends is valid. For example, the age and seasonal distribution of these samples have been shown to be consistent over the years. In order not to delay the publication of this document, we have included provisional data from California. For confirmation of any of those data, contact the California State Department of Health.
