“…The illnesses recorded had caused a minimum of seven consecutive days of disability, i.e., time lost from school, gainful or other work, or other usual activities, in the twelve months preceding the date of the canvass. The method and scope of the survey and its broad results have been reported in earlier publications 11,12 . In the interpretation of subsequent estimates based on data of the National Health Survey, it should be noted that the survey records relating to tuberculosis, mental disease and defect, cancer, and syphilis are incomplete because of certain limitations inherent in the house‐to‐house method of enumerating illness.…”

By THEODORE D. WOOLSEY* I Actually these "onset within-no previouis attack" cases as used in this paper include three types of new cases of lesss than 7 days of consecutive disability: (1) cases in which the onset of disability was less than 7 days prior to the visit and in which the person was still disabled; (2) cases involving hospitalization, which were included regardless of the duration of disability; and (3) cases resulting in death even though death was not preceded by as long as a week of disability. 2 These proportions are for cases at all ages combined. The proportions were found to be lower for advanced ages (and also lower for the eases at younger ages which were, however, much less numerous). See figures 5, 6, and 7 in reference (9).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
