To the Editor.—
The article entitled "Underreporting of AIDS Cases in South Carolina, 1986 and 1987"1 was noteworthy in its findings that only 59.5% of reportable cases of acquired immunodeficiency syndrome were actually reported. In September 1987, the Centers for Disease Control revised the definition of acquired immunodeficiency syndrome, adding 31 chronic diseases and 10 lymphomas to the then-existing list of criteria.2-4Is it possible that such a discrepancy in reporting, as described in this article, was due primarily to the change in definition (criteria for reporting) of acquired immunodeficiency syndrome that occurred after the data in question were collected, tabulated, and published?
