We thank Drs. Brody and Potterat for their letter (1) on our study (2). In response to the concerns they expressed, we wish to clarify the definition of two terms that are widely understood in the public health community but may pose a challenge to researchers in academic settings." Validity" refers to the accuracy of a measurement not due to chance (3)." Surveillance" refers to population-based information that is collected, analyzed, and disseminated for public health action (4).To evaluate the validity of surveillance systems in contrast to die validity of clinical research studies, chart reviews are usually conducted (4). Although a" gold standard" source of information on human immunodeficiency virus (HTV) risk has not been determined, in our study (2) we considered medical charts to be the most accurate source among the sources accessible to health departments. Physicians conduct individual assessments of patients' medical and social histories; we should not assume that the confidential information a patient shares with his or her medical care provider is untrue. Drug use has legal implications; however, self-reported information on drug use is considered valid (5).
