Representativeness: Percentage of AIDS cases reported using the Form 506/1 was 58.7% (88/150) (Figure 2). The officers lacked motivation for reporting AIDS cases as most of them were aware that consequences of failing to provide AIDS reports were less severe than that of failing to provide other kinds of reports. One officer said, “Sometimes I think ‘why do I need to make a report?’ because some officials do not report but nothing happens. We don't use anything from the report. Report or don’t report, no one knows”. Moreover, the officers changed very frequently, leading to lack of continuity in the work.
