In this study, the main focus was the epidemiology of gonorrhea, which is characterized by geographically defined hyperendemic areas, or “cores.” The authors of the study developed a GIS system linked to the disease surveillance database at the Baltimore Health Department and used this system to evaluate the geographic epidemiology of gonorrhea in Baltimore, Maryland. There were 7,330 reported cases, of which 87.4% were in persons aged 15–39 years; 56.6% were of the cases were in males; and 60.5% of the cases were reported from the nonsexually transmitted disease (STD) clinic sector. The mapping of cases by provider showed that cases reported from STD clinics had similar geographic distribution to those from the non-STD clinic sector. From an operational perspective, GIS technology offered new opportunities to evaluate these patterns. GIS effectively integrated with clinical data systems to provide epidemiologic analysis.
