The need for timely collection and analysis of epidemiological data is becoming of primary importance, e.g., for bioterrorism detection or epidemiological surveillance. Web-based information systems (WISs) may provide the needed technological support. Thus we present the WeeW (workflow-enabled epidemiological WIS) system—i.e., a WIS that helps epidemiologists, through workflow management, to effectively select remote centers, collect, and process the received data to produce conclusive technical reports. In detail, we show the functionalities of the WeeW system, its architecture, and particularly Stata’s role in executing statistical analyses and producing graphs. Furthermore, we discuss the performance of the WeeW–Stata interface. Finally, we outline short conclusions regarding the advantages and drawbacks connected with the proposed solution.
