GIDEON is an impressive program. The Global Infectious Disease and Epidemiology Network was developed by Israeli and American infectious disease specialists to help physicians diagnose infectious disease cases in the context of their patients' having traveled in countries where exposure to unusual, unanticipated, or unheard of diseases would occur. Thus, diagnoses like capillariasis, Marburg virus disease, and dicroceliasis are considered along with malaria, gonorrhea, and shigellosis. The countries range from Afghanistan to Zimbabwe.
GIDEON is easy to use. Anyone familiar with the Windows format will intuitively be able to use the program without even using the manual, which itself is written in a delightfully straightforward manner. Selecting the countries traveled in, one then responds to basic questions about signs, symptoms, and laboratory values. Behind the scenes, a Bayesian analysis is progressing, and GIDEON will indicate when enough clinical information exists to establish a diagnosis. I was reminded by these prompts
