A system to evaluate the presence of a diarrheal epidemic caused by Shigella and Salmonella

Epidemic modeling of a disease like diarrhea help in understanding the dynamics of the disease as well as preventing it. According to the pathogenesis, models for Shigella and Salmonella have been formulated and the basic reproduction number (R
₀
) has been evaluated. These models have been built up into a user-friendly graphical user interface that displays the presence and effects of the epidemic. It was established that as long as R
₀
<;1, there will be no epidemic. The outputs from the system are very clear and help in determining the extent and existence of the epidemic.
