The NIH announced that a newly released software program will help analyze data at the site of infectious disease outbreak. This tool, called TranStat, will speed the detection of new cases and help imlement effective interventions. Its developers, a team of epidemiologist and computer scientists from the Models of Infectious Disease Agent Study (MIDAS), created the software in order to make the models developed by researchers available to the public health community.
You can download the program for free at http://www.midasmodels.org, where you can enter and store infectious disease data (like age, sex of infected individuals and onset of symptoms, close contacts, etc). The program uses this info to statistically determine the probability that people contracte the disease from each other, the average number of people an individual could infect, and the rate that the infection occurs.
