ISID’s STEP Program is a short term (range 2 to 4 months) clinical infectious diseases trainee exchange program to enable Infectious Diseases fellows to get training in select academic programs outside of their own and to transfer that expertise to their home institution. The pilot program will support fellows to rotate to a Training Program within their region. South America was selected for the pilot to coincide with the 18^th International Congress on Infectious Diseases that will be held in Argentina in March 2018.
