In 2012, a “Drug Link” was added to the profile page of many of  the infectious diseases in IDdx. The Drug Link is a hyperlink to the pertinent page on The Merck Manual and CDC websites. According to the Merck website, “The web publications are continuously updated to ensure that the information is as up-to-date as possible.” IDdx also has a field called “Treatment” that has some brief information for some of the infectious diseases.
