Dear StataList-ers!

I have the following dataset, focused on sexually-transmitted disease in USA (state level) by year and gender. Instead of a single variable "Disease", I would like to deal with the numerous types of disease as separate variables (e.g. "Gonorrhea rate"; "Primary Syphilis rate", "Total Syphilis rate", etc.). I read the help files for reshape and collapse, and watched some tutorials. This seems like a very basic question but I am still not sure how to manage this Please, help!
