Infectious

Hello, First time posting in this forum. I am currently an undergraduate at UC Berkeley who intend to acquire MD, PhD, or MD/PhD. I've been thinking a lot lately about my post-graduation plans and I came across UC Berkeley's MPH IDV program. I would LOVE to learn more about infectious diseases and pathogenesis of bacteria, virus, parasites, and etc before I make the move to tackle more advanced degree(s). I feel that I am not quite ready to decide which path to take and that graduate courses offered through UC Berkeley's 2-year MPH program will satisfy my thirst for knowledge as well as consolidate what I want to do with my life. However, the more I research about MPH programs in general, the more I get the feeling that MPH is a professional degree with which students attempt to use it to acquire pertinent jobs, and not a mode to solely further one's knowledge. Would it be advisable to attain MPH for the purposes that I have or would it be better to find other opportunities? Thank you in advance!
