Welcome back to episode 15! As promised, we are back to our weekly episodes leading into the ITE. We start this week with a rapid review of some of the infectious disease high-yield points that we have covered in the past few months, and then we dive right into the new material. Stay tuned for some comical outtakes at the end of the podcast for an inside look at the recording of Roshcast. We think you will enjoy it. Let’s get on with the rapid review.
