USB ESD protection

I am using a microcontroller (PIC32) with a USB interface. The USB interface will be often exposed to human body ESD discharges. Should I protect against these, and if so, how?

I have found this to be a good article that explains ESD protection: System-Level ESD/EMI Protection Guide
