if a mummy slams me i have to save vs mummy rot, but what if I unarmed attack it and make a hit. do I need to save then too? would gloves be a safe alternative? what if I wore a robe and burnoose? maybe why they are popular in the desert.
A mummy touching you and you touching it are two completely different things in Pathfinder. Mummy Rot specifically states it is delivered by the Mummy's slam attack, so nothing else risks infection. You could even bite the thing without getting the Rot.
