I'd doubt that any significant amount of fires are caused by loss of isolation between line and output side. While it might be very unpleasant to touch any device that came into contact with the live wires, there's not really much current you can have flowing. And if any significant current flows, a GFI should catch this, and shut down the power. Regarding the amont of deaths by electrocution: How much people are actually electrocuted by badly designed house appliances? As far as I see there's only very little injury related to electrical shock outside of actual electrical or construction work, where people might naturally be more easily exposed to live wiring carrying higher currents, possibly higher voltages and, most importantly much lighter standards in terms of circuit breakers.
