Iv'e read several places about how long the N virus lives for. 12 hours on soft surfaces, 24 on hard ones etc...

My question is, if I were to touch a door handle where the virus had been for 20 hours, then touch something uncontaminated, will the virus then live on the new surface for another 12-24 hours, or will it only survive for the remaining hours of its lifetime since leaving the body?
