Sterilizing Computer Surfaces

Sterilizing Computer Surfaces

I have an acquaintance who works at a school where there was a suspected case of swine flu and they had to sterilize all the surfaces in the school, including the computers in the computer lab. What would sterilize a computer in such a situation without damaging it? Would simple alcohol wipes suffice? These would be standard desktop machines with a mix of CRT and LCD monitors.
