HIV/AIDS barely survives the environs outside the human body. A disease passed through blood and semen, HIV poses little to no risk in the casual setting. In fact it really won't survive outside a host. So door knobs, utensils, etc., pose little risk. A weak bleach solution used for disinfection will easily clean any HIV organisms away.
As an aside, one of the fastest growing group of HIV positive people are something like 12-21 year old caucasion americans.
