"Bleach" wipes don't actually contain bleach. That's a common misperception that people have, because those wipes are made by the bleach company. I'm not sure how effective they are against bacteria and viruses.
Also, bleach won't kill everything. Cryptosporidium, a cause of diarrhea, is not killed by bleach and must be killed with hydrogen peroxide.
I would say, though, go ahead and bring the gifts, but include one of those hand sanitizers. (Keep in mind that alcohol doesn't kill everything, either!)
You have to really pay attention to the labels on the bleach wipes. It has to say “with bleach.” Same for a lot of the ‘spray cleansers.’
Make your own bleach wipes. Use a half roll of heavy duty paper towels. Boil 10 parts water and add 1 part bleach. Place half roll of paper towels in an old wipes container or any container with a lid they fit into. Pour your mixture over the paper towels. Remove cardboard inner tube. Use roll from the inside out.
washing with soap and water is the recommendation for preventing the spreading C-diff......not alcohol or bleach, etc...
