Which personal hygiene practice is ineffective when dealing with certain infections like C-Diff?

When addressing infections such as Clostridium difficile (C-Diff), using hand sanitizer is ineffective because these types of infections are spore-forming bacteria. Hand sanitizers, while effective against many germs, do not eliminate C-Diff spores, which can survive on surfaces and hands. The most effective method for preventing the spread of C-Diff is thorough handwashing with soap and water, as this physically removes the spores from the skin rather than just reducing their numbers.

Using gloves is important to prevent the spread of infection when caring for someone infected with C-Diff, and dressing wounds properly helps to protect against infection. Therefore, it's crucial to understand the limitations of hand sanitizers in the context of certain resistant infections like C-Diff and the importance of proper hand hygiene.
