Question 1

Which hand hygiene method is most effective at eliminating bacterial spores such as Clostridioides difficile?

Soap and water handwashing

Answer

Alcohol-based products do not kill C. difficile spores; soap and water mechanically removes them through friction and rinsing.

Standard Precautions apply to blood and all body fluids (except sweat), non-intact skin, and mucous membranes for all patients regardless of diagnosis.
