**Clostridium difficile is a spore-forming organism that can be
transmitted through direct and indirect patient contact. Because
Clostridium difficile is a spore-forming organism, hand sanitizer is
not effective in preventing its transmission. Hands must be washed
with soap and water to prevent transmission. This organism is not
transmitted via the droplet route; therefore Droplet Precautions are
not needed. An N95 respirator is used primarily for patients with
airborne illness. All patients should be taught cough etiquette; this
action is not one to be take especially because the patient has
Clostridium difficile.**
