What level of protection do sheets and other linens on the mattress provide to germ-transmission?

The CDC recognizes that bed sheets do not protect mattresses from becoming contaminated with body fluids and substances.25 This means that any body fluids or pathogens from the patient can directly contact the mattress and vice versa. This puts patients at serious risk and emphasizes the importance of providing patients with a completely clean mattress and the need to perform high-level disinfection.23
