Select the ways patients and their visitors and caregivers can help break the chain of infection in healthcare facilities.

Patients and visitors can help prevent infection by learning about risks related to the patient’s treatment and by speaking up if healthcare professionals have not cleaned their hands.

Avoiding all hospital visits throughout the entire cold and flu season is not a practical infection-prevention measure, so D is not correct.
