C
Feedback:
Hand hygiene remains the single most important measure to prevent the spread of infection. It reduces the number of transient and resident microorganisms. Sufficient food intake helps restore biologic defense mechanisms but does not prevent spread of infections. Although minimal social contact and regular immunizations may help prevent the spread of infection, especially community-acquired infections, these are not practical measures.
