To this end, infection control departments have been established in hospitals. These departments implement specialized programs aimed at preventing or halting the spread of infection among patients and all hospital staff. This is achieved through the implementation of a set of policies, guidelines, and preventive measures. For example, standard procedures based on risk assessments are used, along with personal protective equipment and methods, to protect healthcare providers from infection and prevent the spread of infection from patient to patient. Furthermore, various methods and approaches are employed to ensure a clean, infection-free environment.
