Bedsite tables, bed rails, dry or wet surfaces and even gloves and healthcare workers’ apparels are reservoirs for or sources of infectious agents.
Some environmental conditions contribute in the proliferation of microorganisms: Ventilation, number of people per room, intensity of the activity, humidity level, among others.
Finally, the primary route of transmission is contact.

Hospital cleaning and disinfection are systematic procedures that collaborate with infection control, whose effectiveness depends on:

Clear rules and fluent communication.
Procedures adequate for each area.
Staff trained in the task and importance of cleaning to fight against hospital infections.
Staff aware of the role played by cleaning in the protection of hospitalized patients.
Cleaning procedures monitored with the aim of validating their efficiency or correcting their performance.
