Standard Precautions 1 Hand Hygiene. In one of these outbreaks, preparation of medications in the same workspace where used needle/syringes were dismantled also may have been a contributing factor. When a single-patient room is not available, consultation with infection control personnel is recommended to assess the various risks associated with other patient placement options (e.g., cohorting, keeping the patient with an existing roommate). The first reason is to protect patients. Standard Precautions are also intended to protect patients by ensuring that healthcare personnel do not carry infectious agents to patients on their hands or via equipment used during patient care. The transmission of SARS-CoV in emergency departments by patients and their family members during the widespread SARS outbreaks in 2003 highlighted the need for vigilance and prompt implementation of infection control measures at the first point of encounter within a healthcare setting (e.g., reception and triage areas in emergency departments, outpatient clinics, and physician offices).21, 254, 897 The strategy proposed has been termed Respiratory Hygiene/Cough Etiquette 9, 828 and is intended to be incorporated into infection control practices as a new component of Standard Precautions.

MRSA is the only MDRO for which effective decolonization regimens are available.867 However, carriers of MRSA who have negative nasal cultures after a course of systemic or topical therapy may resume shedding MRSA in the weeks that follow therapy.934, 935 Although early guidelines for VRE suggested discontinuation of Contact Precautions after three stool cultures obtained at weekly intervals proved negative, 740 subsequent experiences have indicated that such screening may fail to detect colonization that can persist for >1 year.27, 936-938 Likewise, available data indicate that colonization with VRE, MRSA, 939 and possibly MDR-GNB, can persist for many months, especially in the presence of severe underlying disease, invasive devices, and recurrent courses of antimicrobial agents. Alternatively, an interval free of hospitalizations, antimicrobial therapy, and invasive devices (e.g., 6 or 12 months) before reculturing patients to document clearance of carriage may be used.

According to the World Health Organization, Airborne transmission of infectious agents refers to the transmission of disease caused by the dissemination of droplet nuclei that remain infectious when suspended in air over long distance and time. Airborne transmission can be characterized as obligate or preferential depending on whether it is only transmitted via droplet nuclei or if it has multiple other routes of transmission.
