Use of protective barriers (Personal Protective Equipment (PPE)). 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. Airborne transmission occurs through the dissemination of either: Microorganisms carried by the airborne route can be widely dispersed by air currents and may become inhaled by a susceptible host in the same room or over a long distance form the source patient depending on environmental factors such as temperature and ventilation. A special note to be made is regarding COVID-19, the 21st-century pandemic which is thought to spread through airborne routes (among other routes). %PDF-1.7 Last updated on Feb 6, 2023.

The germs can remain in air or dust for a long time and spread far from you to others. For other diseases, (e.g., M. tuberculosis) state laws and regulations, and healthcare facility policies, may dictate the duration of precautions12). For most infectious diseases, this duration reflects known patterns of persistence and shedding of infectious agents associated with the natural history of the infectious process and its treatment. It may be prudent to assume that MDRO carriers are colonized permanently and manage them accordingly. They help stop germs from spreading so other people don't get sick. An AIIR is a single-patient room that is equipped with special air handling and ventilation capacity that meet the American Institute of Architects/Facility Guidelines Institute (AIA/FGI) standards for AIIRs (i.e., monitored negative pressure relative to the surrounding area, 12 air exchanges per hour for new construction and renovation and 6 air exchanges per hour for existing facilities, air exhausted directly to the outside or recirculated through HEPA filtration before return).12, 13 Some states require the availability of such rooms in hospitals, emergency departments, and nursing homes that care for patients with M. tuberculosis.

The strategy is targeted at patients and accompanying family members and friends with undiagnosed transmissible respiratory infections, and applies to any person with signs of illness including cough, congestion, rhinorrhea, or increased production of respiratory secretions when entering a healthcare facility.40, 41, 43 The term cough etiquette is derived from recommended source control measures for M. tuberculosis.12, 126, The elements of Respiratory Hygiene/Cough Etiquette include, Covering sneezes and coughs and placing masks on coughing patients are proven means of source containment that prevent infected persons from dispersing respiratory secretions into the air.107, 145, 898, 899 Masking may be difficult in some settings, (e.g., pediatrics, in which case, the emphasis by necessity may be on cough etiquette.900 Physical proximity of <3 feet has been associated with an increased risk for transmission of infections via the droplet route (e.g., N. meningitidis 103 and group A streptococcus 114 and therefore supports the practice of distancing infected persons from others who are not infected.
