transmission-based precautions remain in effect for limited periods of time (i.e., while the risk for transmission of the infectious agent persists or for the duration of the illness (appendix a). 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. for some diseases (e.g., pharyngeal or cutaneous diphtheria, rsv), transmission-based precautions remain in effect until culture or antigen-detection test results document eradication of the pathogen and, for rsv, symptomatic disease is resolved. for other diseases, (e.g., "m. tuberculosis") state laws and regulations, and healthcare facility policies, may dictate the duration of precautions 12). in immunocompromised patients, viral shedding can persist for prolonged periods of time (many weeks to months) and transmission to others may occur during that time; therefore, the duration of contact and/or droplet precautions may be prolonged for many weeks. the duration of contact precautions for patients who are colonized or infected with mdros remains undefined. mrsa is the only mdro for which effective decolonization regimens are available. 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. although early guidelines for vre suggested discontinuation of contact precautions after three stool cultures obtained at weekly intervals proved negative, subsequent experiences have indicated that such screening may fail to detect colonization that can persist for 1 year. likewise, available data indicate that colonization with vre, mrsa, 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. it may be prudent to assume that mdro carriers are colonized permanently and manage them accordingly. 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. determination of the best strategy awaits the results of additional studies. see the 2006 hicpac/cdc mdro guideline for discussion of possible criteria to discontinue contact precautions for patients colonized or infected with mdros.
