Respiratory Isolation and Restrictions to Reduce Transmission of Pulmonary Tuberculosis in Community Settings

Publication Date: April 18, 2024
Last Updated: April 22, 2024

Summary of Recommendations

Recommendation 1.1

The decision to recommend TB respiratory isolation and restriction should consider the potential benefits and harm for both the community and the PWTB. (U, U)
620

Recommendation 2.1

Respiratory isolation and restrictions in community settings should be conceptualized as a spectrum of tailored restrictions that are individualized for specific circumstances. (U, U)
620

Recommendation 3.1

Prior to effective treatment initiation, PWTB with higher respiratory bacterial burden (i.e., sputum smear and/or NAAT positivity, cavitation on chest imaging) may be considered as relatively more infectious than those with lower bacterial burden, with individual variability. (S, M )
620

Recommendation 3.2

PWTB on less than five days of effective treatment should be considered relatively more infectious than those on longer durations of effective therapy. (S, M )
620

Recommendation 3.3

PWTB on effective treatment for at least five days should be considered non-infectious or low likelihood of infectiousness, regardless of sputum bacteriologic status during treatment (i.e., smear-microscopy, NAAT or culture status), with certain exceptions. (C, M )
620

Recommendation 3.4

Overall risk of transmission to others should consider both a PWTB’s infectiousness, as well as other factors including the environment of potential exposures, proximity, frequency, and durations of exposure, and biological susceptibility of contacts. (U, U)
620

Recommendation 4.1

RIR is not recommended for persons with non-infectious forms of TB (i.e., localized extrapulmonary TB without pulmonary involvement, as confirmed by sputum bacteriologic studies and/ or chest imaging). (U, U)
620

Recommendation 4.2

People with pulmonary TB on effective treatment and low likelihood of infectiousness should not have restrictions in most circumstances (i.e., RIR should be removed, if present), with individual exceptions for situations involving higher risk community settings and populations (e.g., children < 5, immunosuppressed individuals). (C, M )
620

Recommendation 4.3

Community-based RIR may be considered for PWTB that have higher infectious potential in which there is judged to be higher risk of transmission to the community. (C, L )
620

Recommendation 5.1

When considering restrictions for PWTB, a moderate or midlevel range of RIR should be considered appropriate in most circumstances, with individual exceptions. (U, U)
620

Recommendation 5.2

Specific RIR levels (e.g., low, moderate, or extensive) and duration for PWTB should be reassessed routinely (at least weekly) and may be modified based on individual considerations or changing circumstances. (U, U)
620

Recommendation 5.3

When RIR is implemented, support should be provided to patients to mitigate anticipated and experienced harms. (U, U)
