*Mycobacterium tuberculosis, *Mycobacterium africanum, *Mycobacterium bovis, *Mycobacterium tuberculosis complex
| Practice / Additional Precautions: ROUTINE : Skin test positive with no evidence of current disease |
Mode of Transmission: |
| AIRBORNE : +Pulmonary – confirmed or suspected or laryngeal disease |
Airborne |
| AIRBORNE : +Extra-pulmonary, draining lesions | Airborne
during aerosol generating procedures |
| ROUTINE : Extra-pulmonary, no draining lesions |
|
| Infectious Material: Aerosolized respiratory droplet nuclei Aerosolized droplets generated during irrigation/manipulation of cutaneous tuberculous lesions |
Duration of Additional Precautions: Suspected pulmonary: Continue precautions until TB ruled out. Confirmed pulmonary: Until 2 weeks of effective therapy, patient improving, and 3 consecutive sputum smears negative for AFB collected 24 hrs. apart. If multidrug-resistant TB, continue until culture negative. Extra-pulmonary draining lesions: Continue precautions until drainage ceased or until 3 consecutive AFB smears. |
| Signs & Symptoms: Weight loss, fever, night sweats, pulmonary pain, cough, bloody expectoration, lesion on diagnostic imaging |
|
| Comments: +For pulmonary and extra-pulmonary draining lesions single room, negative air flow and door closed. +Fit-tested and seal-checked N95 respiratory required for pulmonary disease, extra-pulmonary draining lesions and aerosol generating procedures. For extra-pulmonary (no draining lesions) i.e. meningitis, bone and joint infection and PPD (purified protein derivative) reactive test with no evidence of current pulmonary disease, use Routine Practices * Reportable Disease except skin test positive with no evidence of current disease |
