A school-age child is admitted in acute respiratory failure requiring mechanical ventilation.

An acid-fast bacillus (AFB) is strongly associated withMycobacterium tuberculosis (TB). TB is ahighly contagious airborne disease, and infection control standards require immediate placement in anegative-pressure roomto prevent spread to other patients and healthcare workers.

“Suspected or confirmed pulmonary tuberculosis in a mechanically ventilated patient necessitates immediate airborne isolation using a negative-pressure room. Infection control must be prioritized prior to confirmation of diagnosis.”
