Explanation

While on TB treatment, especially during the contagious initial phase, patients should wear a surgical mask when around others to prevent airborne dispersal of Mycobacterium tuberculosis. Prophylactic antibiotics for family members should only be considered under medical advice after assessment. The use of separate utensils and bedding is not necessary for TB, as it is spread through the air and not by surface contact. Limiting outdoor activities does not prevent the transmission to cohabitating family members. The key to preventing spread within a household is reducing exposure to infectious droplets.
