Tuberculosis is primarily spread through which activity?

• A. Sneezing or talking
• B. Eating contaminated food
• C. Sharing utensils
• D. Skin-to-skin contact

Answer: (A)

Tuberculosis spreads mainly through the air when someone with active pulmonary TB coughs, sneezes, or talks, releasing tiny droplet nuclei that can linger in the air and be inhaled by others. That’s why sneezing or talking is the best answer: these activities aerosolize the bacteria, enabling transmission in close or poorly ventilated spaces. It isn’t spread by eating contaminated food, sharing utensils, or skin-to-skin contact, which involve different, non-airborne routes.
