Tuberculosis is transmitted through

Tuberculosis is transmitted through

• A. Coughing and sneezing by an infected person
• B. Contaminated food
• C. Skin-to-skin contact
• D. Blood transfusion

Answer: (A)

Tuberculosis spreads through airborne droplets released when an infected person coughs, sneezes, talks, or sings. These tiny particles can linger in the air and be inhaled by others, especially in close or poorly ventilated spaces, so the act of coughing or sneezing by an infected person is the mechanism that commonly transmits TB. It’s not spread by contaminated food, skin-to-skin contact, or blood transfusion, which is why those options aren’t the correct route of transmission.
