Consider the following statements: 1. Tuberculosis (TB) is caused by the bacterium Mycobacterium tuberculosis. 2. It is primarily spread in humans through inhalation of airborne droplet nuclei. Which of the above statement(s) is/are correct?

Explanation

Both statements are correct with the transmission route stated precisely. Mycobacterium tuberculosis causes TB, and infectious people can release tiny airborne particles containing the bacteria. These droplet nuclei may remain suspended and be inhaled; this is airborne transmission rather than surface contact or ordinary large-droplet spread.
