Tuberculosis is Transmitted Primarily Through

Question

Tuberculosis is transmitted primarily through
A)aerosols.
B)fomites.
C)blood transfusions.
D)oral-fecal route.

Accepted Answer

Tuberculosis is primarily transmitted through aerosols, which are produced when a person with an active TB infection coughs, sneezes, speaks or sings. These aerosols contain Mycobacterium tuberculosis, the bacterium that causes TB, and they can be inhaled by others who are near the infected person. Fomites, blood transfusions, and the oral-fecal route are not primary modes of transmission for TB.
