Question

M tuberculosis may be transmitted from an infected person by

		sharing food or drink
		coughing and shouting
		sharing a toothbrush
		kissing

Answer 1

The answer is ----- Coughing and shouting.

Explanation :

Mycobacterium tuberculosis is a pathogenic bacteria that causes tuberculosis. It is spread via air. When a person with active tuberculosis coughs or sneezes, the bacteria is transmitted to air and when the other person inhales the air and depending upon the immune reaction, the person develops tuberculosis. Therefore, it is spread via coughing, shouting, sneezing that dispers the pathogenic bacteria into air and not via sharing food or drink, sharing a toothbrush, kissing or via touching or changing of bedlinens. Therefore, all the other options are incorrect and coughing , shouting is the correct option.
