Can TB be contracted in any unconventional way apart from air ?

Answer 1

Breast feeding, if the mother hasn't been treated and is contagious.

You don't get TB by just touching the clothes or shaking the hands of someone who is infected. Tuberculosis is spread (transmitted) primarily from person to person during close contact by breathing infected air.

There is a form of tuberculosis, however, that is transmitted by drinking unpasteurized milk. Related bacteria, called Mycobacterium bovis, cause this form of TB. It previously was a major cause of TB in children, but rarely causes TB now since most milk is pasteurized (a heating process that kills thebacteria).
