The implication of the airborne theory of tuberculosis is radical, namely, that infection can only occur under special conditions. This accounts for some of the peculiar epidemiological aspects of tuberculosis and explains the observation that some individuals may be exposed to an open case for several months without becoming tuberculin positive.
