This bacillus is released by the exercise of speech or other event that Externalise saliva (coughing or sneezing) enhances the patient with TB respiratory airways, is lung or larynx. Tuberculosis is considered a major public health problem worldwide.

Faced with this data, Brazil is among the twenty-two countries that concentrate a majority of TB cases, with approximately 82% of cases. It can be said that tuberculosis is a "scandal" since despite having so many ways to cure it can not spread it. With this is evident negligence, ignorance of tuberculosis problems, weaknesses of institutions, but the foremost of all is the lack of cooperation on the part of patients because most end up abandoning the treatment.
