A tuberculose
continua sendo mundialmente um importante problema de saúde, exigindo o
desenvolvimento de estratégias para o seu controle.

O Brasil é um dos 22 países priorizados pela OMS que
concentram 80% da carga mundial de TB.

É importante destacar que
anualmente ainda morrem 4,5 mil pessoas por tuberculose, doença curável e evitável.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Diagnosticar
e tratar correta e prontamente os casos de TB pulmonar são as principais
medidas para o controle da doença. Esforços devem ser realizados no sentido de
encontrar precocemente o paciente e oferecer o tratamento adequado,
interrompendo a cadeia de transmissão da doença.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; A tuberculose é transmitida por via
aérea em praticamente todos os casos. A infecção ocorre a partir da inalação de
núcleos secos de partículas contendo bacilos expelidos pela&nbsp; tosse, fala ou espirro do doente com
tuberculose ativa de vias respiratórias ( pulmonar ou laríngea) os doentes
bacilíferos, isto é, aqueles cuja baciloscopia de escarro é positiva são a &nbsp;principal fonte de infecção.

&nbsp;&nbsp;&nbsp;&nbsp;
Doentes de tuberculose pulmonar com baciloscopia negativa, mesmo que
tenham resultado positivo á cultura, são muito menos eficientes como fontes de
transmissão, embora isso possa ocorrer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; As formas exclusivamente extra pulmonares
não transmitem a doença.
