(NHSchoices, 2010)  In addition, lymph nodesnear the heart and lungs become enlarged.

(NHS inform, 2015) General symptoms of TB may include lack ofappetite, weight lose and high temperature. An individual may also experiencenight sweats and extreme tiredness or fatigue. (NHS Choices, 2015) Mostinfections affect the lungs, which can cause persistent cough that lasts more than threeweeks and usually brings up phlegm, which may be bloodybreathlessness that gradually gets worse.

(NHSchoices, 2015)Causes: Tuberculosisis caused by an organism called Mycobacterium tuberculosis. (NHS choices.2015) The bacterium spreads from person to person through microscopic dropletsreleased into the air. This can happen when someone with the untreated, activeform of tuberculosis coughs, speaks, sneezes, spits, laughs or sings.

Therefore,it is important for healthcare providers to have their face masks and gloves on,when nursing a person with TB, so that they do not catch the infection. Mostpeople with active TB who have had appropriate drug treatment for at least twoweeks are no longer contagious. (NHS choices, 2015)
