Tuberculosis is an infection caused by Mycobacterium tuberculosis. It most commonly affects the lungs. Tuberculosis is one of the most deadly and common major infectious diseases today. TB infection begins when MTB bacilli reach the pulmonary alveoli, infecting alveolar macrophages, where the mycobacteria replicate exponentially. When it has increased to such an extent that it needs to more space…it is going to find ways to spread. TB is spread by aerosol droplets expelled by people with active TB disease of the lungs when they cough, sneeze, speak, or spit. Each droplet is 5 micrometre|µm in diameter and contains 1 to 3 bacilli ---RATIONALE FOR COUGH. TB infections get contained to certain areas by the granuloma formation….Granulomas can have caseous necrosis in the centre. Sometimes they may break open during a coughing bought and lead to coughing up blood hemoptysis. –RATIONALE FOR HEMAPTYSIS CHILLS –are due to our immune system response to the diseases. It is a cycle of FEVER – CHILLS – NIGHT SWEATS. RATIONALE FOR CHILLS – IMMUNE RESPONSE?? MILD FEVER – because the body doesn’t recognize the danger of this bacteria as macrophages would have already phagocytosed them and contained them in a granuloma…The body knows that there is a fever…but thinks it has contained it.. RATIONALE FOR MILD FEVER
