Re-evaluation is sometimes carried out, to eliminate false-negative results (Ignativicius & Workman, 2010; p.669).
Chest X-rays are also another method of diagnosis to ascertain a suspected tuberculosis infection. The tubercle lesions formed by the mycobacteria on initial infection are specifically examined and although not a conclusive diagnostic technique, it further confirms other diagnostic methods (Battle, 2009; p.313). Other respiratory diseases have similar images as those presented by tuberculosis; hence the reason for not taking chest x-rays alone as conclusive diagnosis for tuberculosis (Battle, 2009; p.313).

Since tuberculosis is an airborne infection, transmission of infection is highest in areas of overcrowding and poor ventilation. Thus an improvement in the living conditions will have a ripple effect and reduce transmission of infection among people. Early detection and treatment is a major method of control and prevention of tuberculosis (Battle, 2009). This is the main focus of tuberculosis programs- primary and secondary prevention strategies (Walley & Wright, 2010; p.267). This early commencement of treatment, curtails the possible spread of the organism and multiple
