Tuberculosis (TB)

This chapter covers the key facts about tuberculosis (TB), then goes on to describe the epidemiology and pathophysiology of the disease. Risk factors, and signs and symptoms, and investigations are all covered. The treatment phase and standard drug therapies are shown, and directly observed therapy for the patient with an increased risk of poor adherence is described. Mono-resistant, multidrug-resistant, and extensively drug-resistant types are included in this chapter, as well as contact tracing in line with NICE clinical guidelines. Mycobacterium Tuberculosis (MTB) is part of a family of mycobacterium which includes Mycobacterium bovis. M. bovis is uncommon in humans, although it frequently affects cattle and badgers. MTB can affect any organ in the body; this chapter will concentrate on the diagnosis, treatment, and prevention of pulmonary MTB in adults in the UK.
