The environment can contribute to a person’s susceptibility to tuberculosis, with a number of factors increasing
the risk of developing active disease. In this chapter, we shall examine the evidence for an association between TB and
nutrition, smoking, alcohol, intestinal parasite infection, and the newer anti-TNF immunosuppressive drugs. For further in
depth information, readers are guided towards reviews on individual topics where available. Concurrent disease, other
immunosuppressive medication and HIV infection have been covered elsewhere.
Keywords: Alcohol, anti-tumour necrosis factor, nutrition, parasitic infection, smoking, tuberculosis.
