Prognosis
Without treatment the mortality rate of TB exceeds 50%; however, TB is a treatable disease. In the US in 2009 there were 529 deaths because of TB out of 11,528 reported cases, a case fatality rate of 4.6%. Risk factors for death include increased age, delay in diagnosis of TB, extent of radiographic involvement, the need for mechanical ventilation, end-stage renal disease, diabetes, and immunosuppression.[108][109]
In general, patients with treated TB can expect to do well with minimal or no sequelae.
