Resumen

The TB recurrence occurs when a patient presents current diagnosis of tuberculosis with positive bacteriology ( microscopy or culture) , with history of cured TB with anti -TB drugs. Evaluation of the clinical and epidemiological aspects of TB recurrence is extremely important, because this data is able to guide and clarify the effectiveness of DOTS ( Directly Observed Treatment Short), the pharmacological treatment regimen used and the predisposing factors for recurrence. Objective: Describe some characteristics of clinical and epidemiological profile of tuberculosis recurrence in Jundiaí in the period 2006-2011. Methods: This is a descriptive study, type of survey data from the Officer of the Ministry of health of Brazil named Tbweb.
