See below: You are referring to latent TB becoming TB pulmonary infection. After primary TB infection the organism becomes latent within granulomata in the body. In 10% of infected persons (5% within 2 years of primary infection) this latent TB reactivates and causes active infection most commonly in the lungs but also in lymph nodes, cns, kidneys, peritoneum, bone etc. Aging and immunosuppression preceed.
