Tuberculosis

Progression from TB infection to overt TB disease occurs when the bacilli overcome the immune system defenses and begin to multiply. In primary TB disease (some 1–5% of cases), this occurs soon after the initial infection. However, in the majority of cases, a latent infection occurs with no obvious symptoms. These dormant bacilli produce active tuberculosis in 5–10% of these latent cases, often many years after infection.

    “With sighs more lunar than bronchial,
    Howbeit eluding fallopian diagnosis,
    She simpers into the tribal library and reads
    That Keats died of tuberculosis . . .”
