Miliary tuberculosis causes

Disseminated TB develops in the small number of infected people whose immune systems do not successfully contain the primary infection. It can occur within weeks of the primary infection. Sometimes, it does not occur until years after you become infected. Chances of having miliary tuberculosis is high if the immune system is weakened due to disease (such as AIDS) or certain medications. Infants and the elderly are also at higher risk.
