Hi, you might have had latent tuberculosis infection. Latent tuberculosis infection (LTBI) is a condition in which a person is infected with. M. tuberculosis, but does not currently have active tuberculosis disease.  The primary infection is usually asymptomatic (majority of cases), although a small number go on to have symptomatic haematological dissemination which may result in miliary tuberculosis. Only in 5% of patients, usually those with impaired immunity, go on to have progressive primary tuberculosis.
