Hi, I Am Recentky Confined In The Hospital. We Found

Hi, i am recentky confined in the hospital. We found the xray result last 2011 w/ the findings pulmonary calcifixation. Only then, this week it has realized that i have tuberculosis from the results of the citi scan and skin test. But i haven't experience fever and only once in a year i get cough but no fever and no blood secreted. Is my case considered latent tuberculosis? If it is latent, is there an assurancd that i cannot transmit the disease to the people i spend w/ everyday. Thank yiu doc.
