[|Human|] i had active t.b. at age 19 yrs and went thru sugery and a wedge from upper left lung was removed, i am now age 66 and have been exposed to a person with active t.b. what are my chances of getting this again f this being active again?
[|AI|]  Hellhole me explain that so many patients come in the tuberculosis hospital and doctor & paramedics treat them. Mostly or few of them may have active (infectious) or contagious disease but they don't suffer. Similarly, you operated way back 47 years for tubercular lesion in lung. Now at the age of 66 years you came in contact a patient having active tuberculosis. How your chances of getting infection? I want to tell you that tubercular bacilli (mycobacteria) are airborne Chat Doctor.  So in air and in sputum (of patient) they may present. In your case you may have inhaled some bacteria (not disease) but your defense system (immune system) can kill all bacteria. In my opinion don't desperate, if you have any symptoms of tuberculosis, consult a physician and get his opinion. If don't have any symptoms no need of any fear and enjoy life. Fever, cough, hemoptysis (blood in sputum) , weight loss, fatigue, breathlessness are few symptoms of tuberculosis. Good luck.
