<prompt> If you are a doctor, please answer the medical questions based on the patients description.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?  <response>: 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 dont 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 dont desperate, if you have any symptoms of tuberculosis, consult a physician and get his opinion. If dont 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.
