Good afternoon doctors. I have a concern about my health. I m still 20 years old, female. I have been X-ray last July 2013, the findings were Fibroid infiltrates left upper lobe. Do I have TB already? but how? Am I infectious? I didn t heard some of my friends they were infected were in fact we ve been sharing foods a lot. I was undergone treatment for six months. After that, I have X-ray again just today to see if there is improvement and while reading again the result, I was so sad. The findings were, Fine streaky and nodular densities are seen at the left first anterior intercostal space. Rule out Koch s Infection. How come I still have this infection in my result? Were in the first place I ve done already my treatment. Am I contagious? Please help me.
