    Thank you. How do I tell the difference between primary and secondary infection in a vignette, if they dont give the location of the lesion in the lung? I only knew child for primary and adult for secondary, but I had one question where there was an adult and i had to choose the answer for primary. Also why does Secondary TB affect the upper lobe and not the bottom? I heard two reasons, which is correct? One is that the upper lobe has higher V/Q so more vent RELATIVE to perfusion, and the other reason was that the TB is trying to run away from the now developed immune system by going to the area of least perfusion, and doesnt care about ventilation by this point(otherwise it wudve gone to the bottom)
