“More bugs, more drugs!“More bugs, more drugs!
QuestionQuestion: When does tuberculosis : When does tuberculosis infection turn into tuberculosis infection turn into tuberculosis disease? When do we cross the disease? When do we cross the threshold or using more than one threshold or using more than one threshold or using more than one threshold or using more than one drug?drug?
