___________________________________.Dr. Shanks explained why it's spread so quickly and so far.Shanks医生还解释了为什么到目前为止它会传播得如此之快。"We know that drug resistance is a man-made problem. It comes from incorrect treatment. It comes from the availability of over-the-counter tuberculosis medications. It comes from patients not taking their drugs properly or drug supplies running out. So they're not able to finish their treatment. And sometimes it comes from just doctors' prescribing patterns," “我们知道耐药性是人为因素导致的问题。这些因素包括：不正确的治疗方式，不经医生处方即可获得的结核病药物，病人因用药不当或缺少药物而导致无法完成治疗。有时，只是医生开处方的模式也会导致耐药性。”
