No, you do not have to take any medicine. Almost all chinese are TB positive, which indicates that there is TB antibody in our blood. This is simply because we were immunized with BCG vaccine in China. However, in such case, American doctors usually think we were exposed or have dormant TB bacteria inside our body. X-ray negative suggest you are OK now. Try to explain the BCG vaccine to your doctor, and those knowledgable doctors will understand. BTW, BCG vaccine cannot protect you from TB, americans never get such shot.
我的医生说BCG疫苗产生的抗体基本只会维持7、8年,所以我们的抗体不是来自疫苗, 而是来自近期接 触到的活细菌,并且中国现在的带菌者数量是很可观的。x ray 没有问题不能说明我们 没有感染细菌, 只是可能不活跃而已。输了这么多,现在我觉得自己似乎已经被我的医生说服了。期待 大牛回复!
positive, case, bacteria the understand. shot.

The only purpose of taking those medicines is to kill the mycobacterium tuberculosis (causative agent of TB), otherwise it is helpless to take such toxic cocktail medcines. If your doctor is correct on that the antibody induced by BCG can only last for 8 years, then how to explain almost all chinese are TB positives at their age of >30? Will he assuming that all those chinese have dormant MT? My personal case is that I got two shots of BCG between 12 to 15, and TB positive at age of 31, my doctor did not suggest me take any medicine as X-ray is negative. FYI, interferon-gamma tests are more effective in detecting tuberculosis exposure in contacts than are traditional tuberculin skin tests (TST). Thereby, before you make your decision , you have to make sure you are indeed infected by MT. If there is dormant TB inside your body, you should take such medicine no matter how toxic it is. But there is no point of taking such medicine simply based on TB test, especially when negative on X-ray.
Negative is good news for you now. But it also means that you do not have immue in your body. so you need to be careful when back China.
