It should be a shock to most in the Western world that TB (short for tuberculosis) an ancient disease can raise its ugly head again.
I learned about XDRTB while reading Mountains Beyond Mountains, the bibliographical sketch of Paul Farmer (a must read by the way).
The fact that the disease is taking its toll with over 1.5 million people dying every year is shocking, specially considering that most people die within weeks of being diagnosed.
Doing my bit here by linking to a short slide show put together as a TED prize.
