When Germ Warfare Happened

I have never heard much about this:

When Germ Warfare Happened by Judith Miller, City Journal Spring 2010: "Jiang is one of 15 elderly Chinese men and women whom Zhu is treating in his simple village clinic for what locals label “rotten leg disease.” A definitive diagnosis is no longer possible so many decades after the initial exposure and secondary infections. But Chinese, American, and other Western physicians who have examined the survivors, documented their histories, and photographed their wounds claim that they are victims of the most gruesome biological warfare attacks in modern history."
