Tuberculosis is a “hidden” disease, but a much bigger problem than headline-grabbing Ebola. More than two billion people carry the TB bacterium, and at some point about 10% of them will develop the disease, which kills some 1.5 million victims per year (compared to 20,000 dead in the recent Ebola outbreak).
比如有几个能对人产生巨大帮助的目标。结核病是种“隐性”疾病，但带来的问题甚至超过引人注目的埃博拉。超过20亿人携带结核病菌，其中约10%的携带者会在某个时点发病，造成每年150万人死亡（与死于近期埃博拉病毒爆发的20，000人形成了鲜明的对照）。
