AIDS, incredibly, has just been named, in the past month, a chronic disease, meaning that a 20-year-old who becomes infected with HIV is expected not to live weeks, months, or a couple of years, as we said only a decade ago, but is thought to live decades, probably to die in his '60s or '70s from other causes altogether.
更难以置信的是，艾滋病， 在上个月里刚被定义为一种慢性疾病， 也就是说一个20岁感染艾滋病毒的人， 要是在十年前，人们会觉得他活不过几周 几个月，至多几年， 但现在被认为会再活数十年， 也许会在他六七十岁时死于其他并发症。
