每日一词学英语(48): complication

英国一名38岁妇女昨天(June 14, 2009)死于swine flu，死者曾患有中风等疾病及一些并发症。Harry Burns, Scotland's Chief Medical Officer, told The Times that pregnancy could put a strain on woman's bodies which might make them more susceptible to infection. It can also exacerbate existing chronic respiratory conditions which also lead to complications with swine flu.
