To trace the source of the avian H7N9 viruses, we collected 99 samples from 4 live poultry markets and the family farms of 3 patients in Hangzhou city of Zhejiang province, China. We found that almost all positive samples came from chickens and ducks in live poultry markets. These results strongly suggest that the live poultry markets are the major source of recent human infections with H7N9 in Hangzhou city, Zhejiang province of China. Therefore, control measures are needed, not only in the domestic bird population, but also in the live poultry markets to reduce human H7N9 infection risk.
为了追溯 H7N9 禽流感病毒的来源，我们从中国浙江省杭州市的 4 个活禽市场和 3 位患者的家庭农场采集了 99 个样本。我们发现，几乎所有的阳性样本都来自活禽市场的鸡和鸭。这些结果强烈提示，活禽市场是中国浙江省杭州市近期人感染 H7N9 的主要来源。因此，需要采取控制措施，不仅要针对国内禽群，还要针对活禽市场，以降低人感染 H7N9 的风险。
