中文摘要:

采用网络爬虫技术分析2013年中国各省份通过活禽贸易携带H7N9禽流感病毒活禽的可能传播方向和范围，并预测疫情发展趋势。数据分析显示，有18个省份存在高感染风险，其中13个省份截止2014年2月已有报告病例。预测5个元感染风险的省份迄今未报告病例。

英文摘要:

Objective To analyze the epidemiological characteristics and changing trend as well as the related affecting factors of hepatitis C in China.Methods Data analysis was performed based on the case-reporting data of hepatitis C from 1997 to 2011,using SPSS 19.0.Results The number of reported cases and incidence of hepatitis C had been increasing annually since 1997,especially in 2004.The hepatitis C reported incidence increased from 3.03 per 100 000 in 2004,to 12.97 per 100 000 in 2011.The 15 to 49 age group accounted for more than 50% of all the reported cases,seen in every year.The number and proportion of hepatitis C reported cases among those over 50 year-olds had an annually increase.From 2005 to 2011,the number of cases in both urban areas and rural areas increased annually,while the urban-rural ratio decreased from 1.47 in 2005 to 0.99 in 2011.There appeared an increasing trend of hepatitis C reported incidence in China,with most of the high reported incidence of hepatitis C fell in the northern parts of China.74.8% of the HCV/HIV co-infected cases had histories of intravenous drug use,plasma donation,blood transfusion or surgical operation.Conclusion The reported number and incidence of HCV infection had been increasing annually.To develop a more realistic control measures for hepatitisv C,it is necessary to strengthen the monitoring program and carrying out specific epidemiological study among target groups and key areas.
