题目:EFFECTS OF ISOLATION AND SLAUGHTER STRATEGIES IN DIFFERENT SPECIES ON EMERGING ZOONOSES
报告人:崔景安教授,北京建筑大学理学院
摘要:Zoonosis is the kind of infectious disease transmitting among different species by zoonotic pathogens. Different species play different roles in zoonoses. Here, we established several cross-species models to describe the zoonotic pathogen transmission from wildlife, to domestic animals, to humans. Then we put three strategies into the basic model to control the emerging zoonoses. Three strategies are corresponding to control measures of isolation, slaughter or similar in wildlife, domestic animals and humans respectively. We analyzed the effects of these three strategies on control reproductive numbers and equilibriums and we took avian influenza epidemic in China as an example to show the impacts of the strategies on emerging zoonoses in different areas at beginning.

题目:具有应急群体免疫的天花传播动力学模型研究
报告人:张娟教授,华北电力大学数理学院
摘要:生物恐怖是当今人类面临的重大威胁,天花病毒被认为是最可能使用的生物制剂之一。免疫接种是防治天花流行的重要措施,但疫苗接种存在副作用,且疫苗对不同人群效果的差异影响天花的传播规律和模式。在多种接种策略中,应急的群体免疫的效能更好,最佳的接种比例可以降低接种疫苗的风险。本文根据天花的传播机理,考虑免疫效果的差异,建立了具有应急群体免疫的SEIR天花传播动力学模型,研究了不同的免疫策略对疾病流行的影响。
