【Abstract】 Objective To guide the vector control after earthquake by hazard analysis and critical control points (HACCP) system. Methods Vector control was carried out according to seven process of HACCP system. The seven processes were as follows: hazard analysis, critical control point, critical limit, critical limit evaluation, corrective measure, certification program and records and files. Results Nine critical control points (CCP) were confirmed. The main vectors needed to control were flies and Phlebotomus chinensis. The environments around the corpuses, life garbage and lavatories should be preferred to be treated. Critical limits (CL) were established according to the CCPs. Eight CLs was rectified. Ten records and files were established. At the temporary garbage site and the human excrement place, malodor decreased by 50%-100%, and the flies density also declined to 87.5%-100%. The killing rate to P.chinensis was 100%. The health level of temporary lavatories accorded with National Class Ⅲ. Epidemiology investigation showed the incidence rate of disease was lower in 2008 than that in 2005 and 2007 respectively. Most importantly, the vector?borne diseases did not occur. Conclusion Application of HACCP system in the vector control at the earthquake disaster areas provides a case for disease control in unexpected public health event and natural disaster in the future.

Objective To learn the influence of the earthquake in Wenchuan on vectors and vector borne disease,grasp timely the vector species and its density dynamics,and provide a reliable basis for the risk assessment of vector borne disease.Methods Investigate the density of rats,mosquitoes and flies in a large scale.Monitor the density of flies in the tents of living areas,trash-dropping places and washrooms daily.Survey the rats density with rat folders method,flies density with sticky flies plate and eyeballing method,mosquito density with trap-mosquito method and eyeballing method.Results The result showed that the density of rats and mosquitoes was relatively lower,and the density of flies was under the reference index as a whole.The flies density was higher in some places because there was still some trouble in the garbage disposal of kitchens and washroom.Conclusion We should strengthen the health and sanitation education to the victims,and try our best to do the disinfecion and vector monitor works at the victim temporary habitation.
