Abstract


Background The monitoring and control of the border crossings medical vectors is important and port health control and communicable disease surveillance system and foundation work. With the rapid development of economic globalization and the aviation industry, the importance of medical vectors Airport Port Monitoring and control work is even more prominent. Shenzhen, Beijing, Shanghai and three airport successively certified by the World Health Organization for the International Health airport, port health control template to improve the international image of an airport in China at the same time, strive for international health Airport to other airports. Hangzhou Xiaoshan International Airport is actively seeking to declare the International Health airport. Research purposes to identify the ports existing media biological species, and to provide basic information to carry out long-term monitoring and research in the future. According to the Port of medical vector population composition, density and seasonal fluctuation data, summarize the development of the actual situation of the Hangzhou Xiaoshan International Airport control medical vectors program proposed to improve port health, infectious diseases prevention and control work measures. Home and abroad, infectious diseases, analysis of the risk of transmission of infectious diseases of the crossings by the medical vectors, and propose effective policies and measures to minimize the risk of transmission of infectious diseases at the port level, to ensure that the transfer of international quarantine and surveillance of communicable diseases do not occur into the outgoing, abroad health off. Learn from the the International Health airport in Beijing, Shanghai and other vector control experience and compliance with the relevant standards of international, national vector control, to carry out the pre-master's degree thesis of Zhejiang University, Hangzhou Xiaoshan International Airport Medical Vectors monitoring and control research studies and to provide basic information and theory basis for the Hangzhou Xiaoshan International Airport PARTICIPATING International Health airport to lay the foundation. Research methods, from April 2001 to March 2002, a one-year on-site investigation, experimental study. Medical vectors Hangzhou Xiaoshan International Airport, population density, seasonal fluctuation Survey within the space include: medical media animal population distribution, density and seasonal fluctuation; of medical animal body surface parasitic flea, cricket, leathery hide the truth, chigger cochlear Medical insect population density and growth and decline; capture animal lung tissue detected renal comprehensive levy hemorrhagic fever virus antigen. SPSS statistical software on survey data obtained using the t test, analysis of variance, chi-square test and other statistical methods for processing and analysis. National vector control standard, compared with the airport's three airports in the surrounding areas and have been international health analysis. Results in the investigation of the Chinese Communists captured 644 small medical animal parasitic insects that were seized were surface 137 by the classification and identification, to determine medical vectors 5 orders 7 families, 10 genera and 13 species found in the various habitats of the Hangzhou Xiaoshan International Airport Landscape . Medical animals: clear the average density of the wild habitat (artificial shrub) (l .90% 20.24%) 6.89% the dominant species Apodemus agrarius 75.55%. The indoor terminal dominant species habitat the Rattus norvegicus 50.54% and Apodemus agrarius 26.88%; the indoor freight warehouse habitats Apodemus agrarius 56.63% Rattus norvegicus 33.73%; the indoor special habitats catering food company Mus musculus ( 90%). The indoor habitats an average density of 1.83% (O 6.96%). Dynamic between the point of the investigation Journal of Zhejiang University in Hangzhou Xiaoshan International Airport medical vectors monitoring and control constituting a significant difference (xZ = 198.78, only 0.01). Indoor habitats and wild habitats annual average density of the existence of a significant difference (paired t-test, t = 6 .544, df = 11, P lt; 0.01). Animal breeding: the average animal pregnancy rate of 23.73%, with an average litter size of 5.09, July pregnancy rate was the highest at 47.62 percent, from November to next February for breeding trough, not found in pregnant animals. Seasonal fluctuation of animal populations: Apodemus agrarius bimodal (June 5, October), Rattus norvegicus single peak (September). Animal body surface parasitic Medical insect: cicadas were found hiding mesh 3 families and 4 genera and 6 species of animals total dyed leather cochlear 34.01% 60.26% (7.69% spoon), the total leather conceal index of 1.7624 (.0769 to .2667). The dominant species unnamed leather cochlear 46.74% and Grignard blood Li conceal 34.48%. Leather conceal population fluctuation was the peak shape of the two low and one high school. Dyed leather cochlear rate between each survey month there were significant differences (xZ = 57.719, only 0.01). Habitats dyed leather hiding rate were significantly different (xZ = 9 .657, only 0.05). Seized ranging from mouse somatic single flea 2 are anisus, the total dye flea was 0.31%, the total flea index of 0.0031. Not found the chigger hiding. Cricket is not found. As of February 2002, captured on March 78 the Small Mammals animals, direct immunofluorescence detection of lung tissue HFRS virus antigen test results were negative, of small mammals in animals with the virus was O. Hangzhou Xiaoshan International Airport animal density exceeds the national port health control standards, and a nation that loves Committee standards, there are significant differences, and there is a big gap between the three airports have created the International Health airport. Zhejiang University, a master's degree thesis Hangzhou Xiaoshan International Airport monitoring and control of medical vectors conclusions of the research results Hangzhou Xiaoshan International Airport in the monitoring and control of vectors with the requirements of the national civilization Health ports and international health airport there is a certain gap. Airport medical vectors are few, but widely distributed, community, high density, reproduce prolifically, the surface parasitic insect species and density are likely in the future time increasing, there is the danger of infectious disease epidemics and outbreaks sex. According to the the three International Health airport advanced media biological monitoring and control experience, combined with the actual situation of the investigation, monitoring and control of the work and medical vectors created to further develop the Hangzhou Xiaoshan International Airport International Health airport, and put forward specific recommendations .
