Studies on the Association between Environmental Change and Vector-Borne Diseases in Tropical Area Using Geographic Information System

研究了热带、亚热带地区自然地理环境变化与蚊媒疾病流行的关系。对印度尼西亚龙目岛或瓜达尔卡纳尔岛、所罗门群岛的疟疾和印度尼西亚泗水的登革热进行了这项研究，以预测蚊子传播的传染病的趋势。这项研究的最终目标是利用地理信息系统(GIS)工具制定可持续和适当的控制措施1)开发了一种利用遥感卫星数据和地理信息系统功能来识别环境参数的景观方法。将地表水容量、距海岸的距离和雨季或旱季的季节变化作为环境参数来确定亚种按蚊幼虫密度。建立了指数分布的广义线性模型来估计分布的…更多的是对一个人的不满。2)尝试将地理信息系统工具应用于所罗门群岛瓜达尔卡纳尔岛的疟疾控制。1992年重组了国家疟疾控制方案，采取了分发浸泡蚊帐和管理病人的策略。疫情高峰期在1992年，由于MCP的实施，疫情在1998年稳步下降。自1998年底以来，瓜达尔卡纳尔岛的紧张局势加剧，土著居民和玛莱塔定居者之间的种族仇恨爆发为几次叛乱。1999年3月，MCP被迫暂停在瓜达尔卡纳尔岛的活动。所罗门群岛首都霍尼亚拉的人口从瓜达尔卡纳尔岛涌入，严重扰乱了包括疟疾控制在内的医疗保健系统。我们的研究小组还被迫在没有完成初步研究计划的情况下暂停任何实地研究活动，直到2000年底。3)登革热/登革出血热是印度尼西亚泗水最重要的公共卫生问题。在过去的5年里，在泗水记录了大约9000例DF患者。应用地理信息系统将病历与时间和空间参数进行整合，并对其季节变化、发病率和聚类分析进行检验。4)此外，通过与泰国对口研究所或大学和中国的合作研究，收集了疟疾、登革热和肠道寄生虫的现场数据。较少

The association between the change of natural and geographical environment and the endemic of mosquito-borne diseases was studied in tropical or sub-tropical area. Malaria in Lombok Island, Indonesia or Guadalcanal Island, the Solomon Islands and dengue fever in Surabaya, Indonesia were subject to this study in order to predict the trends of infectious diseases transmitted by a mosquito. The final goal of this study was designed to develop sustainable and appropriate control measures applying geographical information system (GIS)tool.1) A landscape approach using Remote Sensing satellite data and Geographic Information System functions was developed to identify environmental parameters. The volume of surface water, site distance from coast, and seasonal variation of whether rainy season or dry season were considered as environmental parametersfor determining larval Anopheles subpictus densities. Generalized Linear Model with exponential distribution was developed to estimate the distri … More bution of An. subpictus larval densities, and the predictions of larval densities adopted in the model were matched with the observed data.2) GIS tools were tried to apply to malaria control in Guadalcanal Island, the Solomon Islands. The National Malaria Control Programme (MCP) with a tactics of distribution of impregnated bed-net and management of patients was reorganized in 1992. The highest epidemic was in peak in 1992, and fell steadily by 1998 due to the MCP operation. Since the end of 1998, tension has increased on Guadalcanal, as ethnic hatred between the aboriginal population and the Malaitah settlers has flared into several rebellions. The MCP was forced to suspend activities on Guadalcanal in March 1999. Honiara, the capital of the Solomon Islands with an influx of population displaced from Guadalcanal, has seriously disrupted the health care system including malaria control. Our research team was also forced to suspend any field research activities until the end of 2000 without completion of its initial research plan.3) Dengue fever/ dengue hemorrhagic fever is the most important public health problems in Surabaya, Indonesia. About 9,000 cases of DF patients were recorded in the last 5 years in Surabaya. GIS was applies to integrate patient record with spatial and temporal parameters, and seasonal variation, morbidity rate and clustering analysis was tested. This study was designed to provide data for policy making to Surabaya municipal service.4) In addition, field data on malaria, dengue fever and intestinal parasite were collected through collaboration study with counterpart institute or university in Thailand and China.
