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

本文研究了热带、亚热带地区自然地理环境的变化与蚊媒疾病流行的关系。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受本研究的影响，以预测蚊子传播的传染病的趋势。本研究的最终目标是应用地理信息系统（GIS）工具开发可持续的和适当的控制措施。1）利用遥感卫星数据和地理信息系统功能开发了一种景观方法来识别环境参数。研究表明，地表水量、距海岸线距离、雨季和旱季的季节变化可作为确定亚尖按蚊幼虫密度的环境参数。建立了指数分布的广义线性模型， ...更多信息 一个的分布。2）在所罗门群岛的瓜达尔卡纳尔岛进行了疟疾防治的GIS应用研究。1992年对国家疟疾防治方案进行了改组，采取了分发浸药蚊帐和管理病人的策略。1992年为最高流行期，1998年由于MCP行动而稳步下降。自1998年底以来，瓜达尔卡纳尔岛的紧张局势加剧，土著居民和马莱塔定居者之间的种族仇恨爆发为几次叛乱。1999年3月，马共被迫暂停在瓜达尔卡纳尔岛的活动。所罗门群岛的首都霍尼亚拉有大量从瓜达尔卡纳尔岛流离失所的人涌入，严重扰乱了包括疟疾控制在内的保健系统。我们的研究小组也被迫暂停任何实地研究活动，直到2000年底才完成其初步研究计划。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。泗水在过去5年中记录了约9，000例DF患者。应用地理信息系统将病历与时空参数进行整合，并进行季节变化、发病率和聚类分析。本研究旨在为泗水市政服务提供政策制定数据。4）此外，通过与泰国和中国的对口研究所或大学的合作研究，收集了疟疾、登革热和肠道寄生虫的实地数据。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.
