ABSTRACT

Dengue disease as a still prevailing main health issues in tropical and sub-tropical countries including Sri Lanka. A staggering number of 47000 cases with 78 deaths cases were recorded in 2016. Both natural and socio-economic factors have provided a conducive environment to conveyance of the disease. This study consists of two data components. Data collecting for this research is based on the primary and secondary data. Primary data were collected specifically for the research through a questionnaire, an interview, observations, and a case study. Primary data and information were gathered using a questionnaire with 75 patients and by in-depth interviews. However, the aim of this study is to analyze the geo-spatial pattern immerging factors of dengue epidemic in the Matara District. Correlation, regression analysis and the ARC GIS 10.1 techniqcs were used in the process to mapping and statistics analysis. There are two important trends related to dengue outbreak in the district and whole district seemed to be at the epidemic levels. The study area was selected because of the highest number of dengue cases recorded during the period from 1997-2014 and monthly cases from January 2011-December 2015. Urban areas seemed to be favourable for mosquitoes with a copiousness supply of plastic containers, discarded bottles, tins, tires, water coolers, house plants, air conditioners and places where rain water set stuck or stored providing the suitable mosquitoes breeding grounds. Matara district is an area with high population density expediency a development of transport system as well as a climatic change. Upon the observation of the distribution of annual dengue cases in 2015, spatial pattern of the district has played a major role. It is clear that the epidemic cannot be eradicated totally without proper community reaction, changes in attitudes and acquiring knowledge.
