The spatio-temporal distribution of malaria in Thailand from 2006-2015

Abstract

Background and Objective: Malaria is a vector-borne disease in the tropical zone which the one of major health problem in Thailand. This study is aimed to determine the spatial and patterns of malaria and to identify clustering in Thailand during 2006-2015. Methods: Data were obtained from inpatient reported by Ministry of Public Health, was obtained during 2006 to 2015. The spatio-temporal technique including, local indicators of spatial autocorrelation technique and cluster analysis at the country level, were conducted for the spatio-temporal distribution of malaria incidence. Results: Outbreaks occurred in three waves over the past 10 years with the lowest incidence rate occurring at the beginning of each wave. The incidence of malaria in Thailand shifted from the western to the southern and the north-eastern regions. A spatial clustering analysis identified multiple clusters of high incidences in provinces in southern, Thailand from 2006-2015 and differed cluster in north-eastern region (Si Sa Ket). Conclusion: A malaria clustered map will be best technique for identified the risk areas, which the one step of surveillance. It has been considered effectiveness prevention plan and allocated a healthcare resources of vector-borne diseases.
