![]() ![]() Since then, substantial progress has been made. The National Malaria Elimination Programme (NMEP) was launched in 2010. Overall, malaria cases have sharply declined with only 14,491 malaria cases reported in 2009. Following an epidemic peak in 2006, control efforts were consolidated with the formulation of the National Malaria Control Programme (NMCP) in 2006. Since then, the malaria burden has greatly declined, but it has remained a serious public health problem in China with periodic outbreaks. Owing to its substantial public health importance, a Malaria Control Programme was initiated in 1955. Prior to 1949, the annual number of malaria cases in China was estimated to be 30 million. Anopheles sinensis, Anopheles minimus, Anopheles dirus, and Anopheles lesteri are common malaria vectors in China. falciparum are the main malaria parasites, with the former being the most dominant species. Malaria is caused by five species of Plasmodium: Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, Plasmodium malariae and Plasmodium knowlesi. Malaria is a life-threatening infectious disease severely affecting vulnerable communities in tropical and subtropical regions where the environment is suitable for transmission Although malaria transmission appears to be declining worldwide as a result of control interventions, the 2015 estimation indicates that there are 214 million cases and 438,000 malaria deaths. Further studies are required to examine the spatial changes in risk of malaria transmission and identify the underlying causes of elevated risk in the high-risk areas. falciparum malaria shifted from the west to the east of China. Both malaria types showed significant spatial and spatiotemporal variations. The spatial and space–time cluster analysis identified high-risk areas and periods for both P. falciparum malaria were detected in northern Anhui province and western Yunnan province, respectively, during 2005–2009. The most likely space–time clusters of P. falciparum, the clusters included several counties of western Yunnan province from 2005 to 2011, Guangxi from 2012 to 2013, and Anhui in 2014. vivax was detected in northern Anhui province between 20, and western Yunnan province between 20. falciparum malaria showed spatial autocorrelation. Spatial and space–time scan statistics were applied to detect spatial and spatiotemporal clusters, respectively. Global Moran’s I statistics was used to detect a spatial distribution of local P. This study aims to understand the spatial and spatiotemporal distribution of Plasmodium vivax and Plasmodium falciparum malaria in China during 2005–2009. A better understanding of the spatial and temporal characteristics of malaria is essential for consolidating the disease control and elimination programme. Despite the declining burden of malaria in China, the disease remains a significant public health problem with periodic outbreaks and spatial variation across the country.
