Malaria transmission is highly related to the natural factors such as temperature, rainfall and topography.Recently, the GIS/RS/GPS techniques were developed based on computer science and spatial analysis technology, which were widely used in data collection and analysis, establishment of mathematics model.This paper reviews the applications and development of GIS/RS/GPS techniques in the studies of relationship between natural factors and malaria transmission.

Objective To determine the key interventions transferring from the control to elimination of malaria in China so as to provide the basic information for achieving malaria elimination. Methods Based on the data collected from the document entitled of The National Annual Report on Schistosomiasis,Malaria and Echinococcosis,published by the National Institute of Parasitic Diseases of Chinese Center for Disease Control and Prevention,the malaria incidence and intervention data were se?lected only in the typical endemic provinces during the period of 2004-2010. The correlation between the incidence and interven?tions in the target provinces was analyzed based on the Panel Data Regression Model,and the key interventions were deter?mined. Results Four provinces namely Anhui,Yunnan,Hainan and Henan were targeted with 87.56%of the national malaria figures from 2004 to 2010. When Y was given as vivax malaria incidence,X1 as the log of the number of historical cases receiving radical treatment in the pre?transmission stage(RTPT)(F=14.53,P<0.01,R2=0.72),X2 as the log of risk population receiv?ing RTPR(F=15.90,P<0.01,R2=0.71)and X3 as the number of technicians trained in microscopy(F=11.53,P<0.01,R2=0.61),three space?fixed effect models were established respectively,and X1,X2,as well as X3 had negative effects on Y value. When Y was given as falciparum malaria incidence,X1 as the accumulated technicians trained in microscopy(F=11.06,P<0.01,R2=0.87),X2 as the log of technicians trained in entomology(F=15.28,P<0.01,R2=0.89),two two?way(space and time)fixed effect models were established respectively,and both X1 and X2 had negative effects on Y value. Conclusion RTPT among historical patients and at?risk populations as well as microscopy training influences the variation of vivax malaria inci? dence,while the significant interventions of microscopy training and vector control training indicate that the integrated measures with strengthened capacity in diagnosis and vector control are of importance in the control of falciparum malaria transmission.

Objective To investigate the malaria knowledge of CDC staff and their demands on related training in malaria non⁃endemic areas，so as to provide the reference for planning the appropriate curriculum. Methods All the participants who were the staff of county CDCs all over Qinghai Province and attended the provincial training workshop were surveyed. A self⁃administered questionnaire survey was carried out and the data was statistically analyzed. Results A total of 115 participants were involved in this survey. They were mostly（85.21%）from county CDCs. The general knowledge of malaria among the respondents was well，and the average rate of correct answers was 70.35%. However，the answers to the general knowledge of malaria and anti⁃malaria treatment were not well enough. The rates of correct answers were 61.96% and 48.99% respectively. The differences among the groups of job title ranking，department of working and level of CDC were not significant（F = 0.13-2.02，all P > 0.05）. The number of correct answers was significantly increased after the training course. The average score after the training was 79.20±15.16 while the pre⁃training score was 70.34±17.46（t = 3.86，P < 0.05），especially in the answers to general malaria knowledge and malaria surveillance and response（t = 4.30，4.97，both P < 0.05）. The general knowledge of malaria was considered as the most need of training as 80% of the respondents voted“Yes”，according to the demand analysis. There was no significant difference among the different groups（F = 0.61-3.11，both P > 0.05）. Conclusion The malaria knowledge is well mastered by the staff of CDCs in Qinghai Province，and the further training courses are requested and addressed in the target areas such as general malaria knowledge，anti⁃malaria treatment，malaria surveillance and response.
