Abstract: Objective Objective To understand the epidemic situation and characteristics of malaria in Yunnan Province，so as to pro? vide the reference for malaria elimination. Methods Methods The data of malaria reported in the information system were collected and analyzed in Yunnan Province from 2011 to 2013. Results Results From 2011 to 2013，totally 2 256 malaria cases were found in Yun? nan Province，with a morbidity of 0.162 8 per million and three of them were death cases. The local cases mainly distributed along the boundary and accounted for 29.48%，while the imported cases mainly came from Myanmar and accounted for 70.52%. The number of endemic counties with local malaria cases decreased from 37 to 10 during the three years. The number of import? ed cases reached the peak in May and the local cases in June. The patients were mainly aged from 20 to 49 years old（accounted for 70.58%），and 85.24% of the cases were peasants and laborers. Totally 86.66% of cases were laboratory confirmed cases， and 13.14% were clinically diagnosed. The proportions of cases reported by hospitals，health service centers and CDCs were 33.02%，37.06% and 29.92%，respectively. Conclusions Conclusions The prevalence of malaria in Yunnan Province decreased from 2011 to 2013. The work of malaria cases double?checked by province?level CDCs is effective. However，the awareness and accurately diagnostic capability of clinical doctors still should be strengthened.
