[Abstract]:Objective to analyze the characteristics of malaria epidemic situation in China in 2016 and to provide scientific basis for effective implementation of malaria elimination strategies and measures. Methods the data of malaria epidemic in 31 provinces (municipalities, autonomous regions, not including Taiwan, Hong Kong and Macao) in 2016 were collected. Microsoft Excel 2010 software was used to analyze the general situation, regional distribution and species composition of malaria. The diagnosis and classification and the source of infection were analyzed. Results in 2016, a total of 3,321 malaria cases were reported in 687 counties (municipalities and autonomous regions) in 30 provinces (municipalities and autonomous regions) of China. Compared with 2015 (3,288 cases), the number of cases increased by 1.0%; the cases were mainly distributed in five provinces (autonomous regions), such as Yunnan (12.4%, 413 / 3 321), Sichuan (9.8%, 327 / 3 321), Jiangsu (9.3%, 308 / 3 321), Guangxi (9.22% 305 / 3 321), and Shandong Province (7.775% 3 321). Of the 3 321 malaria cases reported, 3 were local infections (0.1% of 3 / 3 321), all of which were vivax malaria. The infective sites were Yingjiang County, Yunnan Province (2 cases) and Chayu County, Tibet (1 case), and 3 317 cases (99. 9%, 3 317 / 3 321) were imported from abroad, distributed in 30 provinces (municipalities and autonomous regions) in China, and one case of transfusion infection, which was reported by Jiangsu Province, was a case of falciparum malaria. There were 15 clinically diagnosed cases (0.515 / 3,321), 3,306 confirmed cases (99.5kyum / 3306 / 3,321), 712 cases of vivax malaria (21.5% / 3.306), 2,158 cases of falciparum malaria (2158 / 3.306), 64 cases of malaria in three days (1.99-643.306), 311 cases of oval-shaped malaria (9.441 / 3.306), 61 cases of mixed infection. (1.8% 61 / 3 306). 14 provinces (municipalities directly under the Central Government, There were 185 severe cases (5.6%) and 15 deaths (0.515 / 3 321) in 8 provinces (municipalities and autonomous regions). Conclusion 99.9% of the cases reported in 2016 were imported malaria cases from abroad, and the local malaria transmission mainly occurred in the border areas of Yunnan and Linzhi region in Tibet. Surveillance and management of imported malaria abroad should be strengthened to prevent local secondary transmission.
