Abstract:

The 2014 malaria epidemiological data reported through the annual malaria statistics reporting system were collected and analyzed. A total of 3 078 malaria cases were reported in 680 counties of 30 Provinces/Municipalities/Autonomous Regions（P/M/A）(except Inner Mongolia) in 2014, decreased by 25.4% compared with the 4 128 cases in 2013. The incidence rate was 0.022 6/10 000. More cases distributed in Yunnan（17.3%, 533/3 078）, Jiangsu （11.5%, 355/3 078）, Sichuan（8.6%, 266/3 078）, Henan（7.0%, 216/3 078） and Zhejiang（7.0%, 215/3 078） Provinces. Of all the cases, 56 （1.8%） were indigenous cases, mainly from the border area of Yunnan （comprising 9 counties） and the Tibet Autonomous Region（one county）. Locally-infected falciparum malaria was only found in Yingjiang County （4 cases） and Cangyuan County （2 cases） of Yunnan. Indigenous malaria prevalence was of over 1/10 000 in Motuo County and Yingjiang County. There were 3 021 abroad-imported cases of malaria（98.1%）, which widely distributed in the 30 P/M/As. In addition, one case of quartan malaria with long latency was reported in Guangdong Province. Of all the reported cases, 3 057 （99.3%） were further confirmed by plasmodium species, comprising 846 cases of vivax malaria（27.7%）, 1 882 cases of falciparum malaria（61.6%）, 3 cases of quartan malaria（1.7%）, 231 cases of ovale malaria（7.6%）, 44 cases of mixed infections, and one case of P. knowlesi malaria. Furthermore, 170 cases（5.5%） with severe conditions were reported in 16 P/M/As, and 25 deaths were reported in 15 P/M/As. In summary, remarkable achievements have been made in eliminating malaria in China, despite increases in imported cases. The border areas of Yunnan and Motuo County of Tibet Autonomous Region re-main the key regions for malaria elimination. Efforts are needed to reinforce the management of imported cases and the treatment of complicated malaria.
