Abstract
To analyze the epidemiological characteristics of malaria prevalence in Danyang City from 2004 to 2015, so as to provide the evidence for formulating the strategy of prevention and control of malaria. The data of malaria serum tests, the reported malaria cases from the Internet Reporting System, and the epidemiological case survey from 2004 to 2015 as well as the mosquito monitoring data from 2008 to 2015 were collected and analyzed. From 2004 to 2015, 58 malaria cases were reported in Danyang City, with an average annual incidence rate of 0.6/105. Among the cases reported, vivax malaria accounted for 65.52% (38/58), falciparum malaria accounted for 5.17% (3/58), oval malaria accounted for 1.72% (1/58), and unclassified subtype accounted for 27.59% (16/58). The local infection cases accounted for 31.03% (18/ 58), and the imported cases accounted for 68.97% (40/58). There were no local infections since 2011. Anopheles sinensis, the only malaria vector in Danyang City, was still prevalent, but its density was low. Imported malaria poses a serious threat to the malaria elimination achievements in Danyang City, and the surveillance and disposal of imported malaria need to be strengthened.
