ABSTRACT
Objective To grasp the malaria epidemic situation in Changzhou City from 2010 to 2014,so as to provide the ev?idence for formulating and adjusting malaria control strategies and measures. Methods The epidemiological data of malaria cas?es in the special report system from 2010 to 2014 were collected,and the malaria epidemic situation and the diagnosis and treat?ment of malaria patients were analyzed. Results There were 132 malaria cases reported in Changzhou City from 2010 to 2014, with a decrease of 27.47%compared to 182 cases from 2005 to 2009. Among the 132 cases,2 cases were local infected cases and the remaining 130 cases were imported cases. Four cases were clinically diagnosed and 128 cases were laboratory con?firmed,with 97 cases of malignant malaria,14 cases of vivax malaria,13 cases of ovale malaria,and 4 cases of quartan malar?ia. The 132 cases were distributed in five districts:56 cases in Jintan City,51 cases in Liyang City,19 cases in Tianning Dis?trict,3 cases in Wujin District,and 3 cases in Xinbei District. The median duration between the onset and treatment of the dis?ease was 2 days,and the median duration between the diagnosis and treatment was 1 day. The diagnosing units were concentrat?ed on the county?level disease control agencies,and medical institutions at county and municipal levels,accounting for 92.42%(122/132). From 2011 to 2014,there were no local malaria cases. Conclusions From 2012 to 2014,there have been no local malaria cases in Changzhou City,and the goal of eliminating malaria has been achieved basically. However,there are still many imported malaria cases,and the infected species are diverse. Therefore,imported malaria is still the key of malaria prevention and control.
