Methods The data of imported malaria as well as the case epidemiological in-vestigations were collected and retrospectively analyzed for the species composition,original countries,population distribution, regional distribution,onset situation,diagnosis,treatment,etc. in Qingcheng District from 2011 to 2016. Results The num-ber of imported malaria cases was 13 from 2011 to 2016. All the patients were confirmed by laboratory,and of which,9 patients infected with Plasmodium falciparum,1 with P. vivax,1 with P. ovale and 2 with mixed infections(P. vivax and P. falciparum). The yearly incidence of imported malaria presented an uptrend. The infection sources of all the patients were from African coun-tries,and the exported labor workers and travelers for business from malaria endemic areas were the high risk population. The re-ported time was mainly January,February,November and December(11/13,84.62％). All the patients were male,and the ma-jority of them(12/13,2.31％)were 21-60 years old. The median time from onset to seeing a doctor was 2.5 days and the median time from seeing a doctor to being diagnosed was 1.9 day. Six patients(46.15％)were diagnosed as other diseases at the first vis-it to a doctor,and one patient died of falciparum malaria because of delayed diagnosis.
