Abstract：We analyzed the epidemic characteristics of imported malaria in order to provide scientific evidences for eliminating malaria in Fujian Province. We collected the epidemiological data of imported malaria from 2011 to 2017, the SPSS software was used to analyzedthe species of malaria,source of infection and the Three Intervals distribution. At the same time, we did the multivariate Logistic Regression analysis on influence factors of cases identified by initial diagnosis of imported malaria. The results showed that a total of 632 imported malaria cases were reported from 2011 to 2017,and the main type of these cases were P. falciparum, accounting for 67.6% (427/632). All of the cases were imported,85.1%(533/632) were imported from Africa;50.6% (320/632) were mainly distributed in Fuzhou,the rest were scattered;the cases were reported the whole year, the onset time showed no significant seasonal variation; 85.1% (533/632)of the incidence of crowd were male young,males more than females,the sex ratio was 9.2:1(570/62); 82.9% (524/632) of the interval from onset to final diagnosis was in 10 days mostly; 72% (455/632) of the cases were identified by initial diagnosis. Among the influence factors of cases identified by initial diagnosis,there was a negative correlation between the rate of first diagnosis and the rate of taking antimalarial drugs before treatment (OR=0.175, 95%CI 0.061-0.509); two influence factors, which were informing doctor about the situation of malaria epidemic and initial diagnosis above the county level, were positive associated with the rate of first diagnosis (OR were 132.964 and 27.951, 95%CI were 41.601-424.973 and 13.285-58.806, respectively). The influence factor of occurrence of malaria was no reflection on the rate of first diagnosis(OR=1.496, 95%CI: 0.735-3.044).In order to adapt the epidemic situation of malaria at present in Fujian Province, the following control strategy was set up, control infection source, the health education of malaria knowledge for migrant workers must be strengthened,at the same time,in order to ensure the realization of the goal of eliminating malaria,the initial clinician on primary level should improve the diagnosis consciousness and diagnosis level for malaria. Early detection,early diagnosis and early treatment are important to minimize the occurrence of secondary transmission risk.
