To understand the malaria epidemic situation in Chengdu City, so as to provide the evidence for effectively carrying out the malaria elimination work. The data of imported malaria in Chengdu City from 2012 to 2016 were collected from the Disease Surveillance Information Reporting System of Chinese Center for Disease Control and Prevention and analyzed respectively. A total of 240 imported malaria cases were reported in Chengdu City from 2012 to 2016. In detail, 68.75% of the cases were falciparum malaria cases, 20.41% were vivax malaria cases, 2.50% were quartan malaria cases, 6.25% were ovale malaria cases, and 2.08% were mixed infections. Among them three patients died, with a mortality of 1.25%. All of the cases were infected overseas, among which 224 patients returned from Africa and 16 patients from Southeast Asia. The annual average morbidity was 0.28/100 000, and there was a significantly difference among annual average morbidities ( = 23.87, < 0.001). There were malaria cases reported in every month, and no significantly difference among seasons ( = 0.833, > 0.05). The number of overseas imported malaria in Chengdu City increases year by year. The effective measures to control the overseas imported malaria should be strengthened to consolidate the achievements of malaria elimination.
