Methods The data of malaria cases were searched from the Disease Reporting Information System of Chinese Center for Disease Control and Prevention and analyzed with the descriptive epidemiological method for the epidemiological characteristics of malaria in Hubei Province in 2013. Results A total of 129 malaria cases were reported in Hubei Province in 2013 with the incidence of 0.02 /10 000,and all of them were imported cases,in which 86 cases with Plasmodium falciparum infection,32 cases with P. vivax infection,7 cases with P. ovale infection and 4 cases with P. malariae infection.The distribution of malaria cases was concentrated in Wuhan City（76 cases）,Yichang City（10 cases）,Xiangyang City（7 cases）and Huangshi City（6 cases）,accounting for 76.74% of the total cases. There was no significant seasonal variation in the reporting time of the cases. Totally 99.22% of the cases were male,the age distribution concentrated mainly on 20-49 years. The occupation distribution concentrated mainly on the worker,farmer,cadre staff and migrant worker. The main original areas of the imported cases were Africa（111 cases,86.05%）and Asia（17 cases,13.18%）.
