[Epidemiological characteristics of malaria in Liaoning Province from 1951 to 2014].

OBJECTIVE
To explore the epidemiological characteristics of malaria in Liaoning Province from 1951 to 2014, so as to provide the evidence for further control of the disease.

From 1977 to 2014, the incidence rates were all less than 1/100 000. From 1951 to 1980, the occupations of patients were mainly farmers, and from 1981 to 2014 were mainly workers, farmers and exported laborers.
