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.
Methods:
The data of registered malaria cases in Liaoning Province from 1951 to 2014 were collected and analyzed with epidemiological methods.
Results:
From 1951 to 2014, there were reported malaria cases each year. The peaks of incidence were in 1953, 1962 and 1973, the incidence rates were 136.67/100 000, 256.81/100 000 and 35.89/100 000 respectively and the numbers of patients were 27 862, 65 460 and 11 523, respectively. 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.
Conclusions:
The malaria endemic situation in Liaoning Province experienced the periods from outbreaks to basically elimination, and the long-term surveillance will be the further working emphasis.
