RESUMO
OBJECTIVE: To analyze the epidemiological characteristics of malaria in Leshan City, so as to provide the evidence for formulating the strategy and measures for consolidating the achievements of malaria elimination. METHODS: The data of epidemiological characteristics of malaria in Leshan City from 1950 to 2015 were collected and analyzed with the descriptive epidemiology method. RESULTS: There were four larger scale epidemics of malaria in Leshan City from 1950 to 2015. The order of malaria in infectious diseases dropped from the first to the twentieth. The peak season for malaria epidemics ceased. The Plasmodium species, patient age, occupation and sex distribution of malaria were different in the different periods. In November 2016, the whole city achieved the national standard for malaria elimination. CONCLUSIONS: After years of prevention and control, the epidemiological characteristics of malaria have changed significantly in Leshan City, and the effect of anti-malarial measures is significant. In the future, we should strengthen the monitoring, and prevention and control of imported malaria.
