ABSTRACT

Objective To analyze the epidemiological characteristics of malaria in Jiangxi Province from 2010 to 2014 and to provide a reference for malaria control in the whole province.Methods Data on malaria cases in Jiangxi Province from 2010 to 2014 were collected through the Disease Reporting Information System of Chinese Center for Disease Control and Prevention and Information System for Parasitic Diseases Control and Prevention.Descriptive epidemiological method was used to analyze the area distribution,time distribution and population distribution of the malaria cases.Results A total of 218 malaria cases were reported from 2010 to 2014 in the province,with an annual mean incidence of 0.097 3/100 000.One dead case was reported with a fatality rate of 0.46％(1/218).Of all 11 prefectures and 100 counties (cities,districts) in Jiangxi,65 counties (cities,districts)reported malaria cases.The top three counties (cities,districts) of malaria cases were Qingshanhu (22),Nanchang (15)and Jinxian (13),totally accounting for 22.94％ (50/218).The cases were reported through the whole year,without obvious seasonal peak.The ratio of male to female was 30.141.00.The age of the cases mainly distributed around the ages of 20-＜ 60 years,accounting for 94.49％ (206/218).The peak appeared in 40-＜ 50 years group,accounting for 32.11％ (70/218).The three major occupations of the cases were farmer,worker and migrant worker (131,60.09％).The cases were mainly imported from Africa and Southeast Asia,whose proportion of imported cases was 76.19％ (160/210) and 19.52％ (41/210),respectively.Conclusions The incidence of malaria is stable with a slight increase in Jiangxi Province from 2010 to 2014.Control of imported malaria cases will be the main task in the future.
