Abstract
To analyze the epidemic characteristics of the imported malaria cases in Guangxi Zhuang Autonomous Region in 2014, so as to assess the transmission risk and explore the prevention and control strategy. The data of the malaria epidemic situation in the network direct report system of Guangxi in 2014 and the annual report of malaria epidemic situation in 14 cities were collected. The epidemiological information of the imported malaria cases was analyzed. A total of 184 malaria patients were reported in Guangxi in 2014, with a descent rate of 85.29% when compared to that in 2013 (1 251 cases), and the incidence rate was 0.35/100 000. All the cases were imported from abroad, and four species of Plasmodium were found in their blood samples. The number of falciparum malaria cases was the most (49.46%), followed by the ovale malaria cases (32.07%). All the cases were distributed in 32 counties (districts) of 11 cities, and 65.76% of them were distributed in Shanglin County. Most of the cases were male (98.37%), and those aged in 20-49 years accounted for 87.50%. The imported cases came from 14 countries of Africa (86.41%) and 2 countries of Southeast Asia (13.59%), in which, 48.37% of the cases were imported from Garner. The main occupation of the cases in abroad was gold mining work (86.96%). The cases were reported all the year around, with no obvious seasonality. The interval time of back home to attack of the patients with tertian malaria and ovale malaria was longer. Africa and Southeast Asia is the main source of imported malaria cases in Guangxi, and the migrant workers returning home may have the risk of malaria recurrence, which should be paid enough attention to.
