Abstract:
Objective:To understand the epidemiological characteristics of imported acute infectious diseases between 2008 and 2017 in the border areas of Yunnan province.
Methods:All the cases occurred between January 2008 and December 2017 and related information was from the Chinese CDC infectious disease report information management system, according to definition of imported cases diagnosed by clinicians. Epidemiological characteristics of the imported cases of related information were gathered.
Results:A total of 13 157 imported acute infectious diseases were reported from the border areas of Yunnan province, which accounted for 6.03% (13 157/218 284) of the total number of acute infectious diseases in the same areas from 2008 to 2017. Malaria, dengue fever and hand-foot-mouth disease were accounted for 56.05% (7 374/13 157), 21.82% (2 871/13 157) and 4.62% (608/13 157), of all the case, respectively. The number of imported malaria cases decreased annually. However, dengue fever showed a sharp increase. Peaks of the epidemics appeared as: May for malaria and October for dengue fever. Male patients were accounting for the majority (73.22%, 9 634/13 157), so as the patients with Chinese nationality (54.91%, 7 225/13 157). The age distribution appeared as: 67.12% (8 829/13 157) for the 15-44 year olds and 19.26% (2 535/13 157) were children below 14 years of age. Proportions of occupation appeared as: farmers (45.23%, 5 596/13 157), migrant workers (21.30%, 2 802/13 157) and children living at home (11.12%, 1 463/13 157). Most of the imported cases were coming from Myanmar and appearing in the following three counties: Ruili city, Tengchong city, and Yingjiang of Yunnan province. Cities/counties that with number of imported cases more than 10% of the local reported cases, would include Ruili city, Tengchong city, Zhenkang county and Mangshi of Yunnan province.
Conclusions:Imported acute infectious disease was a serious public health problem in Yunnan province, 2008-2017. The main imported acute infectious diseases were malaria, dengue fever and hand-foot-mouth disease. The majority imported cases were accounting for Chinese, male, young adults and farmers. It is also important for immigration workers to carry out surveillance, prevention and control programs on infectious diseases when working in neighboring countries.
