[Epidemiological analysis of malaria prevalence in Jiangsu Province in 2016].

OBJECTIVE: To understand the malaria epidemic situation and characteristics in Jiangsu Province in 2016, so as to provide the evidence for formulating and adjusting the strategy and measures for malaria elimination.

METHODS: The data of malaria cases in Jiangsu Province in 2016 were collected from China's Routine Diseases Surveillance Information System (CRD-SIS) and analyzed statistically.

RESULTS: Totally, 308 malaria cases were reported in Jiangsu Province in 2016, and the cases decreased by 23.95% compared to 405 malaria cases in 2015. Except for 1 malaria case that was caused by blood transfusion, the rest patients were all imported. Among the 308 cases, 237 were infected with Plasmodium falciparum , 11 were infected with P. vivax , 8 were infected with P. malariae , 51 were infected with P. ovale , and 1 was mixed infection. Among all the cities in Jiangsu Province, the numbers of imported cases of Nantong (53 cases), Huai'an (41 cases), Taizhou (40 cases), Lianyungang (36 cases) and Yangzhou (29 cases) ranked in the top 5, and the total malaria cases in the five cities accounted for 64.61%.

CONCLUSIONS: There were no local malaria cases in Jiangsu Province for 5 consecutive years up to 2016. Although the imported cases decreased slightly compared to those in 2015, we still should strengthen the surveillance of imported malaria cases as well as improve malaria diagnosis and treatment abilities for related personnel at all levels of medical institutions. Also we should focus on the Plasmodium check, focus survey and disposal to realize the aim of malaria elimination in Jiangsu Province in time.
