OBJECTIVE

To analyze the prevalent characteristics of malaria in Jiangsu Province in 2009, so as to provide the reference for making effective measures of malaria control.

METHODS

The reported cases and epidemiological data of malaria in Jiangsu Province were analyzed statistically and described.

RESULTS

A total of 389 malaria cases were reported with an incidence rate of 0.05/10 000 in 2009, 41.77% lower than that in 2008. There were reported malaria cases in all thirteen cities, and 44.73% of all the cases were from Xuzhou, Suqian, and Huai'an. There were 192 local malaria infectors with Plasmodium vivax (P.v) in Jiangsu Province. Majority of the local malaria infectors (73.44%) distributed in Xuzhou, Suqian, and Huai'an City. There were 96 imported infectors of P.v, mainly spreading over the south part of Jiangsu Province with a high percentage of migrant workers. There were 101 imported infectors of Plasmodium falciparum (P. f), 71.19% higher than that in 2008, mainly spreading in the central and north part of Jiangsu Province with a high percentage of workers who worked abroad.

CONCLUSIONS

The results show a decreased trend of malaria incidence in Jiangsu Province, however, the malaria situation in north part to the Huai River is still instable, and there are increasing imported cases of P. f as well. It is necessary to formulate the policy and measures to strengthen malaria control in target areas, especially the monitoring and management of workers who have once worked abroad.
