RESUMO
OBJECTIVE: To understand the incidence and trend of malaria in Xuzhou City, so as to provide the evidence for formulating the malaria control measures. METHODS: The information of network reported malaria cases and epidemiological data were collected and analyzed statistically in Xuzhou City from 2010-2013. RESULTS: A total of 109 malaria cases were reported by the special report systems and the network report system in Xuzhou City from 2010 to 2013, in which there were 44 cases (40.37%) of vivax malaria, 62 cases (56.88%) of falciparum malaria, 2 cases (1.83%) of quartan malaria, 1 case (0.92%) of ovale malaria. The latter three were all imported from other countries. Totally 93 cases (85.32%) were confirmed by laboratory, and other 16 cases (14.68%) were diagnosed clinically. There was the incidence throughout the year and there were no obvious seasonal characteristics. The positive rate of blood test in the floating population was significantly higher than that of the local residents (Χ2 = 868.23, P < 0.01). CONCLUSION: The malaria endemic situation is in the steady decline period in Xuzhou City. The local infections decrease significantly but the imported falciparum malaria cases increase year by year. Therefore, the management for floating population and fever patients should be strengthened.
