[Epidemiological characteristics of malaria prevalence in Xiaoshan District, Hangzhou City, 2012-2014]

To understand the malaria epidemic situation and characteristics in Xiaoshan District, 2010-2014, so as to provide the evidence for formulating effective malaria elimination strategies and measures.

The reported malaria cases from the Internet Reporting System and the epidemiological data of malaria in Xiaoshan District were collected and analyzed statistically with Excel 2003.

From 2010 to 2014, 25 malaria patients were reported, and the annual incidences were in the range of 0.09/100 000-0.38/100 000. All the cases were confirmed by laboratory examinations. Among these cases, 12 (48.00%) were vivax malaria cases and 13 (52.00%) were falciparum malaria cases. There was no death. These patients were mainly young people who were workers or businessmen overseas. There were 17 (68.00%) abroad-imported cases and 8 (32.00%) domestic-mobile cases, but no local malaria cases.

Malaria incidence rate continues at a lower level in Xiaoshan District. Since starting the action of malaria elimination, the source of infection has turned from domestic-mobile cases to abroad-imported cases. Therefore, in the future, we should enhance the prevention and control measures to reduce the risk of overseas imported malaria.
