[Epidemiological analysis of malaria prevalence in Jiangsu Province in 2017].

Objective: To understand the malaria epidemic situation and characteristics in Jiangsu Province in 2017, so as to provide the evidence for formulating the targeted strategy of malaria elimination.

Methods: The data of malaria cases in Jiangsu Province in 2016 were collected from China's Routine Diseases Surveillance Information System (CRDSIS).

Results: Totally, 239 imported malaria cases were reported in Jiangsu Province in 2017, and the cases decreased by 22.

[Results analysis of Jiangsu Provincial Malaria Diagnostic Reference Laboratory in 2017].

Objective: To analyze the results of samples testing of Jiangsu Provincial Malaria Diagnostic Reference Laboratory in 2017, so as to provide the evidence for improving the malaria diagnostic performance in this province.

Methods: The samples of reported malaria cases in Jiangsu were collected by the provincial reference laboratory (PRL) in 2017. The microscopy and nucleic acid test were performed to confirm the infection of species of each case, while antigen tests (rapid diagnostic test, RDT) were performed as well.

[Challenges for maintaining achievements of malaria elimination in Jiangsu Province, China].

Objective: To analyze the situation of malaria elimination, identify the current main challenges and difficulties of maintaining the achievements of malaria elimination, and find out feasible solutions in Jiangsu Province.

Methods: Through randomized grouping, the subject discussion and questionnaires were conducted by malaria control staffs from centers for diseases control and prevention of 13 cities of Jiangsu Province and Jiangsu Institute of Parasitic Diseases. The basic characteristics of participants and the effect of the discussion were analyzed through questionnaires.

[Construction and application of malaria biobank].

Objective: To establish a systemized malaria biobank with well-rounded epidemiologic data and a computer-aid management system, thus to provide qualified sources for malaria elimination and human malaria research.

Methods: The malaria biobank was based on the platform of Jiangsu Institute of Parasitic Diseases. The blood smear samples, dried blood samples, whole blood samples and parasite strains isolated from patients (from both local and imported cases) were collected since 2011 according to a standardized operational procedure.

[Vector surveillance in Jiangsu Province during the stage of malaria elimination].

Objective: To analyze the vector surveillance results during the stage of malaria elimination, so as to provide the evidence for assessing the local transmission risk of imported malaria and carrying out the surveillance work after malaria elimination in Jiangsu Province.

Methods: From 2011 to 2017, the mosquito population was monitored and human biting rates were calculated by the half overnight human baiting trapping method and overnight lamp trapping method in 7 surveillance sites from June to October. The insecticide resistance level was tested by the force contact method recommended by WHO.
