2012-2015年上海市實驗室瘧疾檢測能力比較分析
[Abstract]:Aim to compare the application of Plasmodium malaria microscopic examination, rapid detection of antigen (RDT) and nucleic acid detection of (PCR) in Shanghai Municipal and Regional Centers for Disease Control and Prevention (CDC), and to analyze the laboratory detection capability of malaria in Shanghai. Methods the blood smears of malaria cases and suspected malaria cases in Shanghai from 2012 to 2015 were collected from the Center for Disease Control and Control of Shanghai. The whole blood samples, the record of case review confirmation and the epidemic situation of malaria cases in Shanghai were collected. The results were compared and analyzed. Results from 2012 to 2015, 212 samples were sent to every district and county in Shanghai. Jinshan District was the most (41.98%), and the third-level hospital was the largest (82.07%). From January to October, the number of samples sent for examination increased gradually. A total of 167 (78.77%) confirmed malaria samples and 45 negative (21.23%) samples were detected simultaneously by RDT and PCR methods, and all blood samples were examined by microscope, and the results showed that the total number of confirmed malaria samples was 78.77% (78.7%) and 21.23% (45 / 212) respectively. The laboratory at county level detected 153 positive samples (72.17%) by microscope and domestic RDT, of which 41 (19.34%) were positive and 53 (25.00%) were negative. 6 cases (2.83%) were not detected. It was reported that the coincidence rate of microscopic examination was 78.16% in hospitals and CDC centers in districts and counties, 93.20% in CDC centers in districts and counties and in CDC centers in cities and counties. The utilization rate of RDT was 73.58%, and the coincidence rate between domestic RDT and imported RDT in CDC was 93.59%. According to the test results of CDC, 37 cases of malaria were misjudged by laboratory at district and county level. 99.37% of confirmed malaria cases were imported abroad, including Africa (85.44%), Asia (13.92%) and the Americas (0.63%). Conclusion the surveillance work after malaria elimination in Shanghai should be carried out in combination with multiple detection methods and integrated resources.
