- Abstract
Objective To provide the basis for malaria surveillance to prevent re-transmission after malaria elimination by analyzing the treatment and diagnosis of imported malaria cases in Shaanxi Province during 2015-2019. Methods Data on imported malaria cases in Shannxi Province from 2015 to 2019 were collected and sorted through the National Infectious Diseases Information Reporting Management System (IDIRMS) and the Parasitic Diseases Information Reporting Management System (PDIRMS). The diagnostic methods, primary medical units, laboratory testing institutions and diagnostic timeliness of imported malaria cases were described and analyzed by Chi-square test,Fisher's exact test and rank-sum test. Results A total of 409 imported malaria cases were reported during 2015-2019 in Shaanxi Province, and all of which were diagnosed with laboratory tests. The rate of utilization RDT increased from 48.56%(36 / 74) in 2015 to 82.83%(82 / 99) in 2019. The main primary medical unitswere found to be prefecture level medical (67.97%, 278/409) and county level medical (10.27%, 42/409). There was a significant difference in the upward trend of the correct rate of initial diagnosis of the cases (χ² =15.677, P<0.001). The main laboratory testing institution was prefecture level medical(69.44%, 284/409) while the main reported institution was prefecture level medical (66.99%, 274/409).The median time from onset to diagnosis of malaria cases was 4 days, in which the median time from onset to first visit was 2 day. There was a significant difference in the time from first visit to diagnosis (χ² = 25.627, P<0.001), and the interquartile interval of malaria cases was shortened from the longest 4 days in 2015 to the shortest 1 days in 2019. There was a significant difference in the time from first visit to diagnosis among different species of malaria (χ² = 9.115, P=0.028), and P. malariae cases (7 days) were the longest than the other species malaria cases. Conclusion To strengthen the health education of key population to improve the awareness of medical treatment, continuously improve the diagnostic awareness and capabilities of medical institutions, and to play the role of sentinel hospitals in the surveillance of preventing re-transmission after malaria elimination.
