[A retrospective analysis on the diagnosis and reporting of imported malaria in Jiangxi Province during 2012-2015].

Objective: To provide scientific basis for malaria surveillance in the elimination phase by retrospectively analyzing the diagnosis and reporting of imported malaria in Jiangxi Province.

Methods: Data on malaria endemic situation and individual cases during 2012-2015 were collected through the National Information Management System for Infectious Diseases and the Report and Information Management System for Parasitic Diseases Control and Prevention. Detailed information on primary medical units, laboratory testing units, reporting units, diagnostic methods, time from onset to first medical visit, time from first medical visit to reporting, and time from onset to reporting was analyzed with the descriptive analysis method.

Results: A total of 207 malaria cases were reported during 2012-2015 in Jiangxi, all were imported cases and 96.62%(200/207) were diagnosed with laboratory tests. The main primary medical units were found to be county-level (29.95%, 62/207) and prefecture-level (25.60%, 53/207) medical institutions, while the main laboratory testing units were prefecture-level medical institutions(35.27%,73/207) and county-level CDCs (20.29%, 42/207). There was a significant difference in the proportion of different laboratory testing units among the years(P < 0.05). The median time from onset to first medical visit was 1 d (0-149 d), from first medical visit to reporting was 3 d (0-144 d), and from onset to reporting was 5 d (0-149 d).

Conclusions: The first visit and the laboratory testing of malaria cases mainly occur in the prefecture-level and county-level medical institutions.
