Comparison on the ability of diagnosis and treatment of imported malaria before and after malaria elimination in Xuchang,Henan
Objective To comparing the diagnosis and treatment of imported malaria cases before and after malaria elimination in Xuchang and analyze the existing problems so as to provide scientific evidence for strengthening surveillance and preventing the secondary transmission of imported malaria cases.Methods Malaria epidemic and case investigation data were collected through the China Disease Prevention and Control Information System,and then the duration from onset to first time to see doctor,the duration from the first time to see doctor to final diagnosis,and the rate of confirmed diagnosis at the first time to see doctor at all-level healthcare institutions were compared.Results A total of 118 laboratory-confirmed imported malaria cases were reported in Xuchang from 2011 to 2022,including 67 cases before malaria elimination and 51 cases after malaria elimination.Among the 118 cases,malignant malaria accounted for 77.12％.Before and after the elimination of malaria,the median durations from onset to first time so see doctor both were 1 day,and the median duration from first time so see doctor to final diagnosis was 0 day and 1 day,respectively;the proportion of cases who saw doctor within 3 days after onset increased from 80.60％before elimination to 94.12％after elimination(x2=4.516,P＜0.05);the proportion of cases diagnosed within 3 days after onset increased from 53.73％before elimination to 72.55％after elimination(x2=4.346,P＜0.05);the proportion of cases confirmed by city-level and county/district-level hospitals increased from 31.3％before elimination to 62.7％after elimination,(x2=11.541,P＜0.01);the proportion of malaria cases diagnosed and treated locally was significantly higher than that before eliminating malaria(x2=10.529,19.383,P＜0.05).Conclusions After the elimination of malaria,the ability of malaria diagnosis and treatment in city-level and county/district-level hospitals of Xuchang increased significantly compared with that before the elimination of malaria;the proportion of cases diagnosed and treated locally upped a lot;the duration from onset to confirmed diagnosis gradually decreased.However,medical staff at township level and below had poor awareness of malaria prevention and control.In the future,it is necessary to strengthen training on malaria prevention and control knowledge for grassroots medical personnel.
