Abstract
Objective To investigate the characteristics and trends of malaria cases in Lishui City,Zhejiang Province from 2012 to 2023,so as to provide a basis for improving malaria prevention and control measures.Methods Case da-ta of malaria in Lishui City from 2012 to 2023 were collected from the Parasitic Disease Control Information Manage-ment System of the National Information System for Disease Control and Prevention in China.The parasite species,source of infection,temporal distribution,population distribution,geographical distribution,and clinical diagnosis and treatment of the cases were descriptively analyzed.Results A total of 169 malaria cases were reported in Lishui City from 2012 to 2023,and P.falciparum malaria was the main type,accounting for 79.88%(135 cases).The positive rate of Plasmodium detection was 3.30‰(169/51 212),the highest was 5.41‰(18/3 327)in 2017,and the lowest was 0.38‰(1/2 632)in 2021.Malaria cases were reported in every month from 2012 to 2023,with 91 cases(53.85%)re-ported from May to October.There were 168 imported cases,of which 163(96.45%)originated from Africa.There were 127 male cases(75.15%),and the majority of cases were aged 20 to 49 years,with 138 cases accounting for 81.65%.The majority of the occupation was overseas labor export workers,with 164 cases accounting for 97.04%.A total of 161 cases(95.27%)were registered residents of Lishui City,and cases were reported from all nine counties(cities,dis-tricts),with Qingtian County and Liandu District having the higher numbers of 98 and 41 cases,respectively.The medi-an interval from onset to hospital visit for malaria cases was 2.00(interquartile range,4.00)days,and the median inter-val from hospital visit to diagnosis was 0(interquartile range,1.00)day.The diagnostic rate of first-diagnosed malaria cas-es in municipal and county medical institutions was 95.90%(117/122)and 91.49%(43/47),respectively,with no statistical significance(P>0.05).Conclusions The P.falciparum malaria was the predominant type in Lishui City from 2012 to 2023,with the majority of cases being imported.Male overseas labor export personnel aged 20 to<50 were the key demo-graphic.
