Epidemic situation of imported malaria and diagnostic capabilities of medi-cal institutions in Wuhan City from 2008 to 2017 / 中国血吸虫病防治杂志

ABSTRACT

Objective To understand the epidemiological characteristics of imported malaria and the control and diagnostic capacities of the medical institutions in Wuhan City,so as to offer the evidence for formulating the surveillance and control strat-egies.Methods From 2008 to 2017,the epidemiological data of imported malaria were collected.The information including gender,age,distribution,vocational background,positive rate of fever patients,and time of final diagnosis was analyzed with the descriptive statistic method.The Plasmodium species composition and infection source were analyzed by chi square test.The initial and confirmed diagnosis abilities of medical institutions were analyzed by rank sum test.Results Totally,424 imported malaria cases were reported,including 301 falciparum malaria cases(70.99％).The male population aged 20 to 49 years was the main morbidity group,and the incidence was not related to seasons.For the parasite species,there was a significant differ-ence between African countries and Southeast Asian countries(Χ 2=205.83,P<0.01).Plasmodium ovale and P.malariae were all imported from sub-Saharan Africa.For diagnostic capacities of the medical institutions at different levels,the initial diag-nosis(Z=-3.89,P<0.01)and confirmed diagnosis(Χ2=53.88,P<0.01)were significantly different,respectively.The abili-ty of malaria diagnosis was improved rapidly in the clinical laboratory after 2008 and achieved to 100％in 2010.The detection rate within 24 hours increased to at least 90％and the detection rate within 6 days decreased to 0 in 2016.Conclusions Al-though the medical institutions in Wuhan City have strong ability to treat imported malaria,they are still faced with a serious sit-uation for malaria control and elimination.The capacity building should be strengthened constantly.
