Abstract: 【Abstract】  Imported falciparum malaria data of Henan Province in 2005-2009 were collected and statistically analyzed by using Microsoft Office Excel 2003. A total of 84 imported falciparum malaria cases with one death were reported during 2005-2009. The ratio of males to females was 20 ∶ 1（80/4）. The average age was （34±11） years old. Seventy-five patients returned from Africa, occupying 89.3%. The number of annual cases reported in 2008 （24 cases） and 2009 （32 cases） was higher than that in 2005-2007（9-10 cases）. The top three high-risk populations were farmers （34 cases）, workers （17 cases） and the cadre （13 cases）, accounted for 76.2% of all cases. The cases were reported every month, of which 37 cases（44.0%） were reported in June and July. All cases had a history of prior residence in falciparum malaria endemic area, and the initial symptom was fever. The average interval from symptom appearing to diagnosis was （5.9 ± 8.6） d, only 21.4% （18/84） of the patients was diagnosed within 24 h. There were 72 laboratory-confirmed cases（85.7%）. Seventeen cases （22.1%） were reported by county level medical treatment units. A total of 83 cases recovered with the treatment of artemisinin-based combination drugs. One case died with serious cerebral malaria. Effective measures should be carried to control the increasing trend of imported falciparum malaria.
