Malaria patients who were admitted to the Department of Infectious Diseases of the Tokyo Metropolitan Bokutoh General Hospital during the past 8 years are reviewed. Cases included 17 patients infected with Plasmodium falciparum (14 Japanese), 13 patients infected with P. vivax (9 Japanese), 3 patients infected with P. ovale (2 Japanese) and 1 Chinese patient with a mixed infection of P. falciparum and P. vivax. About 70% of Japanese patients infected with P. falciparum contracted the disease in Africa, about 90% P. vivax-infected Japanese patients contracted the disease in Asia and all P. ovale-infected patients contracted the disease in Africa. Only 13% of all (17% of Japanese) patients infected with P. falciparum who initially contracted doctors of other Japanese hospitals were correctly diagnosed, but 78% of all (67% of Japanese) patients infected with P. vivax who initially contacted doctors of other Japanese hospitals were correctly diagnosed. At present, malaria is not a rare disease in Tokyo among travelers to or from Africa or Asia.
回顾了过去8年入住东京都墨东综合医院传染病科的疟疾患者情况。病例包括17例感染恶性疟原虫的患者（14例日本人）、13例感染间日疟原虫的患者（9例日本人）、3例感染卵形疟原虫的患者（2例日本人）以及1例同时感染恶性疟原虫和间日疟原虫的中国患者。感染恶性疟原虫的日本患者中约70%在非洲感染该疾病，感染间日疟原虫的日本患者中约90%在亚洲感染该疾病 , 所有感染卵形疟原虫的患者均在非洲感染该疾病。最初就诊于其他日本医院的所有感染恶性疟原虫的患者中（日本患者占17%）只有13%被正确诊断，但最初就诊于其他日本医院的所有感染间日疟原虫的患者中（日本患者占67%）有78%被正确诊断。目前，在东京往来非洲或亚洲的旅行者中，疟疾并非罕见疾病。
