西安地区既往无恶性疟疾的报道。近年来作者在西安地区两所医院陆续发现恶性疟疾18例。18例末梢血均经显微镜检查确认为恶性疟原虫感染,其中2例骨髓片中也发现有恶性疟原虫。18例中17例有明确的疫区生活史,提醒医务工作者,对来自疫区的发烧、头痛、关节痛患者,应疑及本病。 Previous reports of non-malignant malaria in Xi’an. In recent years, the authors successively found 18 cases of falciparum malaria in two hospitals in Xi’an. 18 cases of peripheral blood were confirmed by microscopic examination of Plasmodium falciparum infection, of which 2 cases of bone marrow tablets were also found in Plasmodium falciparum. Of the 18 cases, 17 cases had a definite life history of the infected area, reminding medical workers that they should be suspicious of this disease in patients with fever, headache and joint pain from the infected area.
