In the USA, seasonal tickborne transmission of Babesia microti occurs in the Northeast and upper Midwest. A resident of Texas became infected through a red blood cell transfusion from an asymptomatic local donor who had summered in Massachusetts. The patient's infection was diagnosed by blood smear examination in January, 7 weeks post-transfusion. He died 1 week later from variceal haemorrhage complicated by haemolysis. Premortem patient specimens and archived blood from the donor unit tested positive for B. microti antibodies and DNA. Babesiosis should be included in the differential diagnosis of post-transfusion haemolytic anaemia or thrombocytopenia, regardless of the geographical region or season.
在美国，微小巴贝斯虫的季节性蜱传播发生在东北部和中西部上游地区。一名得克萨斯州居民通过输注来自一名无症状当地献血者的红细胞而感染，该献血者曾在马萨诸塞州度过夏天。患者感染在输血7周后的1月份通过血涂片检查确诊。他在1周后死于静脉曲张出血并发溶血。患者生前标本和供血单位的存档血液检测微小巴贝斯虫抗体和DNA呈阳性。无论地理区域或季节如何，巴贝斯虫病都应列入输血后溶血性贫血或血小板减少症的鉴别诊断中。
