Babesiosis is a disease caused by parasites that infect red blood cells; in infants it can be acquired from tick bites, blood transfusions, or congenitally via vertical transmission. It can present with thrombocytopenia, fevers, and parasitemia.
A case of vertically transmitted babesiosis in an infant is described. Thrombocytopenia and parasitemia > 4% developed in this well-appearing infant. The diagnosis was made by history and blood smear in both infant and mother, and the patient recovered fully with oral antibiotics. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Congenital babesiosis has been reported infrequently in the literature and is reviewed here. It is important to consider congenital tick-borne illness in endemic areas as a cause for febrile thrombocytopenia in neonates.
巴贝斯虫病是一种由感染红细胞的寄生虫引起的疾病；在婴儿中，它可通过蜱叮咬、输血或经垂直传播先天性获得。它可表现为血小板减少、发热和寄生虫血症。
描述了一例婴儿垂直传播的巴贝斯虫病病例。该外观良好的婴儿出现了血小板减少和寄生虫血症>4%。通过婴儿和母亲的病史及血涂片做出诊断，患者口服抗生素后完全康复。急诊医生为何应了解此情况？：先天性巴贝斯虫病在文献中报道较少，在此进行综述。在流行地区，将先天性蜱传播疾病视为新生儿发热性血小板减少的病因很重要。
