弓形虫病是儿科常见的人畜共患的寄生虫病。先天性感染以眼、中枢神经系统、肺脏、肝脏最常受累。免疫活性完全的儿童其原发感染大多数为无症状性,部分感染可引起淋巴结大;免疫受损儿童的感染可累及所有器官。虽然早期、有效的治疗可减少先天性和免疫受损儿童感染的病死率及致畸率,但积极预防弓形虫感染胜过治疗。 Toxoplasmosis is a common zoonotic parasitic disease in pediatrics. Congenital infection of the eye, the central nervous system, lungs, liver most commonly involved. Most immunocompromised children whose primary infection is asymptomatic, partially infected can cause lymph node enlargement; immunocompromised children infected can affect all organs. Although early and effective treatment reduces the mortality and teratogenicity of infections in congenital and immunocompromised children, it is better to prevent Toxoplasma infection than cure.
