Febrile patients in whom a parasitic etiology is suspected can be classified broadly into two categories for the purpose of diagnostic evaluation based on the presence or absence of accompanying eosinophilia. Generally, the absence of eosinophilia indicates a protozoan etiology while the presence of eosinophilia is associated with tissue-invasive helminthic infections. The history and physical examination often points to a specific diagnosis that can be confirmed by appropriate laboratory tests.
出于诊断评估目的，根据是否伴有嗜酸性粒细胞增多，疑似寄生虫病因的发热患者可大致分为两类。一般来说，无嗜酸性粒细胞增多表明为原生动物病因，而嗜酸性粒细胞增多与组织侵袭性蠕虫感染有关。病史和体格检查往往指向特定诊断，可通过适当的实验室检查加以证实。
