在脊髓灰质炎流行期间,典型病例诊断不难,发热的婴幼儿有轻度的神经根牵引痛和颈背强直,感觉过敏,若同时有嗜睡、多汗、一过性尿潴留等症状,应疑及本病。如出现肌肉弛缓性瘫痪、腱反射消失而感觉存在,就应考虑脊髓灰质炎。但平时散发病例,在前驱期易误诊为上感,其瘫痪前期与柯萨奇和ECHO、腮腺炎病毒、腺病毒、淋巴脉络丛脑膜炎病毒等引起的无菌性脑膜炎,在临床症状体征、脑脊液改变方面都相似,很难区别。尤其是无瘫痪型更不易诊断。
During the epidemic of poliomyelitis, the diagnosis of typical cases is not difficult, fever, infants and young children have mild nerve root pain and neck stiffness, sensory allergies, if both sleepiness, hyperhidrosis, transient urinary retention and other symptoms should Suspected of the disease.

But usually sporadic cases, easily misdiagnosed as a sense of the precursor period, the paralysis of the early and Coxsackie and ECHO, mumps virus, adenovirus, lymphatic choriomeningitis virus caused by aseptic meningitis, clinical signs and symptoms , Cerebrospinal fluid changes are similar, it is difficult to distinguish. In particular, paralysis is more difficult to diagnose.
