肠道病毒感染被认为可能是病毒感染后疲劳综合征(PVFS)的病因,因调查发现患者有高效价的柯萨奇B组病毒抗体。然而许多学者认为PVFS不是肠道病毒持续感染所致,而是病毒原发感染后的一种功能障碍后遗症。由于已从皮肌炎、多发性肌炎、慢性心肌炎等病人的肌活检标本中检测到柯萨奇B组病毒的核酸序列,从而证实肠道病毒可引起持续感染。 Enteroviral infection is thought to be the cause of Post-Viral Fatigue Syndrome (PVFS) because of the high titer of coxsackie B virus antibodies found in patients. However, many scholars believe that PVFS is not caused by persistent infection with enteroviruses, but rather a sequelae of dysfunction after the primary virus infection. Since the nucleic acid sequence of coxsackie B virus was detected from muscle biopsy specimens of patients with dermatomyositis, polymyositis and chronic myocarditis, it was confirmed that enterovirus causes persistent infection.
