１９８７～１９９３年检测了ＡＦＰ病例１４７名，其中属广州市本地患者８６例。通过病毒分离鉴定，血清学检查和病毒抗原表位分析揭示了广州地区ＡＦＰ的病原学具有四个特点：（１）除了ＰＶ＿（１－３）型之外，还有ＣｏｘＡ９，ＣｏｘＢ３、５，ＥＣＨＯ７、１２、１３、１８，以及一些未定型的非ＰＶ肠道病毒；（２）脊灰病例与非脊灰病例之比下降（０．８７：１）；（３）从广州市脊灰病例所分离的病毒型别及抗原性质已由ＰＶ＿１型野病毒为主，动态地转变为ＰＶ＿２型类疫苗株为主。从１９９２年开始已不能从病人分离到野病毒株；（４）输入脊灰病例已超过本地病例（４７：４０），输入脊灰仍然是以ＰＶ＿１型为主。
From 1987 to 1993, 147 AFP cases were detected, of which 86 were local patients in Guangzhou. Isolation and identification of viruses, serological tests and analysis of epitopes revealed that there are four characteristics of AFP etiology in Guangzhou: (1) In addition to PV_ (1-3), CoxA9, CoxB3,5, ECHO7 , 12,13,18, and some non-typed non-PV enterovirus; (2) the ratio of polio cases to non-polio cases decreased (0.87: 1); (3) The type of virus and antigenic nature of the isolate have been mainly dominated by PV_1 type wild-type virus and dynamically transformed into PV-2 type vaccine strains. No wild-type isolates have been isolated from the patient since 1992; (4) polio cases have been imported more than local cases (47:40), polio inputs are still predominantly PV_1.
