As a result of recent developments in the biological and biochemical characterization of polioviruses, intratypic differentiation of poliovirus strains has become a powerful epidemiological tool. However, use of this tool should be linked with a better system of nomenclature.It is recommended that future poliovirus isolates should be identified by type, country (or city), strain number, and year of isolation. The system should be applied universally from the time of publication of this Memorandum.
由于脊髓灰质炎病毒在生物学和生物化学特性方面的最新进展，脊髓灰质炎病毒株的型内分化已成为一种强大的流行病学工具。然而，该工具的使用应与一个更好的命名系统相联系。建议未来分离的脊髓灰质炎病毒应按型别、国家（或城市）、毒株编号及分离年份进行鉴定。自本备忘录发布之时起，该系统应普遍适用。
