Medical Definition of Leon virus
Leon virus: Type 3 poliovirus. Named after the patient in California from whom this virus was first isolated. There are two other strains of poliovirus: Type 1 (known as the Brunhilde virus) and Type 2 (known as the Lansing virus). Immunity to one strain does not provide protection against the other two. All three strains are therefore included in the poliovirus vaccine.Source: MedTerms™ Medical Dictionary
