Definition of Brunhilde virus
Medically reviewed by Dr. Otari Nergadze, Neurosurgeon | Updated: January 2026
Brunhilde virus: Type 1 poliovirus. Named after a female chimpanzee from which it was first isolated. There are two other strains of poliovirus: Type 2 (known as the Lansing virus) and Type 3 (known as the Leon virus). Immunity to one strain does not provide protection against the other two. All three strains are therefore included in the poliovirus vaccine.
