Rift Valley Fever Virus Infection Causes Acute Encephalitis in the Ferret

ABSTRACT Rift Valley fever virus (RVFV) is a pathogen of both humans and livestock in Africa and the Middle East. Severe human disease is associated with hepatitis and/or encephalitis. Current pathogenesis studies rely on rodents and nonhuman primates, which have advantages and disadvantages. We eva...
