A growing number of bunyaviruses are known to cause viral hemorrhagic fever (VHF), a severe febrile illness which can progress to hypovolemic shock and multi-organ failure and is characterized by hematologic abnormalities and vascular leak. At present, there are no approved vaccines or antiviral therapies to effectively prevent or treat VHF caused by pathogenic bunyaviruses. Advances in the modeling of bunyaviral infections have facilitated efforts towards the development of novel post-exposure prophylactic and therapeutic countermeasures, several of which may some day be approved for human use. Here, we review recent progress in animal models of severe bunyaviral infections essential to this mission, as well as promising antivirals and biologicals that are at various stages of the development process.
