Aerosol challenge provides the ability to investigate in-depth mucosal virus exposure, including modeling of airborne transmission from high-consequence viral infection. For filoviruses, in particular Marburg and Ebola viruses, aerosol infection is considered in connection to their potential misuse. Aerosol exposure with filoviruses has been used to study disease progression, pathogenicity, and the efficacy of medical countermeasures. The aim of this protocol is to provide a general outline for aerosol exposure of animals with filoviruses, specifically Marburg virus.
