ONLINE COVER Marburg Virus Therapy in the Picture. Shown is a color-enhanced electron micrograph of Marburg virus, which is a filovirus that is closely related to Ebola virus. Both cause severe and often fatal hemorrhagic fever and, currently, no vaccines or drugs have been approved for human use to treat these devastating infections. Thi et al. report a therapy that protects macaques from Marburg virus over a range of times' from shortly after infection up to 3 days after exposure, when symptoms have already appeared.
