Figure 1. Maculopapular Rash in Marburg Disease

A nonpruritic maculopapular rash (resembling the rash of measles) may occur in up to 50% of patients infected with the Ebola or Marburg viruses within the first week of illness. The rash is more common in light-colored skin and desquamates on resolution. Reprinted with permission from Thieme (Martini GA, Knauff HG, Schmidt HA, et al.
