This photograph showed a rash on the arm of a Marburg patient who was treated in Johannesburg, South Africa in 1975. Notice how the skin blanches after pressure is applied (arrow). This type of maculopapular rash, which can appear on Marburg patients around the fifth day after the onset of symptoms, usually may be found on the patient’s chest, back and stomach. This patient’s skin blanched under pressure, which is a common characteristic of a Marburg virus rash.
