|Description:||This image depicts a close-up of the skin revealing the morphology exhibited by a number of lesions that had been caused by the Orf virus. These were the “crust”-type Orf virus lesion. See PHIL 15719, to see the appearance of what is referred to as a “vesicular” type of Orf lesion.|
The Orf virus is a pathogen common to sheep and goats, but can at times be transmitted to humans, in which case the virus is known as being “zoonotic”. When a human being becomes infected, the symptoms are mainly confined to the skin, and consist of “weeping” nodules manifesting upon the dorsum, or back of the hands, and which heal in approximately thirty-five days in a spontaneous fashion.
