6 stages of orf in humans

Related questions
What are the symptoms of orf virus? Infection with orf virus is usually confined to the epidermis (top layer) of the skin. Lesions (one to a few) or nodules will often occur on the fingers, hands, or the forearms. Lesions begin as small papules that will become ulcerative in nature. Orf virus lesions typically progress through six stages each lasting approximately one week.
How do you know if you have ORF? Orf occurs in humans with an occupational or household exposure to the virus via infected animals or fomites. The hands are where 95% of cases occur (see the image below). [ 25] The lesions may be pruritic and are generally painless. If the lesions are painful, then secondary infection should be suspected. [ 26]
What is human ORF? Human orf is a benign infection and its diagnosis can be based on clinical findings to avoid unnecessary expensive testing and invasive treatment. We thank Ms Maya Ginzburg for assistance with editing of the manuscript. Orf, which is well known to veterinarians and farmers, is an infection caused by Parapoxvirus that mainly affects goats and sheep.
How long does ORF take to heal? Lesions occur most commonly on the hands. Orf is frequently seen in ranching communities [ 3, 4] and in those who process the animals for consumption. It typically has a self-limited course with spontaneous resolution in 4-8 weeks after progressing through distinct stages.
