Question: what does orf look like in humans?
Answer: In humans, the first sign of orf is a small, red, itchy or painful lump (lesion) that usually appears on the fingers, hands, forearms or face after an incubation period of 3 to 5 days. There may be more than 1 lesion in some cases. The lesion will usually be firm, red or blue in colour, and 2 to 5cm in diameter.
