Stomatitis in sheep caused by orf virus can be confused with lesions of more economically significant diseases, including foot-and-mouth disease, but there is no published account of the sequential development of oral orf lesions in the sheep. This report describes the clinical appearance of such lesions during a natural outbreak of the disease in young lambs. Lesions were seen on the gingiva, the tongue and the dental pad/hard palate, and progressed from small erythematous papules to larger, often coalescing papules that in some cases were ulcerated. Resolution started within seven days and was complete within 22 days. The lambs continued to suck and thrive throughout the infection. Lesions at all stages were proliferative, providing a major differentiating factor between orf and other causes of stomatitis in sheep.
由口疮病毒引起的绵羊口腔炎可能会与更具经济重要性的疾病（包括口蹄疫）的病变相混淆，但目前尚无关于绵羊口腔口疮病变连续发展过程的公开报道。本报告描述了在幼羔自然爆发该病期间此类病变的临床表现。病变见于牙龈、舌头和齿垫/硬腭，从小的红斑丘疹发展为更大的、常融合的丘疹，在某些情况下会发生溃疡。消退在7天内开始，并在22天内完成。在整个感染过程中，羔羊继续吮乳并茁壮成长。各个阶段的病变均为增殖性，这是口疮与绵羊口腔炎其他病因之间的主要鉴别因素。
