๐๐ซฆ๐ What Are the Signs of ORF? ๐๐๐
ORF commonly affects the lips, mouth, and surrounding skin but can also affect the feet (coronary band).
It occurs most commonly in young lambs, but occasionally can affect older sheep causing lesions on the teats and udder of nursing ewes. The virus causes sores to form, which encrust before scabbing over and then falling off. The underlying skin heals without scarring. This cycle takes approximately 4-5 weeks. Lambs lose condition as they are reluctant to feed and it is too painful for ewes with teat lesions to feed suckling lambs. Those with foot lesions will be lame. Skin sores may become infected by opportunistic bacteria, causing secondary infection (eg. strawberry footrot).
