The orf virus belongs to the family parapoxvirus and is commonly seen in sheep, goats, and deer. Transmission to humans is most commonly caused by direct contact with infected animals or fomites. Septic arthritis is a serious orthopaedic condition that requires prompt identification and early medical treatment. Septic arthritis is often precipitated by bacteremia, which allows for hematogenous spread of the bacterial load to the affected joint. Without prompt effective treatment, septic arthritis can lead to significant long-term sequelae and disability.</p><p><strong>Case report: </strong>This case report presents a rare occurrence of methicillin-resistant Staphylococcus aureus septic arthritis of a native hip joint in a 56-year-old Caucasian male, precipitated by Orf virus and subsequent bacteremia.
