A second case in Sweden of Contagious Ovine Digital Dermatitis (CODD), has during the autumn
2020 been demonstrated in southern Sweden. The first case was detected in Sweden in early 2019. CODD is a painful and difficult-to-treat bacterial infection in sheep. First the infection affects the area along the coronary band, then the infection spreads under the hoof horn and can cause detachment of the hoof capsule. CODD is very difficult to treat and is a major problem for sheep farmers in some countries such as the UK. The cause of the disease is not entirely known but Treponema spp. has often been detected in sheep with CODD and sometimes together with Fusobacterium necrophorum and Dichelobacter nodosus.
