44 VVND Necrosis of cecal tonsil and Peyer’s patches

45 African Swine Fever Reddening of ears and skin (non-specific)

46 African Swine Fever Enlarged dark red or black spleen. Note kidney

47 African Swine Fever Hemorrhagic gastro-hepatic lymph nodes

56 Rinderpest Necrosis of Peyer’s patches

57 Rinderpest Zebra stripe hemorrhages of colonic mucosa

58 Peste des Petits Ruminants Zebra stripe hemorrhages of colonic mucosa - goat

59 Stomatitis-Enteritis Case Definition Ocular Discharge Nasal Discharge And Fever Oral Erosions/Lesions Salivation Corneal Opacity Diarrhea Death Outbreaks of contagious disease exhibiting discharge (ocular and nasal) and any two of the above-mentioned symptoms should be reported as stomatitis-enteritis outbreaks. Note that it is the outbreak that must meet the case definition, not individual animals. The stomatitis-enteritis case definition is used to ensure that all case that could be Rinderpest are investigated
