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
