A probable case was defined as illness observed in any cattle from these farms that showed clinical signs consistent with a poxvirus related infection: vesicopustular
lesions on the udder and/ or teats of cows or on muzzle and/or tongue of suckling calves, fever, lymphadenopathy, and remission after [approximately equal to]3 weeks.
The cutaneous lesions are vesicopustular
, may be umbilicated, and have a hemorrhagic crust.
In early November 2005, the medical team at the Medecins Sans Frontieres France (MSF-F) hospital in Bentiu, Unity State, Sudan, reported several suspected case-patients with generalized vesicopustular
rash that resembled rash caused by MPXV.
