The warts are like cauliflower lesions or flat thickened lesions on the neck,head,trunk,teats and penis.These lesions normally appear 1-6 months after infection and not all infected cattle show lesions.
The lesions normally spread from ears to other sites,cattle with ear tags or tatoos are prone to infection with secondary bacteria thus causing wide spread purulent discharges .
Cattle with these lesion are properly examined if presented for slaughter in the abattoir and the skin should be condemned.
