This virus causes scouring in young calves and is implicated in causing ‘winter dysentery’ in adult cows. ‘Winter dysentery’ is misnamed as dysentery and is rare, but explosive diarrhoea will be seen in virtually the whole herd. There is no treatment or vaccine but recovery is swift. Coronavirus is commonly associated with scouring in calves. It can be confirmed by an ELISA on the faeces. Treatment is symptomatic, as well as using oral antibiotics to help the secondary infections. There is a vaccine for calves which can be given to cows 6 weeks before parturition to boost passive immunity.

There is also a vaccine which can be given orally directly to calves within 6 h of birth.
