Winter Dysentery is a highly contagious GI disorder
that affects housed adult dairy cattle primarily
during winter. Current research indicates that it is
caused by a particular strain of Coronavirus that
attacks the intestinal lining of adult dairy cattle.
This disease is typically spread through fecal-oral
transmission; but viral particles present in respiratory
secretions of affected animals may further enhance
transmission. Winter dysentery can spread
throughout an entire herd within 7 to 10 days. Death
is rare and most animals will recover within a week
