Duck plague
Duck plague (also known as duck viral enteritis) is a worldwide disease caused by duck herpesvirus 1 (anatid herpesvirus 1) of the family "Herpesviridae" that causes acute disease with high mortality rates in flocks of ducks, geese and swans. It is spread both vertically and horizontally—through contaminated water and direct contact. Migratory waterfowl are a major factor in the spread of this disease as they are often asymptomatic carriers of disease. The incubation period is three to seven days. Birds as young as one week old can be infected. DVE is not zoonotic.
