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 high mortality in flocks of ducks. It is spread through contaminated water and direct contact. Migratory waterfowl are a major factor in the spread of this disease. The incubation period is three to seven days.[1] Symptoms include depression, loss of appetite, decreased egg production, nasal discharge, increased thirst, diarrhea, ataxia, and tremors. Most ducks that show symptoms eventually die - mortality may reach 90 percent.[2] Vaccination for duck plague is now routine in the United States.[1]
