What is duck viral enteritis (duck plague), and what should make you call the vet at once?

Viral infection; a notifiable disease in some jurisdictions. You will see sudden death, diarrhoea and dullness. The direction of management is supportive care with no specific drug; where the disease is suspected, see the reporting obligation in column B. In the source chapter this row belongs to the group needing prompt attention; the actual judgement still rests with the veterinarian case by case, and this text gives no drug names or doses.

What is avian influenza, and what should make you call the vet at once?

Waterfowl are among the natural hosts and may carry the virus without signs or fall acutely ill. You will see anything from no obvious signs to sudden heavy mortality. The direction of management is that this falls under statutory reporting and stamping-out measures. In the source chapter this row belongs to the group needing prompt attention; the actual judgement still rests with the veterinarian case by case, and this text gives no drug names or doses.

What is duck viral hepatitis, and what should make you call the vet at once?

Viral infection, highly fatal in ducklings. You will see sudden death and neurological signs (opisthotonos). The direction of management is supportive care; mortality in ducklings is high. In the source chapter this row belongs to the group needing prompt attention; the actual judgement still rests with the veterinarian case by case, and this text gives no drug names or doses.

Ten common diseases of ducks gathered into one table: duck viral enteritis (duck plague), avian influenza, duck viral hepatitis, botulism (limberneck), coccidiosis, colibacillosis, aspergillosis, ocular／sinus problems (conjunctivitis／sinusitis), salmonellosis, and predator trauma. Each row lists cause, signs, examination, treatment direction and prevention; the treatment column gives categories only, never doses. It suits checking against when something looks wrong and you need to narrow down the direction first, or when taking on new birds.

Ducks｜10 Common Diseases (cause → signs → examination → treatment direction → prevention)

This content is compiled from the disease table for ducks in the backyard poultry chapter of the veterinary animal encyclopedia. The same sign calls for different handling in different species, and copying what is done for another species can be harmful — first confirm which animal you are dealing with.

#	Disease (Chinese／English)	Cause	Signs	Examination	Treatment direction	Prevention
1	Duck viral enteritis (Duck plague)	Viral infection; a notifiable disease in some jurisdictions	Sudden death, diarrhoea, dullness	Pathology／laboratory confirmation	Supportive care, with no specific drug; where the disease is suspected, see the reporting obligation in column B	Vaccination (per the local programme), keeping wild waterfowl away
2	Avian influenza	Waterfowl are among the natural hosts and may carry the virus without signs or fall acutely ill	Anything from no obvious signs to sudden heavy mortality	After reporting to the competent authority, official sampling confirms the diagnosis	This falls under statutory reporting and stamping-out measures	Keeping wild waterfowl away, biosecurity measures
3	Duck viral hepatitis	Viral infection, highly fatal in ducklings	Sudden death, neurological signs (opisthotonos)	Pathological confirmation	Supportive care; mortality in ducklings is high	Vaccination (per the local programme), quarantine of breeding ducks
4	Botulism (limberneck)	Ingestion of botulinum toxin from stagnant／putrid water	Progressive muscular weakness and paralysis (a drooping neck is the classic sign), inability to stand	History (state of the water source), assessment of clinical signs	An emergency; supportive care needs veterinary assessment	Keeping the water source clean, avoiding stagnant, putrefying standing water
5	Coccidiosis	Same as the chicken group	Diarrhoea, dullness	Faecal microscopy	Antiparasitic medication must be prescribed	Environmental hygiene
6	Colibacillosis	Same as the chicken group	Diarrhoea, reduced activity	Bacterial culture	Antibiotics must be prescribed	Environmental hygiene
7	Aspergillosis	Damp, mouldy litter or feed	Laboured breathing, reduced activity	Endoscopy, imaging	Antifungal medication must be prescribed	Keeping litter dry, protecting feed from damp
8	Ocular / sinus problems (conjunctivitis／sinusitis)	Too little water to clean the eyes and nostrils normally	Increased ocular and nasal discharge, swelling	Visual inspection	Veterinary assessment is required and prescription medication may be needed	Providing enough clean water
9	Salmonellosis	Same as the chicken group	Diarrhoea, spread through the flock	Faecal culture	Antibiotics must be prescribed, and a withdrawal period comes into play	Hygiene of the environment and drinking water
10	Predator trauma	Ducks roost on the ground and protection at night is often inadequate	Wounds, birds missing, deaths	Visual inspection	Wound management needs veterinary assessment	Securing the housing properly at night

The 10 rows above are copied cell for cell from the encyclopedia chapter, neither rewritten nor condensed; the treatment column gives categories only, never drug names or doses, and any medication must be prescribed by a veterinarian. The line number and content hash of each row in the source chapter are in the evidence chain at the end.

Limits of this content

This content comes from the backyard poultry chapter of the veterinary encyclopedia (see the evidence chain for the original location and content hash). The sources at the end are the authoritative materials cited by that chapter; the correspondence is at chapter level, which does not mean every sentence is traced sentence by sentence back to a given source. This material is for education and cannot replace diagnosis and prescription by a practising veterinarian; in an emergency, seek veterinary care immediately. This text has not been clinically reviewed by a named veterinarian.
