Wildlife Disease Management and Animal Welfare

Wildlife disease outbreaks including rabies, distemper, and myxomatosis cause mass suffering at population scale; management approaches vary widely in their welfare implications.

Key Facts

Myxomatosis killed over 99% of UK rabbits when introduced in the 1950s
Canine distemper killed 20% of the Serengeti's lion population in 1994
Rabies kills thousands of people annually and millions of domestic and wild animals
Wildlife vaccination programmes can control disease without culling
Badger vaccination against bovine tuberculosis has been shown to be effective

Welfare Considerations

Disease outbreaks cause mass welfare harm at population scale. Myxomatosis causes prolonged blindness, swelling, and secondary infection before death over 1-2 weeks — one of the most protracted wildlife disease deaths documented. Distemper causes neurological deterioration and death. Rabies causes progressive neurological disease. Vaccination offers disease control without the welfare costs of disease infection or culling. Habitat management that reduces disease transmission reduces individual welfare harm.

What You Can Do

Support wildlife vaccination programmes for rabies and bovine tuberculosis
Advocate for vaccination-first approaches to wildlife disease management
Report sick wildlife to local wildlife trusts and vets for disease monitoring
Support research into wildlife disease dynamics and vaccination delivery
Engage with badger vaccination programmes as an alternative to culling
