The relationship between zoonotic disease emergence and animal welfare is bidirectional - welfare failures increase disease risk while pandemic responses harm animal welfare.
Zoonotic disease emergence and animal welfare are deeply interconnected. The high-density, immunosuppressive conditions of intensive livestock farming create evolutionary pressure that can generate more transmissible viral strains. Mass depopulation responses to disease outbreaks - killing millions of animals in response to avian influenza or COVID-19 variants - cause acute welfare emergencies for animals who are not themselves sick. One Health frameworks that reduce disease risk by improving animal welfare and reducing wildlife-livestock-human interfaces represent win-win approaches for both welfare and pandemic prevention.
