Welfare of Animals in Zoonotic Disease Research

Research on emerging infectious diseases requires animal models whose welfare must be balanced against the urgent public health need for zoonotic disease understanding.

Key Facts

COVID-19 research used ferrets, hamsters, and non-human primates as models
Bat coronaviruses research involves capture of wild bats and laboratory maintenance
Influenza research uses ferrets which show respiratory symptoms analogous to human infection
SARS research in the 2000s raised concerns about laboratory-acquired infection risk
High-biosafety-level facilities present unique welfare challenges from restricted access and monitoring

Welfare Considerations

Zoonotic disease research welfare is complicated by the urgency of emerging outbreaks and the biosafety constraints that limit access to housed animals. Research conducted at high containment levels has reduced welfare oversight because fewer personnel can enter animal areas. Animals in high-containment disease research receive less socialization, enrichment, and welfare assessment than equivalent animals in standard laboratories. The welfare cost of urgent outbreak research is real and must be planned for rather than assumed away.

What You Can Do

Support development of organoid and in vitro disease models that reduce animal use in outbreak research
Advocate for welfare assessment requirements that apply even in high-biosafety-level research contexts
Follow biosafety and animal welfare intersection policy developments from research regulatory bodies
Engage with public health organizations about the animal welfare dimension of pandemic preparedness
