The answer goes beyond the pathogen itself.
Disease emergence is shaped by the interaction between the infectious agent, the host and the environment, from biological characteristics and human immunity to behaviour, ecosystems and the conditions that allow transmission to occur.
Looking at past pandemics reminds us that preparedness also means understanding these connections before an outbreak begins.
A One Health perspective, recognising the links between human, animal and environmental health, can help us better understand emerging infectious disease risks and strengthen our ability to prepare.
Learn from the past. Prepare for the future.
