Preventing the next pandemic
Seven major anthropogenic
drivers of zoonotic disease
emergence
1. Increasing demand for
animal protein
2. Unsustainable agricultural
intensification
3. Increased use and
exploitation of wildlife
4. Unsustainable utilization
of natural resources
5. Travel and transportation
6. Changes in food supply
chains
7. Climate change

At least one billion people on the planet are also impacted because of
endemic livestock diseases
Over 1 billion people; two-thirds of rural livestock keepers are women; 40% agricultural GDP
Loss of animals; or their productivity impacts on multiple livelihood dimensions

Pandemics and endemics: One Health approach needed
Prepare – detect – prevent – respond

8
Prepare: invest in One Health
Detect: early detection

9
Respond: the need for biological sciences in pandemics
 Understand viral populations:
 Smart molecular surveillance
 Whole genome sequencing
 Understand the process of infection:
 Molecular interactions that
permit host species jumps
 Identify potential animal
reservoirs of pandemics
 Develop universal vaccines to viral
families with pandemic potential to
control animal reservoirs

Respond: Minimize food-borne risks and hazards
Improve not prohibit
Enabling (regulatory)
environment
Training and simple
technology
Incentives
Fresh food markets all around the
world: 80% of the food for most people

11
Respond: coordination and action at every level

From
grassroots…..to
ministries…to
regional and global

Key messages
Human-animal-environment health are inextricably linked
A One Health approach is essential
Strong health systems mean coordination and action for:
- Preparedness
- Detection
- Prevention
- Response
Beware of reactions that don’t consider trade-offs:
- E.g. improve don’t close wet markets
Science has a key role, and must connect across all other stakeholders
