What is the definition of an emerging virus
Infections that have:
a) newly appeared in a population
b) increasing the incidence
c) geographic range

What are the drivers of emerging infectious diseases (6)
- Global warming/climate change
- Biological impoverishment
- Habitat fragmentation
- Increasing toxification
- Global movement of people and other living organisms
- Have worked synergistically to diminish ecosystem function
