Work and play: Disease spread, social behaviour

and data collection in schools

Dr Jenny Gage, Dr Andrew Conlan, Dr Ken Eames

Metapopulation models• Complicated word for something familiar.• Population patches: lots of infection within a patch, less transmission between patches.

• Lots of people close together in the same place.• Many susceptibles - ideal for an epidemic.

Even within a small school, there’s a lot of spatial structure…
