  1. Work and play: Disease spread, social behaviour and data collection in schools Dr Jenny Gage, Dr Andrew Conlan, Dr Ken Eames

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

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

  4. Even within a small school, there’s a lot of spatial structure… Class Class Class Travel Playground Dining hall Class Class Class … but how do different parts interact?

  5. Structure of Contacts: Building Networks Who mixes with whom?

  6. Drawing contact networks At our last research group meeting, we asked everyone to choose any two people in the room. We’ll now plot this table as a contact network.

  7. Drawing contact networks Who is named most frequently? Julia

  8. Drawing contact networks It helps to put people with a lot of links in the centre. It’s also a good idea to work systematically. Julia

  9. Drawing contact networks Who is named second most frequently? Julia

  10. Drawing contact networks Ken Julia

  11. Drawing contact networks Who is named third most frequently? Julia

  12. Drawing contact networks Ken Andrew Julia Josh Alicia

  13. Drawing contact networks Who is named fourth most frequently? Julia

  14. Drawing contact networks Ken Johann Andrew Julia Tom Josh Alicia

  15. Drawing contact networks We’ve got all the contacts now - is anyone missing? Julia

  16. Drawing contact networks Ken Johann Andrew Julia Roberto Tom Josh Alicia

  17. Drawing contact networks Ken Now we add the links for each person. Johann Andrew Julia Roberto Tom Josh Alicia

  18. Drawing contact networks Ken Now we add the links for each person. Johann Andrew Julia Roberto Tom Josh Alicia

  19. Drawing contact networks Ken Now we add the links for each person. Johann Andrew Julia Roberto Tom Josh Alicia

  20. Drawing contact networks Ken Now we add the links for each person. Johann Andrew Julia Roberto Tom Josh Alicia

  21. Drawing contact networks Andrew and Josh have already named Julia, so these become MUTUAL LINKS. Ken Johann Andrew Julia Roberto Tom Josh Alicia

  22. Drawing contact networks Andrew and Alicia have already named Ken, so these become MUTUAL LINKS. Ken Johann Andrew Julia Roberto Tom Josh Alicia

  23. Drawing contact networks Ken Johann Andrew Julia Roberto Tom Josh Alicia

  24. Drawing contact networks Johann has already named Tom, so this becomes a MUTUAL LINK. Ken Johann Andrew Julia Roberto Tom Josh Alicia

  25. Drawing contact networks Ken Johann Andrew Tom Julia Roberto The network is now complete, but moving Tom will make it easier to see what’s going on. Josh Alicia

  26. Drawing contact networks Ken Roberto Andrew Tom Johann Julia We could usefully move Roberto also. Josh Alicia

  27. Drawing contact networks Ken Roberto Tom Andrew Johann Julia Alicia Josh … and Andrew.
