Work and play: Disease spread, social behaviour and data collection in schools Dr Jenny Gage, Dr Andrew Conlan, Dr Ken Eames Diseases then and now Plague Plague 1918 Flu

Plague 1918 Flu HIV/AIDS Discussion What are the mechanisms by which diseases are transmitted? Microbes

Viruses Bacteria Worms Microbes Viruses Bacteria Worms

Person to person spread Discussion Seasonal flu occurs most winters. We want to understand the process, then we can control it. What causes flu? How is it spread? How can we prevent

its spread? www.google.org/flutrends Virus Molecules Virus Molecules Individuals Social Groups Virus Molecules

Individuals Social Groups Virus Molecules Individuals Populations Activity: The Standing Disease Everyone starts sitting down.

One person stands and is the first case. They pick two still sitting to infect. Those two stand up and each pick two others from those still sitting. The next generation stands up and each pick two more and so on. How many steps did the disease take to infect whole class? If time: try with THREE instead of TWO What if your class was bigger? 1
