Khan, K., Clark, C., Freifeld, B.S., et al. (2010). Preparing for Infectious Disease Threats at Mass Gatherings: The Case of the Vancouver 2010 Olympic Winter Games. CMAJ. 182(6).
The authors created a model that integrated data on worldwide patterns of commercial air traffic with data on global surveillance of infectious diseases using Web-based intelligence-gathering tools. This allowed them to combine information on locations from where large numbers of people are expected to travel to attend a mass gathering with reports of infectious disease threats of public health significance.
