It is a truism that population mobility facilitates the spread of infectious disease.1 Infected individuals will carry the infection with them when they move and, if infectious, may infect others, spreading the infection from one area to another. The spread of Sudden Acute Respiratory Syndrome (SARS) is the most recent high profile example, and the development of the human immunodeficiency virus (HIV) pandemic has been no exception.
We also expect a priori that as an epidemic spreads spatially through a population, mobility between areas of higher and lower prevalence will be found to be a risk factor
