Major hubs with far-flung flights are most efficient
An infectious disease that really wants to go global would do well boarding planes at JFK or LAX, according to a new computer simulation that ranks U.S. airports by their potential to kick-start an epidemic.
The simulation could help public health officials decide how and where to allocate resources such as vaccinations in the early days of an outbreak, says Ruben Juanes of MIT, who describes the analysis online July 19 in PLOS ONE.
Many simulations of how epidemics spread focus on the final outcome, such as how many people would ultimately be infected. This new work is mostly concerned with how the location of an initial outbr
