title: The effect of mixing events on the dynamics of pH1N1 outbreaks at small residential colleges.
abstract: OBJECTIVE
  The authors examine the dynamics and the impact of all-campus events on pH1N1 spread at Bates College in fall 2009, with comparisons to 3 other campuses.
  
  
  METHODS
  Students (N = 285) presented or called in to the Bates Health Center with symptoms consistent with influenza-like illness.
  
  
  METHODS
  Health Center staff at Bates collected data on the outbreak; data from other colleges are from Web sites and journal articles. Data were analyzed using a mathematical model for influenza.
  
  
  RESULTS
  Bates held 2 vaccine clinics mid-outbreak. The data are consistent with the hypothesis that the vaccine clinics may have altered routine student interactions, facilitating transmission of pH1N1 among students who otherwise might not have encountered each other.
  
  
  CONCLUSIONS
  The vaccine clinics, held when vaccine became available, were too late to halt transmission. The disruptions to campus rhythms due to the vaccine clinics may instead have contributed to pH1N1 spread.
