SUMMARY:How to measure social mixing? - Timo Smieszek\, Public Health Engl
 and and Imperial College
DTSTART:20140627T150000Z

CONTACT:Dr P Klepac
DESCRIPTION:Various methods\, mostly contact surveys and sensor-based appr
 oaches\, have been used to measure social mixing for elucidating infectiou
 s disease transmission dynamics of respiratory infections. Large and very 
 detailed contact datasets have been obtained using these methods\, e.g.\, 
 within the POLYMOD and SocioPatterns projects\, and have been used to gain
  insights into infection transmission. Despite their wide use\, systematic
  comparisons of these methods as well as research on measurement errors an
 d biases are rare.\n \n\nIn my seminar\, I will discuss how ‘potentially
  contagious contact’ has been defined for various diseases and methods. 
 I will contrast different data collection methods\, in particular survey a
 nd sensor methods\, and elucidate their strengths and weaknesses. Next\, I
  will report how contact data obtained from surveys differ from data measu
 red by sensors. Finally\, I will shed light on the problem of survey under
 reporting and discuss which kind of contact is more likely to remain unrep
 orted and by whom.
