The mapping of a whole network to identify central individuals at the risk for exposure is difficult. The researchers proposed an alternative to this would be the monitoring the friends of randomly selected individuals. The friend group evaluation could aid in early detection.

The researcher’s objectivities was to only measure the topological factors. The students whom were part of the friend group were proxies for the subject’s location within unobservable social network. The friends were the social marker for the student social network position and observation of the path of infection were
