Table 4 Factors that influence contact probabilities within mixing groups

Mixing group	Factors that influence contact probabilities
	Imperial-Pitt (Ferguson, 2006)	UW-LANL (Germann, 2007)
Household	Contact probabilities are constant	Contact probabilities vary with age
Neighborhood	Mixing group is not considered	Contact probabilities vary with age
Workplace	75% percent of all workplace contacts occur within a workgroup of close colleagues and the remaining 25% of contacts occur outside the workgroup. Contact probabilities in both cases are constant.	Contact probabilities are constant
School (pre-school, elementary, middle, high, university)	As in workplace	Contact probabilities are constant
Community places, e.g., churches, banks, supermarkets, afterschool	Contact probability between two members varies according to proximity	Contact probabilities vary with age
