Epidemic Spread on Weighted Networks

Figure 1

Weighting between contacts.

Both the number of contacts that an individual maintains and the weight that (s)he assigns to each contact are relevant for the spread of an infectious agent. Here, each individual has l interaction events that (s)he can distribute among his/her k contacts. On the scale of the transmission network, these are modelled by the joint probability distribution to find an individual with k contacts and l interaction events per time interval.
