N2 - During the course of a day an individual typically mixes with different groupsof individuals. Epidemic models incorporating population structure withindividuals being able to infect different groups of individuals have receivedextensive attention in the literature. However, almost exclusively the modelsassume that individuals are able to simultaneously infect members of all groups,whereas in reality individuals will typically only be able to infect members ofany group they currently reside in. In the current work we develop a modelwhere individuals move between a community and their household during thecourse of the day, only infecting within their current group. By defining a novelbranching process approximation with an explicit expression for the probabilitygenerating function of the offspring distribution, we are able to derive theprobability of a major epidemic outbreak.
