Before revision:  To model more realistic systems , we study how heterogeneity in person-to-person interactions affects the spreading of diseases when two different kinds of disorder are present, each with a particular value of a. This allows two different types of interaction to emerge, such as close (family, coworkers) and distant (neighbors, strangers) contacts. We also develop a strategy for controlling distant contact times , which are easier to alter in practice , so as to reduce the total number of infected individuals.
After revision:  To model more realistic systems , we study the SIR model for disease spreading when both close and distant types of interactions are present. We develop a mitigation strategy that reduces only the time duration of distant contacts , which are easier to alter in practice , so as to reduce the total number of infected individuals.
