The SI model is not practically applicable, as it doesn’t allow infected users to be recovered. The SIS model addresses this problem [13, 14], and focuses on number of persons infected and number of persons cured as well. Once anyone is infected they may be cured and become susceptible in the future. Figure 1.9 explains the same problem where susceptibility of infection is possible [38]. In social networks once a rumor is received by a user he/she may believe or ignore as they knew fact and can become susceptible in the future.
