The sharing of information is an inherent tendency of human beings that helps in content dissemination as it cascades to the larger networked audience. In this article, we have proposed a novel weighted cumulative measure for discovering influential users in such networked structures. Our method generically combines the impact of multiple structural features of the network, along with local and global information to produce weighted cumulative centrality (WCC) score. Local information internments nodes direct neighborhood influence whereas global information scrutinizes network structure as a whole via propagating shortest paths. To assess the performance of our innovated measure, a benchmark diffusion model is employed as an artificial stochastic model to track the rate of information spread. The resultant outcome is verified on five different networks including scale‐free and random, and real‐world networks, namely, Facebook, BlogCatalog, and Twitter network. Furthermore, a comparative study is conducted to justify the spreading ability of proposed multifeature based WCC against existing single‐feature based approaches using relative performance ratio. Simulation with single and multiple triggering nodes endorse the efficacy of our proposed method over existing counterparts in terms of the coverage rate, thus showing support for early adoption phenomena in proposed WCC to infest a social network.

“…This in turn would increase the utility of our methods for realtime inference during an outbreak. Furthermore, it would also be of interest to demonstrate the utility of our modeling framework in different contexts beyond spatial epidemic models, such as static network diffusion processes (30).…”

Significance Mathematical models of infectious disease transmission continue to play a vital role in understanding, mitigating, and preventing outbreaks. The vast majority of epidemic models in the literature are parametric, meaning that they contain inherent assumptions about how transmission occurs in a population. However, such assumptions can be lacking in appropriate biological or epidemiological justification and in consequence lead to erroneous scientific conclusions and misleading predictions. We propose a flexible Bayesian nonparametric framework that avoids the need to make strict model assumptions about the infection process and enables a far more data-driven modeling approach for inferring the mechanisms governing transmission. We use our methods to enhance our understanding of the transmission mechanisms of the 2001 UK foot and mouth disease outbreak.

Epidemics like Covid-19 and Ebola have impacted people’s lives significantly. The impact of mobility of people across the countries or states in the spread of epidemics has been significant. The spread of disease due to factors local to the population under consideration is termed the endogenous spread. The spread due to external factors like migration, mobility, etc., is called the exogenous spread. In this paper, we introduce the Exo-SIR model, an extension of the popular SIR model and a few variants of the model. The novelty in our model is that it captures both the exogenous and endogenous spread of the virus. First, we present an analytical study. Second, we simulate the Exo-SIR model with and without assuming contact network for the population. Third, we implement the Exo-SIR model on real datasets regarding Covid-19 and Ebola. We found that endogenous infection is influenced by exogenous infection. Furthermore, we found that the Exo-SIR model predicts the peak time better than the SIR model. Hence, the Exo-SIR model would be helpful for governments to plan policy interventions at the time of a pandemic.
