“…The study of epidemics on graphs is an active field of research. An important body of work assumes the underlying graph is known, and focuses on modeling epidemics [19,75,32,16,78,47], detecting whether there is an epidemic [8,9,54,53,51,44,40], finding communities [60,76], localizing the source of the spread [65,66,64,69,72,70,20] or instead obfuscating it [26,28,27], or controlling their spread [43,21,22,34,29,71,77,58]. The inverse problem, recovering the network from epidemic data, has also been extensively studied [56,1,18,59,41,35,33].…”
