“…In recent decades, social networks research has contributed to important gains in knowledge critical to programs designed to decrease the spread of infectious diseases (i.e., hepatitis C virus [HCV], human immunodeficiency virus [HIV], and other sexually transmitted diseases [STIs]) to chronic conditions (i.e., tobacco use and obesity) (Flath et al, 2018; Maddox et al, 2014; Morris, 2004; Rothenberg et al, 1998; Valente & Pitts, 2017; Valente et al, 2004; Williams et al, 2019; Wu et al, 2018). The relational data collected through social network analysis (Tubaro, 2014) are particularly important for epidemiological research, mapping how a virus or infectious diseases spread from one person to another within a particular group (Smith & Christakis, 2008).…”
