This chapter provides a theoretical overview of social network theory, given the widespread of social media during the COVID-19 outbreak. It mainly focuses on three social network theories (the social capital and structural halls, the strength of weak ties, and the small-world). It gives insights into how different researchers have examined these theories during the pandemics and how they have been used in exchanging and communicating information during pandemics. In addition, it reviews previous research concerning how epidemic propagation often happens based on these theories.
Granovetter's theory of the "strength of weak ties" (SWT) posits that an individual's social network is comprised of weak and strong ties, but that it is through weak ties that new information and resources are received since strong ties usually possess the same information as the individual. This paper explains how SWT can be specified as a unit theory from its metatheoretical form. . .
