Abstract: Abstract Social epidemics or behaviorally based non-communicable diseases are becoming an increasingly important problem in developed countries including the United States. It is the aim of our paper to propose a previously understudied aspect of the spread of social epidemics, the role of information in both causing and mitigating social epidemics. In this paper, we ask, can information be harmful, contagious, and a causal factor in social epidemics? In the spread of biological epidemics, the causal agents are biological pathogens such as bacteria or viruses. We propose that in the spread of social epidemics, one of the causal agents is harmful information, which is increasing exponentially in the age of the internet. We ground our idea in the concept of the meme and define the concept of an infopathogen as harmful information that can spread or intensify a social epidemic. Second, we ask, what are the best tools to understand the role of information in the spread of social epidemics? The epidemiological triad that includes a host, agents (and vectors), and the environment is extended into a quad by including information agents. The quad includes the role of information technologies as vectors and the impact of the social environment. The “life cycles” of pathogens in biological epidemics and infopathogens in social epidemics are compared, along with mitigations suggested by the epidemiological quad. Challenges to the theory of infopathogens, including the complexities associated with the spread of memes and the role of behavior in the spread of epidemics are discussed. Implications of the theory including the classification of harmfulness, the freedom of speech, and the treatment of infected individuals are also considered. We believe the application of the epidemiological quad provides insights into social epidemics and potential mitigations. Finally, we stress that infopathogens are only part of social epidemic development; susceptible hosts, a favorable environment, and availability of physical agents are all also required.
