  abstract = {{D}isease outbreaks are one of the key threats to great apes and other wildlife. {B}ecause the spread of some pathogens (e.g., respiratory viruses, sexually transmitted diseases, ectoparasites) are mediated by social interactions, there is a growing interest in understanding how social networks predict the chain of pathogen transmission. {I}n this study, we built a party network from wild chimpanzees ({P}an troglodytes), and used agent-based modeling to test: (i) whether individual attributes (sex, age) predict individual centrality (i.e., whether it is more or less socially connected); (ii) whether individual centrality affects an individual's role in the chain of pathogen transmission; and, (iii) whether the basic reproduction





number ({R}0) and infectious period modulate the influence of centrality on pathogen transmission. {W}e show that sex and age predict individual centrality, with older males presenting many (degree centrality) and strong (strength centrality) relationships. {A}s expected, males are more central than females within their network, and their centrality determines their probability of getting infected during simulated outbreaks. {W}e then demonstrate that direct measures of social interaction (strength centrality), as well as eigenvector centrality, strongly predict disease dynamics in the chimpanzee community. {F}inally, we show that this predictive power depends on the pathogen's {R}0 and infectious period: individual centrality was most predictive in simulations with the most transmissible pathogens and long-lasting diseases. {T}hese findings highlight the importance of considering animal social networks when investigating disease outbreaks.},
