Recent work has found that the behavior of an individual can be altered when infected by a parasite. Here we explore the question: under what conditions, in principle, can a general parasitic infection control system-wide social behaviors? We analyze fixed points and hysteresis effects under the Master Equation, with transitions between two behaviors given two different subpopulations, healthy vs. parasitically-infected, within a population which is kept fixed overall. The key model choices are: (i) the internal opinion of infected humans may differ from that of the healthy population, (ii) the extent that interaction drives behavioral changes may also differ, and (iii) indirect interactions are most important. We find that the socioconfiguration can be controlled by the parasitically-infected population, under some conditions, even if the healthy population is the majority and of opposite opinion.

寄生虫感染社会行为的滞后效应

最近的研究发现,当被寄生虫感染时,个体的行为会发生改变。这里我们探讨一个问题:一般的寄生虫感染在什么条件下,原则上可以控制全系统的社会行为?我们在主方程下分析不动点和滞后效应,在给定两个不同亚群(健康与寄生虫感染)的情况下,两种行为之间的转换在总体保持固定的种群内。关键的模型选择是:(i) 感染者的内部意见可能与健康人群的内部意见不同,(ii) 交互驱动行为改变的程度也可能不同,以及 (iii) 间接交互最重要。我们发现,在某些条件下,社会结构可以被寄生虫感染的人群控制,
