对传染病的信息意识对个人抑制感染扩散的决定具有重要影响。在这项工作中，考虑了一个结合易感-感染-恢复（SIR）和无意识（UA）情况的疫苗接种博弈的新数学框架。改变戴口罩或采取预防疾病的措施，我们考虑的是可能代表自我保护情况的信息传播效应。信息传播本应仅针对一个季节的局部情况，但在一代人的时间内对减少感染具有非常重要的作用。在这一概念中，对于无限和混合良好的人口，不知情和有意识的状态被视为易感、受感染和接种疫苗的个人。此外，还研究了个体基于、策略基于和直接选择三种不同的策略更新规则，并通过全阶段图进行了比较。最后，可以看出信息的传播可以抑制流行病在人群中的传播。(C) 2019 Elsevier Ltd.版权所有。
The information awareness about contagious diseases have an influential effect on an individual's decision to suppress the diffusion of infections. In this work, a new mathematical framework for a vaccination game combined with susceptible-infected-recovered (SIR) and unaware-aware (UA) situation is considered. Altering wearing mask or taking protection against diseases, we consider the information spreading effect that might be represented the situation of self-protection. The information spreading is supposed only for local situation for a season, but has a very significant effect to reduce the infection through a generation. Within this concept, unaware and aware states are taken for susceptible, infected and vaccinated individuals for an infinite and well mixed population. Moreover, three different strategy updating rules concerning whether an individual committing or not vaccination: individual based, strategy based and direct selection are studied to show the comparison by depicting as full phase diagram. Finally, it can be seen that information spreading can subdue the spreading of epidemic within a population. (C) 2019 Elsevier Ltd. All rights reserved.
