Recently, COVID-19 has attracted a lot of attention of researchers from different fields. Wearing masks is a frequently adopted precautionary measure. In this paper, we investigate the effect of behavior of wearing masks on epidemic dynamics in the context of COVID-19. At each time, every susceptible individual chooses whether to wear a mask or not in the next time step, which depends on an evaluation of the potential costs and perceived risk of infection. When the cost of infection is high, the majority of the population choose to wear masks, where global awareness plays a significant role. However, if the mask source is limited, global awareness may give rise to a negative result. In this case, more mask source should be allocated to the individuals with high risk of infection.

最近，COVID-19 引起了不同领域研究人员的大量关注。戴口罩是一种经常采用的预防措施。在本文中，我们调查了在 COVID-19 的背景下戴口罩的行为对流行病动态的影响。每次，每个易感个体都会选择在下一个时间步是否戴口罩，这取决于对潜在成本和感知感染风险的评估。当感染成本很高时，大多数人会选择戴口罩，这在全球意识中发挥着重要作用。但是，如果面具来源有限，全球意识可能会产生负面结果。在这种情况下，应将更多的口罩来源分配给感染风险高的个体。
