由无症状(无症状和无症状)个人产生的感染已被确定为新冠肺炎传播的主要驱动因素。没有症状的个人,不知道他们对他人构成的感染风险,可能会认为自己--并被其他人认为--不存在感染风险。然而,目前使用的许多流行病学模型不包括行为成分,也没有解决风险误解的潜在后果。为了研究行为适应对感知的感染风险的影响,我们使用了一个数学模型,该模型结合了个人的行为决策,基于系统在有限规划范围内的未来状态的投影。我们发现,在没有症状的个体存在的情况下,个体的风险误解可能会增加或减少最终的流行病规模。此外,在行为反应下,无症状感染的影响受到有症状个体行为的调节。最后,我们发现存在一个使最终传染病规模最小化的最优规划范围。
Infections produced by non-symptomatic (pre-symptomatic and asymptomatic) individuals have been identified as major drivers of COVID-19 transmission. Non-symptomatic individuals, unaware of the infection risk they pose to others, may perceive themselves—and be perceived by others—as not presenting a risk of infection. Yet, many epidemiological models currently in use do not include a behavioral component, and do not address the potential consequences of risk misperception. To study the impact of behavioral adaptations to the perceived infection risk, we use a mathematical model that incorporates the behavioral decisions of individuals, based on a projection of the system’s future state over a finite planning horizon. We found that individuals’ risk misperception in the presence of non-symptomatic individuals may increase or reduce the final epidemic size. Moreover, under behavioral response the impact of non-symptomatic infections is modulated by symptomatic individuals’ behavior. Finally, we found that there is an optimal planning horizon that minimizes the final epidemic size.
