对传染病的最佳反应

Optimal Responses to an Infectious Disease

Evangelos Magirou

摘要:

我们分析了一个简单的SIRS流行病学模型的最优控制版本。决策者可以采取政策,以特定的经济成本减少感染者和易感者之间的接触率。疫苗的到来将立即结束这一流行病。总或部分免疫力建模,而接触率可以表现出(用户指定的)季节性。该问题在电子表格环境中得到解决。一个合理的参数选择导致最优的政策是相似的,不同的国家遵循。如果有充足的卫生设施,依靠最终达到高免疫水平的温和反应是最佳的。另一方面,有限的医疗保健设施导致严格的封锁,而适度的设施则允许曲线平坦化。

英文摘要:

We analyze an optimal control version of a simple SIRS epidemiology model. The policy maker can adopt policies to diminish the contact rate between infected and susceptible individuals, at a specific economic cost. The arrival of a vaccine will immediately end the epidemic. Total or partial immunity is modeled, while the contact rate can exhibit a (user specified) seasonality. The problem is solved in a spreadsheet environment. A reasonable parameter selection leads to optimal policies which are similar to those followed by different countries. A mild response relying on eventually reaching a high immunity level is optimal if ample health facilities are available. On the other hand limited health care facilities lead to strict lock downs while moderate ones allow a flattening of the curve approach.
