In the early days of the urban pandemic, many cities had personal protective equipment (PPE) shortages, which adversely affected urban pandemic governance. Using the COVID-19 strategies employed in Wuhan as the pivotal case study, this study sought to determine effective strategies to optimize city PPE distribution. System dynamics modeling was employed to explore the influence of PPE allocation strategies on pandemic control measures. It was found that the most effective method for controlling a pandemic was to supply PPE in a specific order: medical staff, patients, and out-of-home citizens. Further, prioritizing universal PPE access over adhering to recommended replacement frequencies was found to be more effective in protecting public health. These findings offer vital insights for policy formulation and pandemic preparedness planning to reduce infection rates and fatalities.
在城市疫情初期，许多城市存在个人防护装备（PPE）短缺的情况，这对城市疫情治理产生了不利影响。本研究以武汉采用的新冠疫情防控策略作为关键案例研究，旨在确定优化城市个人防护装备分配的有效策略。采用系统动力学建模来探究个人防护装备分配策略对疫情防控措施的影响。研究发现，控制疫情最有效的方法是以特定顺序供应个人防护装备：医务人员、患者和户外市民。此外，研究发现，优先确保普遍获得个人防护装备而非严格遵循推荐的更换频率，在保护公众健康方面更有效。这些研究结果为政策制定和疫情防范规划提供了重要见解，以降低感染率和死亡率。
