A warm summer is unlikely to stop transmission of COVID‐19 naturally

Elderly at risk,
Warmth won’t halt the virus’ march,
Policy slows time.

摘要

2019年冠状病毒病(COVID-19)疫情的爆发显示,不同地区的传播率(Rt)存在显著差异。确定影响传播率的因素对于抗击COVID-19来说既紧迫又关键。本文探讨了全球277个地区之间的Rt差异及其潜在的社会经济、人口和环境相关因素。在全球范围内,Rt通常在政策干预启动后约两周开始下降。从政策干预启动日期到Rt开始下降日期之间的滞后期为9到19天,在欧洲和北美的滞后期最长。我们发现,老年人口比例或预期寿命可以解释277个地区中约50%的传播率差异。在传播率拐点(RI)处,65岁以上人口比例每增加1%,传播率增加29.4%(25.2%–34.0%),表明老年人面临的感染风险比年轻人高约2.5倍。空气温度与传播率呈负相关,这主要归因于空气温度与人口因素之间的共线性。我们的模型预测,在排除空气温度与人口因素共线性的影响后,RI对温度的敏感性仅为每摄氏度降低2.7%(-5.2%–0%)。RI的低温度敏感性表明,仅靠温暖的夏季自然减缓COVID-19的传播可能性较低。
