评估COVID-19大流行期间零售环境的风险

Assessing Risk in the Retail Environment during the COVID-19 Pandemic

C. Budd, K. Calvert, S. Johnson, S. O. Tickle

摘要:

COVID-19疫情造成前所未有的混乱,尤其是在零售业。如果网上购物不能满足基本需求,或更严格的措施已经放宽,顾客必须亲自前往商店。这自然会引起易感个体(客户或员工)受到感染的风险。必须尽可能降低这种风险,同时保持商店的经济可行性。因此,我们探索并比较了COVID-19在涉及人与人之间互动的不同购物情况下的传播:(i)自由流动的非结构化购物;(ii)结构化购物(例如排队)。我们研究(i)或(ii)中的哪一种可能更适合于最大限度地减少COVID-19在特定商店的传播,但须受商店的几何形状、人口对当地指导方针的遵守情况以及商店组织者可能采取的额外安全措施等限制。我们得出了一系列的结论,如单向的自由移动是更可取的双向购物,服务器的数量应该最大化,只要他们可以很好地保护免受感染。

英文摘要:

The COVID-19 pandemic has caused unprecedented disruption, particularly in retail. Where essential demand cannot be fulfilled online, or where more stringent measures have been relaxed, customers must visit shop premises in person. This naturally gives rise to some risk of susceptible individuals (customers or staff) becoming infected. It is essential to minimise this risk as far as possible while retaining economic viability of the shop. We therefore explore and compare the spread of COVID-19 in different shopping situations involving person-to-person interactions: (i) free-flowing, unstructured shopping; (ii) structured shopping (e.g. a queue). We examine which of (i) or (ii) may be preferable for minimising the spread of COVID-19 in a given shop, subject to constraints such as the geometry of the shop; compliance of the population to local guidelines; and additional safety measures which may be available to the organisers of the shop. We derive a series of conclusions, such as unidirectional free movement being preferable to bidirectional shopping, and that the number of servers should be maximised as long as they can be well protected from infection.
