Dr Muge Cevik at the University of St Andrews and colleagues argue that
outdoor transmission contributes very little to overall infection rates and
efforts should focus on reducing indoor transmission.


No confirmed sizeable covid-19 clusters or “superspreader” events have been
outdoors-only, they say. While the Sturgis Rally in South Dakota or the Rose
Garden outbreak at the White House are frequently cited as evidence for
outdoor-only superspreading events, these events had sustained and multi-
day indoor components. For instance, epidemiological investigation of Sturgis
Rally found cases linked to restaurants and workplaces.

Given the low risk of transmission outdoors, recommendations or mandates
for outdoor masking may seem arbitrary, affecting people’s trust and
sustained energy to engage in higher yield interventions, such as indoor
mask use or staying home if sick, they write.


What’s more, an outdoor mask requirement “might serve as a disincentive to be outdoors, which could worsen social isolation.”
