Mask wearing compositioon the public, particularly outdoors, remains bet. But should masks be worn outside, in some circumstances, to help reduce covid virus transmission - or should efforts focus on reducing indoor transmission where risks are greater? Experts debate the issue in The BMJ today. Babak Javid at the University of California San Francisco and colleagues acknowledge that the risk of covid virus transmission is far greater indoors than outdoors.

Nor do they what best describes the composition of human blood policies that mandate masking outdoors when someone is alone or only with members of one household. But they argue that wearing masks outdoors, particularly at large outdoor gatherings with prolonged close interactions, should be normalised because it may reduce virus transmission and encourage mask wearing indoors, where risks are greater. They say fears of increased transmission after mass protests in support of the Black Lives Matter movement were not realised, whereas the mass outdoor Sturgis Motorcycle Rally in South Dakota, USA, is thought to have been the trigger for a huge superspreading-type event.

One proposed reason for these differences is that the Sturgis Rally was associated with lower short life lesson quotes about relationships with measures such as mask wearing is y=7-3x a linear function physical distancing that are associated with decreased transmission risk, they explain.

They also point to data from the US and Germany showing that regions with public mask mandates have had a lower impact from the virus, while countries with early adoption of face coverings for the public also achieved an earlier acceptance of a social norm during the pandemic. But 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.

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. Equity concerns are also vital, they add, because people who have access to back gardens or can afford private transport to less population dense areas can enjoy the outdoors unmasked, while many others without such cescribes or resources cannot enjoy fresh air or exercise unmasked in settings where mask use is universally mandated outdoors.

They believe the public should be informed about the evolving scientific understanding of transmission mechanisms and should be encouraged to be most vigilant in indoor settings, while noting that prolonged and close contact outdoors may pose a risk. The World Health Organization is currently of the opinion that viral transmission by aerosols, while possible for covid, is not the main route by which SARS-CoV-2 spreads.
