Outdoor face masks: is it helpful or an hindrance?

In the indoor settings, wearing masks can help to reduce the risk of getting COVID-19 infection.

But in the outdoor setting, masks may not be very helpful as the risk of getting COVID-19 infection from others, in outdoor settings, is considerably smaller.

Two teams discuss the pros and cons of outdoor mask wearing in a BMJ debate.

Apart from infection prevention, I can see some additional benefits for voluntarily wearing masks in the streets.

The streets of major cities have significant air-pollution. So facial masks can help to reduce inhalation of toxic chemicals.

More and more surveillance street-cameras are now deploying facial-recognition software to deter criminals. But the cameras may also track movements of ordinary law-abiding people for marketing and advertising reasons. So face-masks may also be helpful to those with privacy concerns.
