Is Wearing a Mask Outside Necessary?

As more Americans are vaccinated, questions about mask-wearing have become common.
Growing evidence suggests that outside coronavirus transmission is significantly less likely to occur than inside transmission.
Regardless, mask-wearing
remains controversial, even
for those who are vaccinated.
Experts say that the answer about whether or not to wear a mask around others outdoors comes down to a "two-out-of-three rule."
For those who are vaccinated, the rule breaks down to a combination of three simple conditions: outdoors, masked and distanced.
Indoors and distanced = wear a mask.
Outdoors and not distanced = wear a mask.
Outdoors and distanced = no mask is necessary.
Basically, for those who are vaccinated, being outdoors and socially distanced equates to a chance to go maskless.
