A Reason magazine post <a href="https://reason.com/2021/08/24/oregon-masks-mandate-covid-vaccine-kate-brown/" rel="nofollow">https://reason.com/2021/08/24/oregon-masks-mandate-covid-vac...</a> explains why this is unjustified (the article has links):<p>"At this point in the pandemic, forcing vaccinated people to wear masks outside is an unjustifiable act of overreach on the part of government officials. It's also contrary to existing guidance from the Centers for Disease Control and Prevention (CDC), which holds that masks are generally not necessary in outdoor settings. The CDC does state that people may wish to voluntarily wear masks during particularly crowded outdoor gatherings out of an abundance of caution, but we know that confirmed outdoor superspreader events are so rare as to be practically nonexistent.<p>A recent outbreak at Oregon's Pendleton Whisky Music Fest seems to have spooked local authorities; 66 of the 12,000 attendees later tested positive for COVID-19, according to Oregon Live. However, it's far from clear that the infections occurred during the outdoor portions of the event, and 61 of the 66 infected individuals were unvaccinated. It does not make much sense to require all people to wear masks outdoors when only the unvaccinated are at significant risk of being hospitalized with or dying from COVID-19.<p>..."
