Yeah, I'm worry about how many asymptomatic people who are still running around, infecting others. It's as you said, if everyone wear mask properly, it'll definitely help control the infection. However, mask simply reduce the amount of virus being released into the air, it does not eliminate virus release (unless you have a fully sealed containment unit)
