It looks like the CDC is reconsidering the advice to not wear masks in public:

The goal isn't to prevent the wearer from getting COVID-19. Rather, the goal is to help reduce transmission from asymptomatic carriers. Someone infected with the Coronavirus may not present symptoms for up to 14 days. During that time, they could be unknowingly infecting other people.

But there are a number of reasons for suggesting not wearing masks in public:

  • Prevent hoarding medical-grade masks needed by health professionals;
  • Not much medical evidence to show that it's effective;
  • May cause people to feel safe so they don't take other actions, like cleaning hands

But given how widespread the disease is, even methods that may have relatively small levels of effectiveness are worth reconsidering.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
