Dr. Fauci has spoken.
It might seem pretty dystopian that top U.S. infectious disease experts now recommend Americans wear cloth masks outside, particularly in places like markets. But there’s a good reason why.
As the coronavirus spreads rapidly around the nation, a significant number of infected people may never show any symptoms (perhaps as high as one in four people). What’s more, it takes an average of five days after infection for symptoms to develop in those that do eventually have symptoms. So there are likely a lot of unwitting carriers around outside.
