You’re allowed to leave your house. Exercise, pet walking, and essential shopping and other essential activities aren’t banned. Put on a mask and go for a walk in your neighborhood and keep social distancing.
Right - this is obviously what I would do. However, if face shields were helpful for reducing risks for general interaction (no idea if they are) then I’d also want one. The fastest path to leaving the house is reducing the risk of leaving, so some simple PPE (that is more effective than a mask) would be great.
