@GottaLaff In any situation you know you could be exposed, this is the one you want to wear a mask and shield for because its transmission is both airborne and fomite. ( #COVID has very low surface transmission) A benefit people miss w/ shields is they stop you from touching your eyes, nose & mouth. Shields work both as a barrier & that one extra step that helps you remember not to. Fomite virus transmission that results in illness is a numbers game. Less touching = less virus transmission.
