Many (most?) places around the world have changed the way they do things so as to limit the spread of coronavirus. These measures are currently seen as temporary. I wonder how long covid-19 needs to be a major threat before these "temporary" measures become permanent cultural / legal fixtures. E.g., updates to building codes, or conversion of executive emergency orders into permanent law. For example, modifying building codes for retail/office space to reduce risk of person-to-person transmission via bio-aerosol.
