You always fight the last war. Covid measures started as flu measures, and to a great extent still are even though we now know (and knew fairly early) that the transmission modes differ significantly.

I thought we know by now that transmission mode is more similar than initially thought? That is, it's mostly airborne for both covid and flu.

Flu has significant fomite transmission, both direct and from emissions, where CoV-2 basically has none. Aerosol transmission is present in flu, but nowhere near as strong as CoV-2. There are definitely some overlaps, like direct large droplet transmission (which make measures like masks work for both.)

Sanitation and "social distancing" work for flu, but coronavirus is mainly about ventilation.

So hand washing is much more important for the flu? That's great because it is much more in your control than ventilation
