While in NL the scientific advice and communication has been simply ridiculous (mandatory masks introduced at the end of last year, with still the idea that "science doesn't know if they work, but we are gonna make them mandatory" from the government, and "we're against that, they don't work" from the head of the CDC-equivalent), in Italy it does contain the cautious wording that I advocate for.
However, this is the official communication that is written in "legalese" and not passed through the people by means of interviews and press releases. The media of course bears a lot of responsibility for the dilution of the message, chasing scoops and making headlines that leave no space for doubt; but the communication of the government to the public ends up using similar headlines, which I see as the problem in this case.
What would you improve in the message sent? To me it seems the parts you ask for are pretty much there?
