Comes down to censorship like was practised during the Spanish Flu (incorrectly named as it did not originate from Spain at all, but was reported widely there). Although 'not talking to the media' is a general condition for many companies, where there are immediate threats to lives I don't think a bureaucratic principle should apply? Surely we learnt from the Spanish Flu that trying to keep it quiet actually cost lives. We as citizens surely need to know if extraordinary pressure must be brought to bear results. I would not want to already be in hospital and wondering why the nurses are not wearing masks or why I can't then get a respirator - it's too late then.
If hospitals and politicians do not want doctors and nurses to speak out, then the hospitals and politicians themselves need to be completely frank and be communicating themselves. If not, then they are contributing to lives being lost.
