Reacción a "Reactions on the desirability of maintaining the mandatory use of face masks on public transport "

Measures should always be proportionate to the risk situation. It must be clearly explained to the population why masks are kept indoors only and not in other areas. To help ensure compliance, the measures must be understood by the public.

We also need to be a bit more rigorous about "let the experts advise". Many of the measures have been political, with more or less technical recommendations, but political. We should not be afraid to say that and we should not abuse the catchphrase "the experts" to exempt decision-making. These, in essence, must have a very high scientific and evidence-based component.

Most importantly: more than individual protective measures (masks), I am concerned about the poor or absent regulation of protective environment measures (ventilation). I am not denying the need for the use of masks in certain situations, but I find it incredible that we have made almost no progress in the regulation of protective spaces. We continue to put the onus on the individual instead of looking for rules and regulations for healthy spaces and environments.
