It isn't just covid either. Covid has really brought to light the general risk of transmissible disease at these events as well. I want to see conferences setting and meeting standards for air filtration. There's no reason so many people need to come home sick from conferences. We expect clean water to drink, we should expect clean air to breathe.

yeah, I think conferences may want to brand these as airborne disease policies, not covid policies. Especially in places where multi-disease rapid testing is available (as I understand is now common in the EU and eventually coming to the US).
