In the world global i think there's a much wider range of views that're expressed. Covid zero is something that was discussed before delta, and certainly before amacron tatthis idea of maximal public helt intervention if even a single case appears in a society. But you had places like the irish parliament discussing whether there should be covid zero response versus more of a suppression response that allows a lower number of cases. And i do think your average public health worker or public health scientist wants a far more precautionary approach than the one that state and local and federal government is taking right now.
