Earlier quoted context omitted.
In Seoul, multiple emergency alerts asking people to keep 2 meter distance and to cancel trips and meetings were pushed to mobile phones for the first time yesterday morning. Pedestrian streets in popular districts are still fairly bustling tonight, even if less crowded given the season.
Pushing mobile alerts is what any country with half a clue should be doing. I get regular ones telling me to wash my hands and avoid contact, it's comforting to see them everyfew days.
(But then the government uses the same alerts to notify about strong winds and elevated pollution levels, so it’s more or less a given.)
The ones from yesterday were the first to ask people to limit their mobility.
