Conferences, concerts, sporting events, expos etc. They're just trying to slow down the rate at which it spreads. All of these types events also typically involve some amount of travel (whether on the part of the organizers, entertainers/presenters and attendees) It's not only the fact that it's a large number of people gathering, but also that it's a large number of people in close proximity to people they wouldn't otherwise be from out of town who are at higher risk of having been exposed to the virus. They pass it on to a few people at the event, who in turn take it home and give it to family members and in a few weeks the city has a big problem.
