Reviewer feedback on this answer:
The answer does not relate to how many people can be allowed at an event, which is the point of the original question.
This has nothing to do with guests at an event.  It doesn't even mention a single thing about an event.

What steps should I take if an attendee or staff person develops symptoms of COVID-19 while at the event?
section_content: If a staff member or attendee becomes sick at your event, separate them from
others as soon as possible and until they can go home. Provide them with

to wear, if available. If not available, provide them with a tissue or some
other way to cover their coughs and sneezes. If needed, contact emergency
services for those who need emergency care. Public transportation, shared
rides, and taxis should be avoided for sick persons. Be sure to contact local
public health officials regarding the possible case of COVID-19 at your event
and how to communicate with staff and attendees about possible exposure to the
virus. Read more about preventing the spread of COVID-19 if someone is
sick.

This answer does not relate to the original question, of how many people are allowed at an event at one time.
This clip talks about events.  It does give good information about an event.  However, it doesn't answer the specific question about an event.

Reviewer feedback on this answer:
The original question asks how many people are allowed at an event, not in the case of when to cancel.
This answers the question perfectly.  It answers the exact question that is asked and lets the people know exactly how many people are allowed at an event.
