Here's a real life example
@Kimmio Laughterlove that you can use to explain it.
The outbreak with the Misericordia started on June 21 in terms of positive tests. 14 days goes to July 4, inclusive.
There were still new cases happening, the most recent ones I have heard on occurred on July 9, there may be more that still occur.
How big of an area/how many people would you have expected to stay within that area? For how long?
Also, cases are accounted by residents, not where contracted, so while the Misercordia is considered to be the outbreak location, the workers/patients can account for various subhealth zones. That's true of many workplaces as well where outbreaks can occur - so how is that aspect handled?
