Apparently you missed the point of this article — apparently she was trying to leave the apartment. Suppose she did leave her apartment and no one knew. Maybe they didn’t have guards at her door 24/7?

Sure, having an exposed family just quarantined under the “honor system” is a risk, no doubt about that.
However, if they are properly contained, there is no risk to the neighbors.
