What does it mean that people who live together don't need to be accused together in family health monitoring?

People who live in isolation at home are required to assign codes during isolation. I and the people who live in * * * strictly don't go out and refuse all visits. During this period, sampling personnel from community organizations will come to collect nucleic acids. Family health monitors do not have to go out during the management period, but there is a big difference, that is, their activities with residents are not restricted.
