What does it mean that the health code shows someone related to the epidemic?

According to the health standards, the personnel related to the epidemic situation refer to those who are involved in the work in the epidemic area and those who are in contact with the epidemic area. During the epidemic period, according to the instructions of the national epidemic prevention and control work, administrative units at all levels and epidemic prevention working groups should treat epidemic-related personnel strictly and cautiously, without discrimination or exclusion, and closely track health information. Regardless of their status and responsibilities, they are given equal treatment.
