Temporal and spatial concomitant is defined as within 14 days.

A spatio-temporal concomitant is a person who has stayed with the diagnosed patient for 10 minutes in the same temporal and spatial grid (usually 800 meters * 800 meters as the detection range) within 14 days***.

In layman's terms, for example, the diagnosed patient has traveled to Fuzhou within 14 days, and someone whose trajectory has intersected with him in these 14 days, whether it is physically rubbing shoulders or drifting in communication signals, may be identified as a temporal and spatial accompaniment. Upon detection by the system that this person has been temporally accompanied by a confirmed patient and is a temporally accompanied person in the at-risk population, the health code will turn yellow.
