How does Nanchang red code become green code?

When punching in the hygiene code, if the code is red, it means that you can't go out for the time being and need strict isolation. Red team cannot be directly turned into a green code, but it must be turned into a yellow code before it can be turned into a red team. A * * * takes 28 days.

All the confirmed cases from "red code" to "yellow code" were cured and discharged, and there was no recurrence symptom in isolation period 14 days. After diagnosis, COVID-19's case was excluded, the isolation period was 14 days, and there was no COVID-19's symptom, and a "yellow code" was issued. Close contacts who changed from "yellow code" to "green code" did not have COVID-19 symptoms after traffic adjustment. After isolation 14 days, the "yellow code" changed to "green code".

Health code traffic information comes from data collected by the state. After prevention and control rules, data modeling and background comparison, three COVID-19 risk levels are judged and displayed in three colors: green, yellow and red.
