Why does the health code turn yellow? There are many reasons for this. First, if you have been to a high-risk area or passed through a high-risk area and stayed for 4 hours, our health code may change and turn yellow or even red.
Secondly, there are time and space partners. If we are time and space partners, our health code will turn yellow. Time-space companion mainly means that we are in the same space with people who have been diagnosed with COVID-19, such as the same indoor area.
Second, the health code turns yellow. What can we do to make it come back?
When the health code turns yellow, we don't need to worry too much. As long as we follow the local epidemic prevention requirements, our code will change back to green. At present, the relevant epidemic prevention requirements in various places require two nucleic acid tests within three days. If the two nucleic acid tests are negative, then our health code will turn green, and the cost of the two nucleic acid tests will be reimbursed by the local government department, so we don't need to spend any money.
Simply put, if we have been to or passed through areas with high epidemic risk and stayed for 4 hours, our health code may change and turn yellow or even red.
And a time companion. In other words, we have been in the same space, such as the same indoor area, with people diagnosed with COVID-19.
