The blue 24-hour negative nucleic acid test results are not beyond the standard of epidemic prevention measures, but for the convenience of inspection.
For example, some cities in China once required to hold a 24-hour nucleic acid negative certificate before leaving the local area when a staged epidemic just happened. For technical reasons, at that time, Yuekang code could only display the "purple code" with negative nucleic acid for 48 hours. Therefore, the blue health code is enabled at this time in order to update this function and adapt to different epidemic prevention needs more accurately.
Other colors:
The results of nucleic acid test turned green within 2 days, and gradually turned purple within 6 to 10 days. Once the residents are more than 10 days away from the last nucleic acid test result, the nucleic acid test certificate button will be displayed in gray, and the text prompt "No result" will be displayed.
