What is the reason why Putian Health Bao can't make an appointment?

Health Bao shows that failure means that nucleic acid expires after 48 hours. But the health treasure can't fail. Because the health code has no validity period, it will play an important role in the whole epidemic prevention and anti-epidemic period. If it fails, the consequences will be very serious, people will not be able to know their physical health in time, and they will lose effective monitoring of their physical health. The establishment of health code is to effectively and timely monitor the personal health status of citizens. It is based on one-code communication and is a part of one-code communication. At the same time, it takes personal nucleic acid detection as the sole basis to prompt personal health information in time and accurately, and plays an irreplaceable role in fighting the epidemic.
