Epidemic prevention and control measures have been upgraded. What happened when the green code suddenly turned yellow?

On 20021120, the situation of epidemic prevention and control in China escalated again, and various localities began to strengthen epidemic prevention and control measures. At this time, many people found that their green code suddenly turned into a yellow code, and many people were puzzled. So, what happened when the green code suddenly turned yellow?

1. What are the green and yellow codes?

Green code and yellow code are health codes adopted in the epidemic prevention and control in COVID-19. The green code indicates that the holder has not been to the epidemic area in the past 14 days, has not been in contact with confirmed patients, suspected patients or close contacts, and has no symptoms such as fever and is healthy. The yellow code indicates that the holder has a travel history in areas with high epidemic risk or has had contact with confirmed patients, suspected patients or close contacts, but has no symptoms such as fever, and needs to be isolated for observation.

Second, why does the green code suddenly turn into a yellow code?

The reason why the green code suddenly turned into a yellow code was mainly due to the escalation of epidemic prevention and control measures. Before the epidemic prevention and control measures were upgraded, the standard of green code was relatively loose. As long as you haven't been to high-risk areas in the past 14 days, you can get the green code. However, after the situation of epidemic prevention and control changed, all localities began to strengthen epidemic prevention and control measures and adjust the green code standard. Now, if you have ever been to a high-risk area, even if you have returned to your original residence, you may be judged as a yellow code.

Third, how to prevent the green code from turning into a yellow code?

In order to prevent the green code from turning into yellow code, we need to do the following:

1. Avoid going to areas with high epidemic risk. If you really need to go to these areas, try to reduce going out and pay attention to personal protection.

2. Avoid contact with confirmed patients, suspected patients or close contacts. If necessary, wear a mask and keep a social distance.

3. Pay attention to personal hygiene. Wash your hands frequently, wear a mask, gather less, ventilate more, and do a good job in personal hygiene protection.

4. Actively cooperate with epidemic prevention and control measures. If necessary, cooperate with nucleic acid detection and isolation observation.
