How to declare the health declaration code in Hong Kong when it turns red?

Hello, dear, I'm glad to answer your question. Hong Kong health declaration code turns red. The declaration process is as follows: Relevant information: 1. Click on the health code transcoding registration to find the health code transcoding registration in the health code. 2. Select the red code transcoding application, and then click the red code transcoding application in the page. 3. Submit the transcoding application after uploading the certification materials. First of all, you need to contact the local community immediately and do centralized isolation or home isolation according to local prevention and control regulations. Secondly, during the isolation period, we should strictly cooperate with the local health monitoring and management, and accept nucleic acid sampling and testing according to the prescribed frequency. If you feel unwell, report it in time. When you have completed the quarantine period, and your nucleic acid test result is negative and you are in good health, your health code will be automatically changed to "green code" after the local evaluation shows that you meet the conditions for lifting the quarantine. ：
