Good news.

Health code color rules updated...

Shanghai has clarified its rules that dictate the color of a health code.

It's a Red Code for those...

  • Testing positive during individual or mixed sample testing

  • Confirmed, asymptomatic or suspected COVID-19 cases

  • Close and secondary contacts of confirmed, asymptomatic or suspected COVID-19 cases

  • Overseas returnees undergoing central or home quarantine

  • People from high-risk regions

And a Yellow Code for those...

  • Discharged confirmed or asymptomatic cases still under home quarantine

  • Risk groups, as designated by inter-provincial data research

  • Failing to take part in PCR screening

Think you've got the wrong color code and are being unfairly maligned? You can lodge an appeal – dial the 12345 hotline or make an online appeal on the suishenban app, where you can also check the reason for your red or yellow health code.
