Hong Kong is preparing to introduce a tiered health-code system reminiscent of what’s used in mainland China to shorten mandatory hotel quarantine and better track Covid-19 patients who are isolating at home.

The system will assign a yellow or red code to individuals to manage their movement. Compared to mainland China, where everyone has a code, Hong Kong’s system will be far more limited for now and only be used on inbound travelers and those with the coronavirus. It also won’t be able to track individuals and where they go, unlike in China, said officials.
