Editorial | Making new health code system work is in the interests of all
- Compatible with those used on the mainland, the code will enable people from Hong Kong to cross the border and bring quarantine-free travel a little closer

Officials have made clear that the code is only required by those who cross the border. Users have to first register their full name and proof of home address, make a health declaration and have their vaccination and test records. Depending on individual circumstances, such as whether one is undergoing quarantine, been to places that require compulsory testing, or be within 21 days of arrival in the city, a coloured QR-code will be issued. Only those deemed to be risk-free will be issued a green code to cross the border.
Separately, a new version of the “Leave Home Safe” contact tracing app will be available for download. This will enable users to upload and share their whereabouts over the past 21 days with relevant authorities, should there be need to track movements because of infections.
Those who are concerned about privacy breaches will be relieved to learn that the government has no plans to mandate the use of the health code within the city. Nor is there any need to require those using the risk-exposure app to provide personal identification in the foreseeable future. But those who use the health code to cross the border must realise that their identities and whereabouts may be tracked in the event of infections. For the sake of health control, the arrangements seem necessary and fair.
The government is well aware of the logistical issues involved. In addition to enhancing public awareness via community reach programmes, there will be free smartphones for the needy as well as improvements for the visually impaired in using the Leave Home Safe app. They are pragmatic measures to get the community ready for the new challenges arising from the reopening of borders in times of growing concern over the Omicron variant.
The health code is not merely for the sake of those who travel. It is a new milestone in the joint efforts of Hong Kong and the mainland in fighting the pandemic as we all seek to return to normal public life. It is in the interests of the city and the country to make the code a success.
