Considering the balance between infection risks and resumption of economic and livelihood impetus, the Government decided to cancel the arrangement of issuing isolation orders to infected persons according to the Prevention and Control of Disease Regulation (Cap. 599A) from January 30. For details, please refer to press release.

The evaluation criteria for COVID-19 nucleic acid test results will be adjusted with effect from 16 January 2023. Test results issued from that day with a Ct value of 35 or above would be regarded as negative for purposes other than clinical management. The Centre for Health Protection of the Department of Health would not regard persons with results of nucleic acid tests at a Ct value of 35 or above as confirmed cases starting from 0.00am on the same day. For details, please refer to press release.

The Government announced on 28 December 2022 that local anti-epidemic measures will be further adjusted starting from 29 December 2022, including removing definition of close contacts and ceasing issuance of quarantine orders. For details, please refer to press release.

After Recovery

For some recovered persons, viral genome fragments in the body may present in nucleic acid tests. As such, for confirmed cases who have recovered and finished isolation, they do not need to take other nucleic acid tests within three months from the specimen collection date of positive test result, unless they are instructed by a healthcare professional or the Government to undergo testing.

Moreover, recovered persons should refer to “Factsheet on COVID-19 Vaccination for Persons with Prior COVID-19 Infection”.
