Points to Note for Persons who Tested Positive

When you are tested positive for COVID-19 and notifi¬ed via Short Message Service (SMS), or obtain a positive Rapid Antigen Test (RAT) result, you will be considered as infected. Your household member(s) will be considered as close contact(s). Please provide information to the Centre for Health Protection through the links below.

To enable people who tested positive to update and supplement information submitted via the online declaration platforms ("Declaration System for individuals tested positive for COVID-19 using Rapid Antigen Test" (www.chp.gov.hk/ratp) and "Online self-reporting for COVID-19 patient" (www.chp.gov.hk/cdpi)), the DH has added new functions for them to update the mobile number of themselves and their household contacts for receipt of SMS, and to add relevant information of household contacts who have not been declared previously, within seven days after the first submission via the online platforms for one time only. The relevant systems will not handle any request for an information update submitted beyond the seven-day period after the first submission.

Please note: When filling in information, “household contact” does not include those who is currently preliminary positive for COVID-19 or confirmed for COVID-19 within the past 90 days.

For details, please refer to ‘Handbook for Persons Tested Positive for COVID-19’.

Tested positive or preliminary positive by Nucleic Acid Test

People with positive or preliminary positive nucleic acid test results will receive an SMS notification about the result, together with a request to fill in an electronic form (https://www.chp.gov.hk/cdpi) to submit information, including those on family members living in the same household. This is to facilitate the work of the Centre for Health Protection such as epidemiological investigation and arrangement of hospital admission, isolation and quarantine. People who receive the relevant SMS should check the personal information and information on testing in the SMS carefully and fill in the electronic form as soon as possible to provide accurate and complete information.

Tested positive using Rapid Antigen Test

People who obtain a positive result through an RAT have to report via the online platform "Declaration System for individuals tested positive for COVID-19 using Rapid Antigen Test" (https://www.chp.gov.hk/ratp) as soon as possible by the reporting deadline. Please click here to watch the demonstration video. Note: Relevant individuals, who completed initial reporting via the "Declaration System for individuals tested positive for COVID-19 using Rapid Antigen Test" as well as their household contacts that, after receiving an SMS with the reference number concerned, they should follow the link to log-in and upload their supporting documents (photo of the RAT result and/or identity document) as soon as possible, so as to facilitate a speedy epidemiological follow-up of the Centre for Health Protection for appropriate support for patients with higher risks. Logging-in to the linked website provided in the SMS will only be valid for 24 hours after the SMS was sent. Relevant individuals must upload the supporting documents within 24 hours upon receipt of the SMS, or else their log-in will become invalid and they would not be able to upload supporting documents with the link and download their isolation or quarantine order issued by the Centre for Health Protection in accordance with the law. In addition, they will not be able to report again via the system.
All RAT reporting must be done on the day of RAT testing or the day after. The Centre for Health Protection of the Department of Health (CHP) will not process and follow up those reports made beyond the deadline. If individuals encounter difficulties in using the online platform to declare RAT positive results, they can call the automated system at 1836 119 to register their identification document and telephone number. The Centre for Health Protection will contact the relevant person later to finish the report procedure.
Positive RAT results reported through the system may be required to undergo nucleic acid test by the CHP. Cases confirmed to be negative by the nucleic acid test will be deleted from the confirmed case record. The relevant persons will no longer be able to use the quarantine orders issued by the Government, recovery QR code records or any other relevant documents as a proof of recovery.

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”.
