Tested positive using Rapid Antigen Test

For people who obtained positive results through Rapid Antigen Test (RAT) for the first time can report via the online platform "Declaration System for individuals tested positive for COVID-19 using Rapid Antigen Test" (https://www.chp.gov.hk/ratp). All reporting must be done on the day of testing or the day after. If individuals encounter difficulties in using the online platform, they can call the automated system at 1836 119 to register their identification document and telephone number.
