Separately, 657 additional imported cases were reported, comprising 544 cases that tested positive by nucleic acid tests (115 confirmed cases, 400 asymptomatic cases and 29 cases with pending status) and 113 cases that tested positive by RATs. Among the additional imported cases, 370 of them involved samples at the airport, 217 involved samples during Day 1 to Day 3, and the remaining 70 involved samples during Day 4 to Day 7.
Hong Kong has recorded a total of 1,063,100 and 1,094,876 cases that have tested positive by nucleic acid tests and RATs respectively for the SARS-CoV-2 virus so far.
The CHP is continuing with epidemiological investigations of the cases. Please refer to the Annex and the “COVID-19 Thematic Website” (www.coronavirus.gov.hk) for more information.
The CHP has been closely monitoring the situation of positive cases involving mutant strains by genetic analysis. As of 0.00am today, the DH’s Public Health Laboratory Services Branch (PHLSB) had identified 225 cases of sub-lineage XBB, six of XBD, eight of BA.2.75.2, seven of BA.4.6, 13 of BF.7 and 36 of BQ.1.1 among imported cases in Hong Kong, while 104 cases of sub-lineage XBB, 18 of XBD, one of BA.2.75.2, four of BF.7 and 121 of BQ.1.1 have also been detected among local cases.
Among the specimens received by the DH’s PHLSB during 25th November to 1st December for verification testing of local cases, 0 per cent and about 71.32 per cent of them (seven-day moving average) are related to the sub-lineages BA.2.12.1 and BA.4/BA.5 (including suspected cases) of the Omicron mutant strain respectively.
In addition, as of 0.00am, 4th December, a total of 10 593 death cases that had tested positive for the SARS-CoV-2 virus during the fifth wave (since 31st December, 2021) were recorded, with 10,497 and 92 deaths reported from the Hospital Authority and public mortuaries respectively as well as four deaths reported from private hospitals. Hong Kong has so far recorded a total of 10 806 death cases that tested positive for the SARS-CoV-2 virus. 16 patients have passed away in public hospitals.
Furthermore, among the earlier cases by nucleic acid tests reported, there were cases (including pending cases) that were changed to confirmed, asymptomatic or re-positive cases. As of yesterday (December 3), the total number of confirmed cases was 462 800, while the figures for asymptomatic cases, re-positive cases and pending/unknown cases recorded since January 1 were 350 707, 31 and 247 002 respectively.
