1 imported COVID-19 case detected

July 13, 2021

The Centre for Health Protection said today it is investigating one additional COVID-19 case involving a 27-year-old woman who arrived from Cambodia.


A total of 31 cases were reported in Hong Kong in the past 14 days, including one local case with an unknown infection source, 29 imported cases and one import-related case.


The centre has been conducting epidemiological investigations into an earlier confirmed case involving the L452R mutant strain. The 50-year-old man worked as a porter at the apron of Hong Kong International Airport.


Genetic sequencing revealed that this case involved the L452R mutant strain but it was found to be different from that in the case involving a 27-year-old airline ground crew staff member with the Delta mutant strain.


Genetic analysis of the porter’s case is found to be related to the genomes of four imported cases from Russia, one of which involved an aircrew member of cargo flight RL9933 on which the patient had served.


According to the centre’s latest epidemiological investigation, among the flights that this patient had served during the incubation period, there was one confirmed case involving an aircrew member of flight RL9933 arriving from Moscow on July 6.


While the patient had no direct contact with the infected aircrew member, he had stayed and worked in the cabin for several hours, during which some turn-around aircrew members had stayed in the plane.


The centre said the patient might have been infected by some undiagnosed cabin crew on this Russia flight. It is following up on the case with overseas health authorities.


In relation to a non-locally confirmed case involving the L452R mutant strain and a man who had lived in Hong Kong, any person who had been at six specified premises during the specified period must undergo additional testing, including those who have completed a COVID-19 vaccination course.


A school that reported an outbreak of upper respiratory tract infection or influenza-like illness is covered in the compulsory testing notice today as a precaution.


The service period of the mobile specimen collection station at North Transition Deck, L6, Terminal 1, Hong Kong International Airport will be extended to July 17.
