HONG KONG – Hong Kong reported one imported COVID-19 case on Tuesday, pushing the city’s tally to 11,952, as health authorities said a case involving an airport porter was linked to four imported cases from Russia.

The case involved a 27-year-old woman who flew in from Cambodia and underwent hotel quarantine at JEN Hong Kong by Shangri-La in Shek Tong Tsui on Hong Kong Island, according to a statement issued by the Centre for Health Protection.

The Centre for Health Protection traced the airport porter, carrying the Delta variant, to four imported cases from Russia after conducting genetic sequencing

The porter, carrying the Delta variant, was found to have worked on cargo flight RL9933 on July 6. One of the crew members on the flight, a 45-year-old man, was later confirmed as infected.

“(The porter) has stayed and worked in the cabin for several hours of this flight where some turn-around aircrew members had stayed all along. (He) might have contracted the virus from some undiagnosed cabin crew,” the CHP said in a statement.
