    Hundreds of occupants of a 52-storey residential block in Tung Chung have been ordered into quarantine in Hong Kong?s biggest such operation after one of them was confirmed to have contracted a mutated strain of Covid-19 from an unknown source locally for the first time in the city.

    ... Occupants will have to undergo three weeks of quarantine in government centres.

    Health officials said the patient was a 39-year-old domestic helper from the Philippines, and her infection carried the N501Y and E484K mutations. Both types were found in more infectious strains first identified in South Africa and Brazil, and further sequencing would be needed to determine the variant.

    Authorities cordoned off Tower 11 of Carmel Cove at the Caribbean Coast housing estate at 7pm for a lockdown exercise expected to end at around 7am on Friday after testing of all residents was completed.

    China Rocked by Double Mutant COVID Strain As Nation Fears Fresh Outbreak

    BY JOHN FENG ON 4/29/21 AT 10:38 AM EDT

    The "double mutant" coronavirus strain that was found in India has now been detected in China, the country's chief epidemiologist has said in a major announcement ahead of this weekend's public holiday.

    At a Chinese Center for Disease Control and Prevention press conference held in Beijing on Thursday, Wu Zunyou revealed the "Indian variant" had been found in "some Chinese cities," without elaborating. The news has sparked intense discussion online about stricter border controls amid the five-day Labor Day break beginning Saturday.

    The country where COVID-19 was first reported some 16 months ago is preparing to step up public health measures in order to allay fears of a fresh outbreak caused by the "double mutant" strain B.1.617.

    The strain first detected in India last October has now reached China ahead of Labor Day holidays beginning this weekend.
