The Government today gazetted a compulsory testing notice to require people who had been at Fung Chak House, Choi Wan (II) Estate for more than two hours from December 15 to 28 to undergo COVID-19 testing by December 31. It had earlier sponsored a multi-disciplinary team at the University of Hong Kong (HKU) to conduct a preliminary study on monitoring the COVID-19 virus level in sewage. The study revealed that the sewage samples in Ming Lai House and Fung Chak House at the estate constantly tested positive, implying that people infected with the virus might be present at the relevant places.
