Chuang Shuk-kwan, head of the communicable disease branch of the Centre for Health Protection, said if both infected flats from the same building are found to be linked to previously confirmed cases, mandatory tests will not be triggered. Health authorities will trace the records on buildings fulfilling the requirement over the past two weeks and issue mandatory test notices accordingly. Both buildings will be added to the mandatory test list. Chuang said Hong Kong yesterday had 53 confirmed cases - 23 males and 30 females - aged six months to 86 years old. More than 40 preliminary positive cases await confirmation.
