The lockdowns cover two blocks in Phase Three of Kwan Yick Building on Des Voeux Road West in Sai Ying Pun, as well as Hoi Kung Court and Hoi To Court on Gloucester Road in Causeway Bay.
Authorities say residents must get tested for the virus and they’ll be required to present their test result before being allowed to leave the site.
Officials say they expect the two operations to be completed by around 7 or 8 am on Thursday to allow residents to go to work.
The operations were announced after the Centre for Health Protection said confirmed cases had recently emerged from these residential blocks.
The government said there is a high risk that the virus could spread in these areas because of the age of the buildings, as well as the prevalence of sub-divided units inside the blocks.
