The government has lifted a lockdown on a residential block in Sham Shui Po, where 29 preliminary positive cases were found.
Authorities said the lockdown at Fu Yuet House in Fu Cheong Estate was lifted at 8:30am on Wednesday, and that around 4,820 people went through two rounds of testing.
A compulsory test notice was imposed on Fu Yuet House on Monday evening after sewage samples from the block tested positive for Covid, and authorities said there was a higher risk of infection.
The lockdown was meant to end on Tuesday morning but was extended for another day.
