Residents in precautionary zones will be required to undergo antigen testing twice a week. Police officers, couriers, and city infrastructure staff will undergo both antigen and nucleic acid testing regularly, according to the government.

Should a new COVID-19 infection be identified in a precautionary zone, the area will immediately be designated a lockdown zone.

In addition, if a community is located between compounds listed as lockdown zones, the district authority can choose to manage it as a lockdown or controlled zone.
