In a statement issued on Thursday, it urged government staff to work from home “as much as possible”, unless they are providing essential or emergency services, or involved in anti-epidemic work.
The administration said the latest measures must be implemented in order to reduce the number of people circulating in the community, as the Covid-19 situation deteriorates.
The special arrangement will last for at least a week until February 11, and authorities will continue to monitor the situation.
Private companies are also being encouraged to allow staff to work remotely.
The latest measure is a step up from what was announced just a week ago, when the government said that bureaux and departments would implement new special work arrangements “having regard to their operational needs”.
