In response to online platform Mothership's queries, the MOH stated that an internal circular on the matter had been issued on October 16 to public healthcare institutions.
The ministry said that it recognised the need for staff to "recharge and rest" after fighting the pandemic for a long period of time.
"The public healthcare institutions will work to strike a balance for leave applications from staff so that staff can take turns to go on leave, while providing sufficient staffing for essential healthcare services," it said.
"Staff should continue to comply with prevailing national travel advisories. As with any leave applications, they will need to discuss the duration and timing of their leave applications with their supervisors, and comply with any internal guidelines that may be communicated to them by their institution. If in doubt, staff should check with their institution for further details," it added.
Separately, another circular said that healthcare workers would no longer be subjected to additional testing requirements and restrictions upon returning from overseas travel.
However, staff working in settings deemed "high risk" may be required to undertake additional measures upon their return.
