The Superintendent of Public Health Charmaine Gauci said that out of the estimated 1,200 Maltese people under quarantine, 143 are healthcare workers.
This amounts to just under 12% of the total people quarantined.
Of the 143 quarantined healthcare workers, 77 work at Mount Carmel Hospital, 56 work at Mater Dei, seven work at Karin Grech Rehabilitation Hospital, two work at the Gozo General Hospital, and one works at Primary HealthCare.
Earlier this week, Mount Carmel Hospital halted all visits following a COVID-19 outbreak on the premises.
Along with the infected members of staff, seven patients also tested positive for the virus.
Only recently, Mater Dei visits have been subjected to tighter restrictions to protect patients at the hospital.
