Coronavirus: More staff at Tasmanian hospital have COVID-19

Two more staff at a hospital in Tasmania's northwest have tested positive to the coronavirus, with authorities banning visitors from the facility.

The new cases at the North West Regional Hospital (NWRH) in Burnie were confirmed by the state's public health department overnight.

It takes the number of NWRH staff who have tested positive to six, with an inpatient also previously testing positive.

The NWRH has been closed to visitors, as has the Mersey Community Hospital near Devonport in the north, but exemptions exist on compassionate grounds.

The inpatient had been taken to the Mersey Community Hospital before they tested positive.

Health authorities are working to identify and contact any close contacts of the two staff with the virus.

"We acknowledge the current situation is creating concern, both for staff and for the community," Chief Medical Officer Tony Lawler said in a statement.

"We are taking every action in accordance with best advice to ensure possible contacts are identified as quickly as possible."

All emergency patients from the Devonport region will be transported to Launceston General Hospital as a temporary measure.

Tasmania has recorded 89 virus cases and two deaths, one of them an elderly woman at the NWRH last month.
