It is the first time staff associated with the NWPH have been confirmed to have coronavirus.

Four of the new cases are patients who have recently received care at both NWRH and NWPH. These patients are now being cared for in the NWRH.

One of the nine cases recently returned to Tasmania from the United States, and another case is a close contact of a previously identified case.

There are now 22 coronavirus cases linked to the NWRH, made up of a total of 15 health workers, six former patients, and a close contact of a previous NWRH case announced on Tuesday.

Eight of the new cases are women and one is a man.

One is from southern Tasmania and eight are from the north-west.

Director of Public Health Mark Veitch said Public Health Services was deploying three staff, including a field epidemiologist, public health physician and public health nurse to support the Outbreak Management Team.

The team was set by the Tasmanian Health Service to manage the outbreak in the north-west.

"The Outbreak Management Team is already identifying and contacting persons who had close contact with these staff and patients and will ensure necessary actions are taken," Dr Veitch said.

"Public Health Services is following up household and social contacts of the cases.

"If any hospital staff member or patient is determined to be a close contact of these cases, they will be contacted and advised of the action they need to take.

"It may be necessary for other staff and patients to be tested for coronavirus as investigations progress. We will assess and test any symptomatic staff member or patient."

The latest jump in cases comes after Tasmania's Premier Peter Gutwein announced residents in the state's north-west would be closely monitored by police over Easter, as the outbreak continued to spread across the region.

Drive-through testing began on Hobart's waterfront today, and additional testing stations have been set up in Launceston and Devonport in the state's north and north-west.

The latest coronavirus-related death in Tasmania occurred on Tuesday when a man who had spent time onboard the Ruby Princess cruise ship passed away on Tuesday.
