Bupa's aged care home in Traralgon in eastern Victoria is now dealing with the largest outbreak of coronavirus in regional Victorian aged care outside of Melbourne and Geelong.
Eight people, including four residents and four employees, have now tested positive for coronavirus in the past two weeks.
The outbreak was sparked by an infected but asymptomatic Melbourne health worker who visited the aged care home on July 16.
Testing this week has turned up another three cases in the past day.
A spokesman for Bupa said the company had been in touch with employees, residents, and their relatives to let them know that a further two staff members had tested positive.
"Another team member, who has been self-isolating and hasn't been in the care home for almost two weeks, also returned a positive test during this time," the spokesman said in a statement.
All residents and staff to be retested
The three infected staff members are isolating at home as stage three restrictions come into force in regional Victoria.
"They will not return to the care home for at least two weeks from the date of their positive test and on advice from the Public Health Unit," the spokesman said.
"While this news is difficult for all involved in the care home, our team is maintaining our strong focus on infection control including regular deep cleaning, separating of communities, and the use of full personal protective equipment," the spokesman said.
"We continue to monitor the health of all our residents closely."
All residents and employees at the Bupa aged care home in Traralgon will undergo further testing today.
The operator said it would be in touch with residents and their loved ones as soon as their results were available.
Visitors have not been allowed into the nursing home since July 8, almost a month.
In Ballarat, a cluster of five staff and residents were infected at the dementia specialist aged care home Bill Crawford Lodge run by Ballarat Health Services.
