This decision was made this morning (Tuesday) and includes no visitors to the acute ward and aged-care facilities Moyneyana House and Belfast House.

MHS Acting CEO Katharina Redford said essential service contractors and those attending urgent allied health appointments would be allowed to enter the campus.

The sole entry point to the campus will be through the community health building, with staff screening visitors to ensure they are not in high risk COVID-19 categories.

While access is limited to the campus, Mrs Redford said it was important for family and friends of residents and patients to stay in touch.

"This is about physical distance, not social distance, we have to keep socially connected," she said.

"We encourage people to keep contacted with family in care because that contact is very important for them."

Mrs Redford said each aged-care room had a phone and she encouraged families to look at upgrading residents technology if possible to make online communications an option.

She said the step up in isolation measures come on the back of Victoria declaring a state of emergency.

"The moves we are making here are in that category so that we can protect the most vulnerable members of our community," she said.

MHS has been proactive in its fight against the flu, with all residents at its Port Fairy campus having already received their flu shots.

She said when visitor restrictions were lifted, those coming in would need to have had their flu shot.
