It comes as the government urges the region's residents to get tested.

Premier Daniel Andrews identified Greater Bendigo's virus infections among those of concern during press conferences on both days of the weekend.

There were 49 active cases of COVID-19 in Greater Bendigo in the 24 hours to Sunday.

There were 56 cases active on Friday, when Mr Andrews was asked to respond to Cr O'Rourke's calls for more detailed data.

The premier had not heard the Bendigo mayor's comments before replying.

The Bendigo Advertiser sought a more detailed reply from the premier's office.

"We respect the privacy of patients and don't provide details about individual cases unless it is necessary to do so in the interests of public health," a Department of Health and Human Services spokesperson responded.

They urged the region's residents to comply with restrictions.

"No matter where you live, if you have a legitimate reason for leaving home you must wear a mask, physically distance from other people and practice good hygiene, such as handwashing," the spokesperson said.

"All it takes is one positive case to set the virus off again in any of our regional communities.

"If you have even the mildest of symptoms, please get tested and stay home."

Cr O'Rourke said she would continue advocating for the disclosure of suburbs, "as we believe this would be important information that could help keep our community safe and limit the spread of infection by community transmission."

"Ultimately, we want our community to be aware that anyone in the community could have COVID-19 and we want our residents to respond accordingly, taking on board the advice and precautions from the Department of Health and Human Services," the mayor said.

"The feedback from our community and health professionals is that in a regional setting more detailed data at a suburb or precinct level, while protecting privacy, would help keep our residents focussed on limiting their movements."

She said the premier had not called in response to her comments, but she had spoken with staff from the department.

Mr Andrews told reporters at Friday's press conference he'd be happy to call the mayor of Bendigo in response to her comments, if needed.

Cr O'Rourke said she had explained her advocacy to department staff, who sought to understand her position on the matter.
